FEM was employed to study frame-supported multi-ribbed wall beam under vertical load.Using the changes in performance parameters such as divided form of wall,the size of the side column and the ratio of in-filled block and multi-ribbed frame,the mechanism of frame-supported multi-ribbed wall beam and the influencing factors of the parameters of wall to the wall beam are studied.Which provides references for the optimization and engineering practice of frame-supported multi-ribbed wall.
