Behavior of the Tube-gusset Connection Using 600MPa High-strength Steel

摘要

While the recent high demand for high rising buildings has led to the development of high-performance and high strength steels, the requirements for structural-performance steel for building have been raised as engineers recog nize the potential damage that an earthquake can wreak on a tall building. Many studies on high-strength steels have explored such need, but in case of hollow section, appropriate design equations are needed because the design equations limit the maximum yield stress up to 360MPa in the design code KBC 2009. This study is carried out the experiment test on strength of tube-gusset connection. It is also performed to investigate the behavior and strength of tube-gusset connection through comparing the experimental results and FEA using 600MPa circular hollow. This study analyses tube-gusset connection applied moment &- shear force and compares experimental values with analyt ical values for evaluating the applicability of current design equations. Current design equation is estimated to 68% ～129%.
