Chapter 6 – Lecture 19
The main objective of chapter 6 is to use the equilibrium equations to analyze structures which are composed of pin-connected members.
Members are joined together by bolting or welding to a common plate (called guset plate)
Planar trusses lie in one plane ( i.e x-y plane). Forces acting on the joints and they lie in the same plane as the truss. That is why this type of trusses is considered as a two-dimensional truss.
To design a truss, it is necessary to find the force that will develop in each member at certain loading conditions. To do that, the following two assumptions are made:
TensionAssumptions for Design
Simple truss is constructed by starting with a basic triangular element such as the ABC truss below.
