Experiment on truss-to-box girder connection models of the Hefei Xinqiao International Airport Terminal
摘要
Abstract
In order to investigate the bearing behavior of the truss-to-box girder connections of the Hefei Xinqiao International Airport Terminal,two model experiments were carried out under static loading.The load-displacement curve and out-of-plane displacement were measured,as well as the strain at the concerned positions.The failure modes of the truss-to-box girder connections were obtained.Finite element analysis models were established.The bearing behavior of the connections was simulated and the results of experiments and FEA models were compared.The results show that the specimens are elastic state under the design load,and prove the design is reasonable and safe.The scaled model ZHJD-1 is in a brittle failure state with weld fracture,and the full scale model ZHJD-2 is with a compression buckling damage in the tube.The experiment results and FEA results agree well.The effects of different initial defects applied on the models are analyzed.The truss-to-box girder connection models are not sensitive to the initial defects.关键词
