Description

technical field [0001] The invention relates to the technical field of component test measurement, in particular to a non-contact deformation measurement device for civil engineering steel structure test components. Background technique [0002] The prefabricated steel structure based on intelligence and industrialization can realize the industrialization of high-efficiency, high-quality, low-consumption, and low-emission engineering construction, which is the future development direction of China's construction. [0003] Compared with concrete structures, the load-carrying capacity of steel structures is more easily affected by the geometric properties of components and force deformation. In the design method of steel structure, two of the resistance coefficients are related to geometric properties and deformation, namely, geometric uncertainty and calculation uncertainty. In recent decades, the ability of computers to operate has been greatly improved, enabling the realiz...
