摘　　要：都江堰中兴镇公立卫生院是"5.12"大地震灾后重建的重点建设工程之一,该工程为钢筋混凝土框架结构,其中的一个结构单元采用了倾斜角度为24o的坡屋顶结构。结合实际工程的设计,阐述了如何采用合理的空间计算程序对坡屋顶结构进行精确建模,并提出坡屋面结构所产生的水平推力对整体结构的影响不可忽略,且根据不同的结构布置,水平推力的影响程度会有大有小。实际工程设计时需多方案进行对比,以使结构设计安全、经济。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 of its 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 of the 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.

关 键 词：钢筋混凝土结构 坡屋面 结构建模 水平推力
