Abstract:An office building in Lenovo Beijing Campus adopts the structural system of concentrically braced steel frame. It has many horizontal and vertical irregular items. Response spectrum analysis and elastic time-history analysis under frequently occurred earthquakes were conducted using SATWE and MIDAS respectively. Comfort degree evaluation was conducted on large-span trusses induced by human walking excitation. Dynamic elastic-plastic time-history analysis under rare earthquakes was conducted using ABAQUS software. Calculating results show that the structure has good seismic performance.
Keywords:concentrically braced steel frame; elastic time-history analysis; human walking excitation; comfort degree evaluation; dynamic elastic-plastic time-history analysis
