Slab-foundation is one of popular styles of foundation in frames,which features slab system without girder, specific mechanics, excellent structural stiffness and easiness in construction. Based on analysis and comparison between the method of equivalent frames and the method of practical experience factor design,a new design method of moment factor in equivalent beam for slab foundation is obtained. Combined with the new codes, the formulas of simplified calculation and requirement, including the calculation of punching, shear, flexural and design for reinforcement, are presented for practice. The calculation charts for design are also given.
