Analysis on Reinforcement of Statically Indeterminate Truss

Abstract

AbstractWith the slowdown of the urbanization rate and new buildings in China, the old houses have different degrees of safety problems. Therefore, the importance of reinforcement and reconstruction of old houses has become increasingly apparent. This paper intends to study statically indeterminate trusses in buildings. Based on the finite element analysis, the paper compares the influence of the method of increasing section area on the original truss structure by establishing the reconstruction scheme of the same statically indeterminate truss. The numerical simulation results show that the ultimate bearing capacity of the structure is increased to achieve the purpose of strengthening.
