Abstract
Pin joints were adopted to connect the steel column and steel trusses of the second floor in long-span steel structure under heavy load in order to meet the requirement of ideal pin connection. The bar of steel truss is made of steel I-beam, which transitionally connect to the steel column by pin joints. But there is a problem that Design code for the steel structures (GB50017-2003) involves no design formula for pin joints, professional designers could only use foreign codes for reference which will lead to unsafe factors and waste of material. Therefore it is meaningful for us to do research on pin joints. In this case, Pin joint finite element model is built up by ABAQUS software ,and the process of tension, compression and cyclic loading are simulated to analysis the influence of load on bearing capacity. In conclusion, Pinned nodes are still in theirs flexibility under the design load and have good ductility under the failure load. The bearing performance of pinned joint meet the design requirements.
