摘　　要：对带吊车门式刚架轻钢结构厂房来说 ,由于厂房自重过轻造成基础偏心距过大 ,采用上部主刚架的控制工况组合设计基础难以满足其要求。通过对几个实例的基础反力的计算 ,分析了设计中遇到的问题及解决办法 ,详细阐述了轻钢结构厂房基础的控制工况 ,并对该类型基础的设计提供了一些切实可行的依据。One difficulty which will be met in the foundation design of portal frame light steel structure industrial building is the excessly large eccentricity due to the light dead weight,so that the normal method of foundation design will not satisfy all of the requirements.It is introduced that some problems and corresponding solutions in foundation design of the several practical projects the authors engaged.Considerations of selecting and optimizing the form of the foundation in the design of light steel structure industrial building is discussed in detail from the point of design steel cost.Some general principles of the foundation form selection and construction measures in foundation design are also presented.
