In order to study the internal force and deformation characteristics of the cable net structure under static load,a scaled model specimen of Xi'an International Football Center was designed and fabricated according to the scale of 1∶10,and steppd static load tests were conducted on the upper half-span,right half-span and full-span of the model by using the new space structure water gravity lattice loading system with controlled loading step by step and DACS-Measure field measurement system.The test results show that:the new space structure lattice automatic synchronous loading system can achieve arbitrary proportional,multi-point synchronous and accurate loading,which is generally applicable to all kinds of space structure loading tests;under different loading modes,the vertical deformation of the cable net basically shows linear changes with increasing load,and the maximum deformation occurs at the edge of the hole of the cable net;the maximum cable force under the upper half-span load,the right half-span load and the full-span load are all located at the right of the central axis of the cable net.The research results can provide technical reference for the processing,manufacturing and construction application of similar cable net structures in China in the future.
