Description
technical field [0001] The invention belongs to the technical field of building load testing, in particular to an actual load testing method of a super high-rise steel-concrete composite structure. Background technique [0002] In foreign countries, Jayasinghe and Jayasena analyzed the vertical deformation of multiple high-rise reinforced concrete frame-shear wall structures, and proposed a simplified prediction method and limit value for the vertical deformation difference according to different humidity. [0003] In China, in the 1990s, Wang Furun first proposed two methods to calculate the vertical deformation of high-rise building structures using the empirical formula and the integral formula. The integral formula is calculated using the shrinkage and creep model. Wang Jianmin analyzed the influence of structural vertical deformation difference on high-rise buildings caused by factors such as concrete elastic deformation, creep, shrinkage and temperature stress, and pro...
