Abstract
In order to study the seismic response regularity of the bi-directional beam string structure considering collaborative work of the upper and lower structures,time-procedure analysis method is used to analyze the seismic response on an 80 m × 80 m bi-directional beam string structure model.Under vertical seismic action,the seismic performance of the structure without the supporting frame and the performance of the structure with the same supporting frame but different supporting frame con-dition is compared and analyzed.Under vertical seismic action,the axial force of brace is almost the same with or without con-sidering the supporting frame,while the upper beam vertical displacement is increased with the supporting frame,and the sur-rounding of the roof even increases by several times;when supporting structure is the same but the supporting condition is dif-ferent,the force of brace axial and the vertical displacement of the winding beam are almost the same,but the horizontal dis-placement of the winding beam is of big difference under the vertical seismic acting;changing supporting condition only affects the order of the various vibration modes of the structure,but does not affect the structural vibration modes.The research result provides some reference for the seismic design of bi-directional beam string structure.关键词
