statically determinate trust analysis. Method of joints. In this lecture, I'm going to discuss the analysis of statically determinant trusses. The lecture addresses two main questions. What is a statically determinate trust and how do we analyse one? A trust structure is an interconnected network of slender members, each capable of carrying an axial force. Only the forces either compressive or 10 sile. Theoretically speaking, no sheer force or bending moment is present in trust members. Here are a few trust configurations usually seen in building roofs and bridges. How trust Warren Trust, Pratt Trusts and K Trust. Generally, we assumed trust members are connected to each other using frictionless pins. This means if we have to trust members that are joined together, one is free to rotate relative to the other. In other words, trust joints cannot resist any bending moment. Since neither the joints nor the members of a trust are designed to carry any bending moment. Applied loads need to be placed at the joints. On Lee, no load should be applied directly to a trust member. Here is a simple trust structure with five members
