11.4 Прочитай и письменно переведи текст STRUCTURAL SYSTEMS:
The structures of buildings are mostly skeleton frames of various types. New domestic housing in many parts of the world today is commonly made from timber-framed construction. Wood products are becoming a bigger part of the construction industry. They may be used in both residential and commercial buildings as structural and aesthetic materials. In buildings made of other materials, wood is still found as a supporting material, especially in roof construction, in interior doors and their frames, and as exterior cladding.
Laminated veneer lumber functions as beams to provide support over large spans, such as removed support walls and places where dimensional lumber is not sufficient, and also in areas where a heavy load is bearing from a floor, wall or roof above on a short span. Wood I-joists are used for floor joists on upper floors. They are engineered for long spans and are doubled up in places where a wall will be aligned over them. Glued laminated beams are created by glueing the faces together to create beams. By glueing multiple, common sized pieces of lumber together act as one larger piece of lumber. Manufactured trusses are used in home construction as a pre-fabricated replacement for roof rafters and ceiling joists. It is seen as an easier installation and a better solution for supporting roofs as opposed to the use of lumber struts and purlins as bracing.
Steel is one of the major structural materials in buildings. It is a strong and stiff material. It can be quickly fabricated and erected. The lightest and most efficient structural shape is the bar (or open web) joist, a standard truss made with angles for the top and bottom chords, joined by welding to a web made of a continuous bent rod. It is used almost exclusively to support roofs and can span up to 45 metres. The standard rolled shapes are frequently used as beams and columns, the wide flange, or W shape, being the most common. Where steel beams support concrete floor slabs poured onto a metal deck, they can be made to act compositely with the concrete.
Steel columns are joined to foundations with base plates welded to the columns and held by anchor bolts embedded in the concrete. The erection of steel frames at the building site can proceed very rapidly, because all the pieces can be handled by cranes and all the bolted connections can be made swiftly by workers with hand-held wrenches.
Reinforced concrete is also a major structural material in buildings. In situ concrete is used for foundations and for structural skeleton frames. The oldest framing system is the beam and girder system, whose form was derived from wood and steel construction: slabs rest on beams, beams rest on girders, and girders rest on columns in a regular pattern. This system needs much handmade timber formwork, and in economies where labour is expensive other systems are employed. One is the pan joist system, a standardized beam and girder system of constant depth formed with prefabricated sheet-metal forms. The simplest and most economical floor system is the flat plate where a plain floor slab rests on columns spaced apart. If the span is larger, the increasing load requires a local thickening of the slab around the columns. Concrete columns are of rectangular or circular profile and are cast in plywood or metal forms. The reinforcing steel never exceeds 8 percent of the cross-sectional area to guard against catastrophic brittle failure in case of accidental overloading.
Precast concrete structural members are fabricated under controlled conditions in a factory. Members that span floors and roofs are usually pretensioned, another prestressing technique, which is similar in principle to post-tensioning. Precast prestressed floor elements are made in a number of configurations. These include beams of rectangular cross section, hollow floor slabs, and single- and double-stem T shapes. Precast concrete columns are not usually prestressed and have projecting shelves to receive floor members. At the building site, precast members are joined together by a number of methods, including welding together metal connectors cast into them or pouring a layer of in situ concrete on top of floor members, bonding them together. Precast prestressed construction is widely used, and it is the dominant form of construction in Russia and Eastern Europe.

11.7 Прочитай, переведи текст BEAMS и расположи абзацы в правильной последовательности:
1. Beams generally carry vertical gravitational forces but can also be used to carry horizontal loads (i.e. loads due to an earthquake or wind). The loads carried by a beam are transferred to columns, walls, or girders, which then transfer the force to adjacent structural compression members.
2. A beam is a structural element that is capable of withstanding load primarily by resisting bending. The bending force induced into the material of the beam as a result of the external loads and external reactions to these loads is called a bending moment.
