Once the dimensional requirement for a structure have been defined, it becomes necessary to determine the loads the structure must support. Each system is constructed of one or more basic types of structures such as Trusses, Cables and Arches, Frames, and Surface Structures. Combination of structural elements and the materials from which they are composed is referred to as a structural system. Some of the structural elements are tie rods, rod, bar, angle, channel, beams, and columns. Other branches of engineering work on a wide variety of nonbuilding structures.Ĭlassification of structuresIt is important for a structural engineer to recognize the various types of elements composing a structure and to be able to classify structures as to their form and function. In order to design a structure, one must serve a specified function for public use, the engineer must account for its safety, aesthetics, and serviceability, while taking into consideration economic and environmental constraints.
Important examples related to Civil Engineering include buildings, bridges, and towers and in other branches of engineering, ship and aircraft frames, tanks, pressure vessels, mechanical systems, and electrical supporting structures are important. Structural analysis is thus a key part of the engineering design of structures.Ī structure refers to a body or system of connected parts used to support a load. The results of the analysis are used to verify a structure's fitness for use, often saving physical tests. Structural analysis incorporates the fields of applied mechanics, materials science and applied mathematics to compute a structure's deformations, internal forces, stresses, support reactions, accelerations, and stability. Structures subject to this type of analysis include all that must withstand loads, such as buildings, bridges, vehicles, machinery, furniture, attire, soil strata, prostheses and biological tissue. Structural analysis is the determination of the effects of loads on physical structures and their components.
