| Claculate AB member
The general layout of the truss system is shown fig 2. The loads on the structure,including dead,live wind and earthquake loads have been determined for the building. For your convenience,the truss member forces have been calculated for all load cases individally. The critical web member AB (forces due to load,live ,wind and earthquake loads are given in the table below)is to be designed as a tension member. Using appropriate load factors, calculate the most critical load combination for member AB and proportion it. You are limited to using either single or double angle.A steel grade of 350W(Fy=350MPa and Fu =500MPa) will be used.The onnections are to be bolted using M20 bolts with 80mm spacing
(60mm at end), and assume four bolts along one guage line.
AB member,deadload=193KN,Live Load=348KN, Wind load=132KN ,Earthquake Load =87KN, ALL ARE AXIAL TENSION FORCES IN THE MEMBER
