摘要：The paper focuses on the value of the foundation's rotation of the light steel portal-rigid frames which is caused by the upper uneven loads .It analyzes the effect of the rotation of the foundation on the internal force of the upper structure. It calculates the values of the rotation and the influence to the internal force of the upper structure respectively under four different load conditions which are constant load, live load, wind load, and crane load. It draws a conclusion that the additional internal force which is caused by the rotation of the foundation is large. If not consider the effect in the design, the structure is unsafe. © (2011) Trans Tech Publications, Switzerland.