3. Internally, beams experience compressive, tensile and shear stresses as a result of the loads applied to them. Typically, under gravity loads, the original length of the beam is slightly reduced to enclose a smaller radius arc at the top of the beam, resulting in compression, while the same original beam length at the bottom of the beam is slightly stretched to enclose a larger radius arc, and so is under tension. Above the supports, the beam is exposed to shear stress.
4. Most beams in reinforced concrete buildings have rectangular cross sections, but the most efficient cross section is a universal beam. A universal beam is only the most efficient shape in one direction of bending: up and down looking at the profile as an I. If the beam is bent side to side, it functions as an H where it is less efficient. The most efficient shape for both directions in 2D is a box (a square shell), however the most efficient shape for bending in any direction is a cylindrical shell or tube. Efficiency means that for the same cross sectional area (volume of beam per length) subjected to the same loading conditions, the beam deflects less. Other shapes, like L (angles), С (channels) or tubes, are also used in construction when there are special requirements.
5. Beams are characterized by their profile (the shape of their cross- section), their length, and their material. In contemporary construction, beams are typically made of steel, reinforced concrete or wood. One of the most common types of steel beam is the I- beam or wide-flange beam (also known as a universal beam or, for stouter sections, a universal column). This is used in steel- frame buildings and bridges. Other common beam profiles are the С-channel, the hollow structural section beam, the pipe, and the angle.
6. There are some reinforced concrete beams that are entirely in compression. These beams are known as prestressed concrete beams, and are fabricated to produce a compression more than the expected tension under loading conditions. High strength steel tendons are stretched while the beam is cast over them. Then, when the concrete has begun to cure, the tendons are released and the beam is immediately under eccentric axial loads. This eccentric loading creates an internal moment, and, in turn, increases the moment carrying capacity of the beam. They are commonly used on highway bridges.
7. Mathematical methods for determining the beam forces (internal forces of the beam and the forces that are imposed on the beam support) include the moment distribution method, the force or flexibility method and the direct stiffness method.

1. A second top plate usually laps the first plate at the comers and partition intersections and, when nailed in place, provides an additional tie to the framed walls.
2. A multi ple-stud post made up of at least three studs is generally used at exterior comers and intersections to secure a good tie between adjoining walls and to provide nailing support for the interior finish and exterior sheathing.
3. Studs, wall plates and lintels serve as a nailing base for all covering material and support the upper floor platforms, which provide the lateral strength along a wall.
4. Lintels are usually constructed of two pieces of lumber separated with spacers to the width of the studs and nailed together to form a single unit.
5. Nailing supportfor the edges of the ceiling is required at the junction of the wall and ceiling where partitions run parallel to the ceiling joists.
6. Studs, wall plates and lintels serve as a nailing base for all covering material and support the upper floors, ceiling and roof.
7. They are supported on a bottom plate or foundation sill and in turn support the top plate. Interior partitions supporting floor, ceiling or roof loads are called loadbearing walls; others are called non-loadbearing or simply partitions. Interior loadbearing walls are framed in the same way as exterior walls.
8. There are three historically common methods of framing a house.
9. The top and bottom plates are end-nailed to each stud with two nails.
10. Once the assembled sections are plumbed, they are nailed together at the corners and intersections.
Framing is a building technique based on structural members which provide a stable frame to which interior and exterior wall coverings are attached and covered by a roof comprising horizontal ceiling joists and sloping rafters (together forming a truss structure) or manufactured pre-fabricated roof trusses — all of which are covered by various sheathing materials to give weather resistance.
Wall framing in house construction includes the vertical and horizontal members of exterior walls and interior partitions, both of bearing walls and non-bearing walls. _. The platforms may be the boxed structure of a ceiling and roof, or the ceiling and floor joists of the storey above. _.
Post and beam framing is now used in bam construction.
Balloon framing using a technique suspending floors from the walls was common until the late 1940s, but since that time platform framing has become the predominant form of house construction.
