Secondly this paper sets up the space finite element model of plane frame by the structural analysis software SAP2000 pares the calculation results between the plane formwork and the space formwork and analyzes the overall performance of space of the ultra high formwork support system.The results show that the calculation method of the plane formwork is relatively simple re...
