Different from conventional facade having been studied, this cable nets. area is larger and deformation control is more difficult. Because the stainless steel cable' s stress relaxation is large and the technology of cable tensioning in aloft is difficult, the optimization design is needed for the cable nets structure. This paper has designed several optimization schemes by changing cable nets structure arrangement, and had contrast studies to the original scheme，including the analysis of internal force and deformation of the cable net structure， and also consider the local structure change that has influence on the performance of the structure. The results show that changing the cable material has low influence on the cable internal force and deformation of the cable net,but the influence is large when the cable net support arrangement is changed.

Taking one tall building-Fuzhou Shimao International Financial Center as an example，the installation procedure of the platform was described and numerical analysis results were presented.Comparison of the numerical analysis results to experimental tests further illustrated the performance of the platform and revealed the deficiencies of original design. Improving suggestions were put forward based on the study.

It is mainly designed for construction of the vertical core wall of tall buildings. Based on the practical application of this formwork system in engineering projects， this paper introduced the overall design concept of hanging rack in low-position jacking steel platform formwork system and the key control points during its installtion. The work in this paper provided references to the standardization and assemblability of rack system.