Platform framing often forms wall sections horizontally on the sub-floor prior to erection, easing positioning of studs and increasing accuracy while cutting the necessary manpower. _. Studs are at least doubled at openings, the jack stud being cut to receive the lintels (headers) that are placed and end-nailed through the outer studs.
Wall sheathing, usually a plywood or other laminate, is usually applied to the framing prior to erection, thus eliminating the need to scaffold. _. Corners and intersections, however, must be framed with at least two studs. _.
Wall framing in house construction includes the vertical and horizontal members of exterior walls and interior partitions. _.
Exterior wall studs are the vertical members to which the wall sheathing and cladding are attached. _.
Lintels (headers) are the horizontal members placed over window, door and other openings to carry loads to the adjoining studs. _. The preferable spacer material is rigid insulation.
The complete wall sections are then raised and put in place, temporary braces added and the bottom plates nailed through the subfloor to the floor framing members. _.A strip of polyethylene is often placed between the interior walls and the exterior wall, and above the first top plate of interior walls before the second top plate is applied to attain continuity of the air barrier when polyethylene is serving this function. _.

12.4 Прочитай и письменно переведи текст ENGINEERING FOR BUILDINGS:
Structural engineering is a field of engineering dealing with the analysis and design of structures that support or resist loads. Structural engineering is usually considered a specialty within civil engineering, but it can also be studied in its own right.
Structural engineers are most commonly involved in the design of buildings and large nonbuilding structures but they can also be involved in the design of machineiy, medical equipment, vehicles or any item where structural integrity affects function or safety of the item. Structural engineers must ensure their designs satisfy given design criteria, predicated on safety (e.g. structures must not collapse without due warning) or serviceability and performance (e.g. building sway must not cause discomfort to the occupants).
Structural engineering theory is based upon physical laws and empirical knowledge of the structural performance of different landscapes and materials. Structural engineering design utilises a relatively small number of basic structural elements to build up structural systems that can be very complex. Structural engineers are responsible for making creative and efficient use of funds, structural elements and materials to achieve these goals.
Structural engineering has existed since humans first started to construct their own structures. It dates back to at least 2700 BC when the step pyramid for Pharaoh Djoser was built by Imhotep, the first engineer in history known by name. Pyramids were the most common major structures built by ancient civilizations because the structural form of a pyramid is inherently stable and can be almost infinitely scaled (as opposed to most other structural forms which cannot be linearly increased in size in proportion to increased loads).
Throughout ancient and medieval history most architectural design and construction were carried out by artisans, such as stone masons and carpenters, rising to the role of master builder. No theory of structures existed, and the understanding of how structures stood up was extremely limited and based almost entirely on empirical evidence of “what had worked before”. Knowledge was retained by guilds and seldom supplanted by advances. Structures were repetitive, and increases in scale were incremental.
No record exists of the first calculations of the strength of structural members or the behaviour of structural material, but the profession of a structural engineer only really took shape with the industrial revolution and the re-invention of concrete. The physical sciences underlying structural engineering began to be understood in the Renaissance and have been developing ever since.
Structural engineering became a more defined profession with the Burj Khalifa in Dubai, the emergence of the architecture world's tallest building. profession as distinct from the engineering profession during the industrial revolution in the late 19th century. Until then, the architect and the structural engineer were often one and the same — the master builder. Only with the understanding of structural theories that emerged during the 19th and 20th centuries the professional structural engineer came into existence.
The role of a structural engineer today involves a significant understanding of both static and dynamic loading, and the structures that are available to resist them. The complexity of modem structures often requires a great deal of creativity from the engineer in order to ensure the structures support and resist the loads they are subjected to. A structural engineer will typically have a four or five year undergraduate degree followed by a minimum of three years of professional practice before being considered fully qualified.
Structural engineers are licensed or accredited by different learned societies and regulatory bodies around the world (for example, the Institution of Structural Engineers in the UK).
