2. The theory and experimental work of the inelastic deformation of the plate under the cyclic compressive load are introduced. Box-shaped welding square columns were used for testing, focusing on the influence of different initial deflections on the cyclic deformation properties of the plate members. A comparison of load-deformation performance between cyclic loading and monotonic loading is given.
