摘要：
This paper describes a method of analysis for dynamic behavior of multistory frames, in particular the natural frequencies and modal shapes that could be developed to study the effects of forced vibration. It is shown how composite stiffening effects of walls and floors can be introduced into the design, which highlights the need for more tests in real buildings.
