PPT-Calculating Truss Forces

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. How Forces Affect Different Types of Bridges. Forces on a Beam Bridge. Simplest design (girder bridge). Compression on top of the beam. Tension on bottom of beam. Middle part not much of either forces. 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.. Chapter 4 Analysis of Structure. Introduction. Structure – connected system of members designed to support loads safely or to transfer forces effectively. Analysis of structures involves analyzing the equilibrium of the entire structure, part of the structure, or an individual member. Licensed Electrical & Mechanical Engineer. BMayer@ChabotCollege.edu.

A . truss is considered to be a solid beam full of holes. A truss and beam behave similarly under the same live load.. The point of a truss is to disperse forces as far from the neutral axis as possible in order to resist deflection.. Licensed Electrical & Mechanical Engineer. BMayer@ChabotCollege.edu.

No member is continuous through a joint.. Bolted or welded connections are assumed to be pinned together. 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).
