Abstract
The roof trusses are mostly depended on the internal forces in the structure, dismember the structure and analyze separate free-body diagrams of individual members or combination of members. In this paper, the design of roof trusses frame, rivet diameters, and area of all members have to be calculated. General design theory of structural analysis, the equilibrium of rigid body, method of joints, tension and compression of members, mechanical properties of materials, design of riveted joints and area of trusses members in the project of Thilawa Zone (1) constructed by PREFAB STEEL Company Limited. This paper deals with the design and analysis of roof truss.
Highlights
A truss is a structure composed of several members joined at their ends so as to form a rigid body
Variations on the truss form are used in large machines
The 3D form of truss can be used to cover large areas without intermediate supports; this form is often used for large exhibition halls
Summary
A truss is a structure composed of several members joined at their ends so as to form a rigid body. They are used to span greater distances and to carry larger loads than can be done effectively by a single beam or column. They are of great importance to the engineer who is concerned with structures. They are commonly used to form bridges and to support roofs. In order to reduce these consequences (typically, the increase of the deflections), solutions are available such as use of pre-stressed bolts, or limiting the hole size. [1]
