[關(guān)鍵詞] 大懸挑結(jié)構(gòu)；人行激勵；峰值加速度；自振模態(tài)

( Huasen Arclutecture & Engineering Design Consultants Ltd., Shenzhen 518054, China)Abstract: The museum of contemporary art and planning exhibition of Shenzhen is a complicated structure, including large cantilever steel truss. It is necessary to study the structural vibration induced by pedestrian incentive. In this paper, software MIDAS/Gen is used to study the veItical vibration mode, and then the vibration load induced by human walking is applied to get the resonant frequency and the corresponding acceleration peak value to evaluate the vibration comfort of the slab.
Keywords: cantilever truss; pedestrian incentive, acceleration peak value; vibration mode
