摘要
本文以连杆节间为界,分别按铁木辛哥(Timoshenko)梁建立剪力墙振动方程,按一般框架建立框架振动方程,由模态综合法建立整个框架一剪力墙结构的自由振动方程,并据此计算其自由振动.通过算例说明本文方法较为精确简便,可直接手算或在微机上运算.
In this paper, Frame-Shear wall structure is divided into frame substructure and shear wall substructure by cutting the connecting beams. The vibration equation for shear wall substructure is set up according to Timoshenko Cantilever beam. The vibration equation for frame substructure is set up according to frame structure. The mode synthesis technique is used to set up the free vibration equation of frame shear wall structure. A numerical example shows that our method is simpler and more precise.
