Bridges. Bridges . A bridge is a structure built to span physical obstacles such as a body of water, valley, or road, for the purpose of providing passage over the obstacle. (Wikipedia). Bridge – design influences. Suspension Bridges. A suspension bridge is a type of bridge which is built by suspending the roadway from cables attached to a master cable which runs above the length of the bridge. . They are strong and lightweight. A body being squeezed. Forces. Compression. Tension. A body being stretched. Truss. A truss is composed of slender members joined together at their end points.. They are usually joined by welds or gusset plates.. Old name for linear optimization. Linear objective functions and constraints. Optimum always at boundary of . feasible domain. First solution algorithm, Simplex algorithm developed by George . Dantzig. Chapter 7. University of Engineering & Technology, Taxila. 1. Properties of Trusses. . Truss is a frame structure in which all the members have axial forces due to the following facts:. Members are arranged in triangles for stability.. Tacoma Narrows Bridge Collapse. “. Gallopin. .

ON TRUSS ROOF. . All the gravity or vertical loads acting on the building trusses are first calculated in terms of the loads acting per one square meter of the horizontally projected area (plan area) having the units kg/m. © 2012 Project Lead The Way, Inc.. Principles of Engineering. A body being squeezed. Compression. Tension. A body being stretched. Forces. A truss is composed of slender members joined together at their end points.. Methods of Analysis. 2. Method of Joints. Method of Sections. The method of joints utilizes the force equations of equilibrium for each joint. . Analysis normally begins at a joint where at least one force is known and not more than two forces are unknown for plane trusses (or not more than three forces are unknown for space trusses).
