Abstract: Common loading station building shape is mostly regular structures, with the development of industry and market. The process required to achieve the bottom column net less and the upper column net more,for the problems of the vertical lateral force resisting members discontinuity. Combined with the practice of Zhuhai design and application of loading station truss.,researching and analysing the force characteristics of conversion layer in the complex conditions of loading station .The results show that the design method is feasible and can provide reference and experience for similar engineering design.
