Method for analyzing compressive bearing capacity of stainless steel bar concrete column

The invention discloses a method for analyzing the compressive bearing capacity of a stainless steel bar concrete column. The method comprises the following steps: establishing a stainless steel bar concrete eccentric compression test and a stainless steel bar concrete eccentric compression bearing capacity mesoscopic numerical model; carrying out midspan position local microscopic modeling processing, numerical parameter supplementing, load and boundary constraint setting, normal section strain distribution observation, stainless steel bar concrete axis compression test establishment, columnmidspan area local microscopic modeling, mesoscopic material parameter determination, axis compression bearing capacity numerical calculation and numerical calculation result comparison. According tothe invention, a mesoscopic numerical simulation result and a macroscopic test result are integrated and analyzed; by establishing the mesoscopic numerical model of the stainless steel reinforced concrete axial compression mem
