(Shanghai Institute ofArchitectural Design&Research (Co., Ltd.), Shanghai 200041, China)Abstract: The hospital project of Dujiangyan City Zhongxing town is one of the important architecture projects after '5-12' earthquake. This project is a reinforced concrete frame structure. One ofits cells has a sloping roof whose sloping angle reaches 24 degree. This article will discuss about how to accurately model the sloping roof depend on a reasonable space-calculating programme. At the same time, this article also brings forward the plane force result from the sloping roof can not be ignored, and different structural design will bring out different result ofthe plane force. When you design a structure, we should compare this scheme with the other, and then we can find a safe and economical structural design.
Keywords: reinforced concrete structure; sloping roof; structural modeling; plane force
