The roof structure of Ningjin gymnasium in Hebei Province is complex in shape and adopts a steel arch truss structure.MIDAS Gen software was used to conduct overall stability analysis and elastic calculation of the steel structure roof under frequent earthquakes.The analysis results show that the steel arch truss scheme is feasible and safe.Due to the large-span of the steel structure arch and the complex stress on the arch foot joints,four typical joints were selected for full-scale joint compression tests to verify the rationality and safety of the joint design.The experimental results show that the joints can withstand the load of the upper structure and leave appropriate safety reserves.
