摘要
将滑动隔震系统(SIS)与地面连接处用无阻尼可变刚度弹簧进行连接处理,研究 了建筑物的隔震层和基础板之间的停滑及滑动状态的转变过程,并利用外推法较精 确的判断了它们的转换时刻,且此时可采用大步长计算,节省计算费用。
To analyze structures with sliding supports, a fictitious spring model is used to simulate the sliding supports. Thus the structural responses can be obtained from the identical governing equation of the motion, either in sliding or non-sliding phase, and make it easier to analyze the nonlinear of structural moving. For exactly determining the transition time from the sliding to non-sliding phase to upgrade the precision and reducng the expenses of calculation, an extrapolating technique is used.
