The pre-engineered building(PEB) construction has been gradually applied to single story buildings as a practical and efficient alternative to conventional buildings. However, there has been a few structure collapse due to suddenly excessive load. Although a structure design requires accurate and professional skills, the PEB system tends to be designed simply because of complexation of structural analysis for connections. This paper shows the finite element analysis(FEA) using ABAQUS software on bolted connection which was previously tested. The FEA condignly simulated the behavior of bolted connection in PEB system and was in close agreement with experimental results. Then the stiffness reduction factor of the bolted joints that can be used in the actual design is presented through the analysis of the joint parameters.

This study is experimental research for the effect of gap at the end plate on the performance of extended end-plate type splice. For this research, simple beam type specimens by using extended end-plate type splice are planned. Main variables are the initial gap between end-plates, the installation of finger shim plate before the installation of high tension bolts, the final gap between end-plates, and the installation of finger shim plate after the installation of high tension bolts. The static loading tests results show that the maximum bending strength of splice is not dependent on the gap, but the vertical displacement, initial stiffness and elastic stiffness are affected by the gap. In addition to that, the possibility of brittle fracture is increased when the torque of high tension bolt is used to control the gap. Thus, careful consideration is needed in this case.
