The analysis for a structure with more triangular elements will be also similar. The Method of Joints. Draw the Draw the free-body diagram of a joint with one or two with one or two unknowns. Truss The three methods to solve a truss are: 1. The graphical analysis was developed by force polygons drawn to scale for each joint, and then the forces in each member were measured from one of these force polygons.

Further in case weight of individual member is to be taken into consideration, half of them are to be distributed at each of the pinned ends. 3.Graphical Method of Truss Analysis (Maxwell’s Diagram) The method of joints could be used as the basis for a graphical analysis of trusses. In this section it will be analyzed a simple Warren truss created with five . If the support reactionsare not given, draw a FBD of the entire truss and determine all the support reactions using the equations of equilibrium. Historically, graphical solutions for truss systems, cables and arches have been used for a variety of design problems. Analysis of Trusses The analysis of trusses is usually based on the following simplifying assumptions: •The centroidal axis of each member coincides with the line connecting the centers of the adjacent members and the members only carry axial force. INTRODUCTION Our project involves analysis and design of Truss using a very popular designing software STAAD Pro. 4.1 Types of truss Generally the form selected for a truss depends upon the purpose for which it is required. Graphical analysis methods for trusses are divided into the method of joints and method of moments. Figure below shows a sample truss. There are two problems for designing of truss nodes sheets: dimensions of a sheet and hidden lines of a sheet. There simple easy and quick way to solve the truss for graphical method! We have chosen STAAD Pro because of its following advantages: 1) easy to use interface, 2) conformation with the Indian Standard Codes, 3) versatile nature of solving any type of problem, 4) Accuracy of the solution. �C^T�g��mͳ0�
