摘要
Abstract
The regulations and related contents regarding the minimum story shear for the seismic design of buildings issued in 'Code for seismic design of buildings' ( GB 50011-2010) were briefly described. A comparison between Chinese code and other seismic design codes was carried out. The necessity and applicability of the minimum story shear issued by all these codes were discussed. The calculated base shear of a structure may depend on some parameters, such as the seismic intensity, characteristic period of site, structural periods, modes and damping ratios, etc. The relation among the story shear factor and these parameters were described herein in this paper. The responses to earthquake action and wind load of structures which were of different heights or located in different seismic regions may differ from each other. Some of the key parameters calculated for the seismic design of tall buildings as examples were given to identify that the regulations of the minimum story shear are necessary and implementable for the seismic safety of tall buildings.关键词
