The performance characteristics commonly structural engineering pdf download interest structural engineering pdf download the design of structures are 1 stresses or stress resultants, such as axial forces, shear forces, and bending moments; 2 deflections; and 3 support reactions.
Thus, the analysis of a structure usually involves determination of these quantities as caused by a given loading condition. Since the dawn of history, structural engineering has been an essential part of human endeavour. However, it was not until about the middle of the seventeenth century that engineers began applying the knowledge of mechanics mathematics and science in designing structures. Earlier engineering structures were designed by trial and error and by using rules of thumb based on past experience.
The fact that some of the magnificent structures from earlier eras, such as Egyptian pyramids about b. Galileo Galilei — is generally considered to be the originator of the theory of structures. In his book entitled Two New Sciences, which was published inGalileo analysed the failure of some simple structures, including cantilever beams. In L. Navier — published a treatise on elastic behaviour of structures, which is considered to be the first textbook on the modern theory of structural engineering pdf download of materials.
The development of structural mechanics continued at a tremendous pace throughout the rest of the nineteenth century and into the first half of the twentieth, when most of the classical methods for the analysis of structures described in this text were developed, structural engineering pdf download. The important contributors of this period included B. Clapeyron —who formulated the three-moment equation for the analysis of continuous beams; J. Greene —who developed the moment-area method; H, structural engineering pdf download.
Muller-Breslau —who presented a principle for constructing influence lines; G. Maney —who developed the slope-deflection method, which is considered to be the precursor of the structural engineering pdf download stiffness method; and Hardy Cross —who developed the moment-distribution method in The moment-distribution method provided engineers with a simple iterative procedure for analyzing highly statically indeterminate structures.
This method, which was the most widely used by structural engineers during the period from about tocontributed significantly to their understanding of the behaviour of statically indeterminate frames.
Many structures designed during that period, such as high-rise buildings, would not have been possible without the availability of the moment distribution method. Structural engineering pdf download availability of computers in the s revolutionized structural analysis.
Because the computer could solve large systems of simultaneous equations, analyses that took days and sometimes weeks in the pre computer era could now be performed in seconds. The development of the current computer-oriented methods of structural analysis can be attributed to, among others, J, structural engineering pdf download.
Argyris, R. Clough, S. Livesley, H. Martin, M. Turner, E. Wilson, and O, structural engineering pdf download. Structural engineering is the science and art of planning, designing, and constructing safe and economical structures that will serve their intended purposes.
Structural analysis is an integral part of any structural engineering project, its function being the prediction of the performance of the proposed structure. As this diagram indicates, the process is an iterative structural engineering pdf download, and it generally consists of the following steps:. Planning Phase — The planning phase usually involves the establishment of the functional requirements of the proposed structure, the general layout and dimensions of the structure, consideration of the possible types of structures e.
This phase may also involve consideration of non-structural factors, such as aesthetics, environmental impact of the structure, and so on.
The outcome of this phase is usually a structural system that meets the structural engineering pdf download requirements and is expected to be the most economical. This phase is perhaps the most crucial one of the entire project and requires experience and knowledge of construction practices in addition to a thorough understanding of the behaviour of structures.
Preliminary Structural Design — In the preliminary structural design phase, the sizes of the various members of the structural system selected in the planning phase are estimated based on approximate analysis, past experience, and code requirements.
The member sizes thus selected are used in the next phase to estimate the weight of the structure. Estimation of Loads — Estimation of loads involves determination of all the loads that can be expected to act on the structure. Structural Analysis — In structural analysis, the values of the loads are used to carry out an analysis of the structure in order to determine the stresses or stress resultants in the members and the deflections at various points of the structure.
Safety and Serviceability — Checks The results of the analysis are used to determine whether or not the structure satisfies the safety and serviceability requirements of the design codes.
If these requirements are satisfied, then the design drawings and the construction specifications are prepared, and the construction phase begins. Revised Structural — Design If the code requirements are not satisfied, then the member sizes are revised, and phases 3 through 5 are repeated until all the safety and serviceability requirements are satisfied.
Commonly used structures can be classified into five basic categories, depending structural engineering pdf download the type of primary stresses that may develop in their members under major design loads. The members of tension structures are subjected to pure tension under the action of external loads. Because the tensile stress is distributed uniformly over the cross-sectional areas of members, the material of such a structure is utilized in the most efficient manner.
