Some problems such as the excessly large eccentrictity and corresponding solutions in foundation design of several practical project of portal frame light steel structure industrial building are introduced. 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.
