Comparative Study on Behavior of Truss Connections Using Bolt and Welding

Abstract

The object of this research was focused on comparative study on behavior of truss connections using bolt and welding of actual structure against finite element method program. The results of the study revealed that bolt strength of the trusses having connection with bolt and were less than the value from SAP2000 program by observing from the slope value of graphs applied load and deformation of trusses at mid-span. The trusses type 1 showed the slope value less than the program 57.77 percent and 74.39 percent for the bolting connection and welding connection respectively. The trusses type 2 showed the slope value less than the program 46.57 percent and 73.45 percent for the bolting connection and welding connection respectively. When compared the test results with the standard design ASD Method. it was found that safety factor of the trusses type 1, the average were 1.20 and 2.32 for bolting connection and welding connection respectively. For the trusses type 2, the average were 1.28 and 2.72 for bolting connection and welding connection respectively. The significant finding was showed that the connection by welding methods gave the safety factor value greater than bolting methods.