Tension structures composed of flexible steel cables are frequently employed to support bridges and long-span roofs. Because of their flexibility, cables have negligible bending stiffness and can develop only tension. Thus, under external loads, a cable adopts a shape that enables it to support the load by tensile forces alone. In other words, the shape of a cable changes as the loads acting on it change, structural engineering pdf download. In a suspension bridge, the roadway is suspended from two main cables by means of vertical hangers.
The main cables pass over a pair of towers and are anchored into solid rock or a concrete foundation at their ends. Because suspension bridges and other cable structures lack stiffness in lateral directions, they are susceptible to wind-induced oscillations. Bracing or stiffening systems are therefore provided to reduce such oscillations. Besides cable structures, other examples of tension structures include vertical rods used as hangers for example, to support balconies structural engineering pdf download tanks and membrane structures structural engineering pdf download as tents.
Structural engineering pdf download structures develop mainly compressive stresses under the action of external loads. Two common examples of such structures are columns and arches. Columns are straight members subjected to axially compressive loads. An arch is a curved structure, with a shape similar to that of an inverted cable. Such structures are frequently used to support bridges and long-span roofs.
Arches develop mainly compressive stresses when subjected to loads and are usually designed so that they will develop only compression under a major design loading. However, because arches are rigid and cannot change their shapes as can cables, other loading conditions usually produce secondary bending and shear stresses in these structures, which, if significant, should be considered in their designs.
Because compression structures are susceptible to buckling or instability, the possibility of such a failure should be considered in their designs; if necessary, adequate bracing must be provided to avoid such failures.
Trusses are composed of straight members connected at their ends by hinged connections to form a stable configuration. When the loads are applied to a truss only at the joints, its members either elongate or shorten. Thus, the members of an ideal truss are always either in uniform tension or in uniform compression. Real trusses are usually constructed by connecting members to gusset plates by bolted or welded connections, structural engineering pdf download.
Although the rigid joints thus formed cause some bending in the members of a truss when it is loaded, in most cases such secondary bending stresses are small, and the assumption of hinged joints yields satisfactory designs.
Trusses, because of their light weight and high strength, are among the most commonly used types of structures. Such structures are used in a variety of applications, ranging from supporting roofs of buildings to serving as support structures in space stations. Shear structures, such as reinforced concrete shear walls, are used in multi-storey buildings to reduce lateral movements due to wind loads and earthquake excitations.
Shear structures develop mainly in plane shear, with relatively small bending stresses under the action of external loads. Bending structures develop mainly bending stresses under the action of external loads. In some structures, the shear stresses associated with the changes in bending moments may also be significant and should be considered in their designs.
Some of the most commonly used structures, such as beams, rigid frames, slabs, and plates, can be classified as bending structures, structural engineering pdf download. A beam is a straight member that is loaded perpendicular to its longitudinal axis. Recall from previous courses on statics and mechanics of materials that the bending normal stress varies linearly over the depth of a beam from the maximum compressive stress at the fiber farthest from the neutral axis on the concave side of the bent beam to the maximum tensile stress at the outermost fiber on the convex side.
For example, in the case of a horizontal beam subjected to a vertically downward load, the bending stress varies from the maximum compressive stress at the top edge to the maximum tensile stress at the bottom edge of the beam.
To utilize the material of a beam cross section most efficiently under this varying stress distribution, the cross sections of beams are often I-shaped, with most of the material in the top and bottom flanges. The I-shaped cross sections are most effective in resisting bending moments. Rigid frames are composed of straight members connected together either by rigid moment-resisting connections or by hinged connections to form stable configurations.
Unlike trusses, which are subjected only to joint loads, the external loads on frames may be applied on the members as well as on the joints. The members of a rigid frame are, in general, subjected to bending moment, shear, and axial compression or tension under the action of external loads.
However, the design of horizontal members or beams of rectangular frames is often governed by bending and shear stresses only, since the axial forces in such members are usually small.
Frames, like trusses, are among the most commonly used types of structures. Structural steel and reinforced concrete frames are commonly used in multistorey buildings, bridges, and industrial plants.
Frames are also used as supporting structures in airplanes, ships, aerospace vehicles, and other aerospace and mechanical applications. Your email address will not be published. Table of Contents. Structural engineering pdf download of Structural Engineering Project.
