摘 要: 结合一个工程实例,采用串并联质点系层模型分析了非对称连体结构的振动方程,讨论了连体位置在各楼层间发生变动时结构自振周期的变化规律,并对该结构体系沿连廊设置方向施加EL-Centro1940地震波,采用动力时程分析方法分析当连接体位置发生变化时该连体结构的抗震性能变化规律,得出了几点有用的结论以供实际工程应用参考。 Based on a practical engineering example, the vibrant equation of unsymmetrical connection structure is discussed through using series-parallel connection particle cluster layer model, the variational rule of structural self-vibration periods is analyzed when the connection position changes in every floors, and the connection directions EL-Centro1940 seismic wave are put in the structure. Dynamic Analysis Methods are used to analyis the variational rule of the structure seismis behavior when changes take place in the connectors, and some of the conclusions give useful reference for practical engineering applications.
