ANSYS finite element analysis software was used to simulate and study the influence of changing middle rib width and cavity edge angle on the structural strength of hollow block.The simulation results were compared and analyzed by experiments.The results show that when the width of the middle rib increases from 20 mm to 40 mm,the ultimate strength of the block increases by 33%;when the radius of the cavity edge angle increases from 0 to 15 mm,the compressive ultimate strength of the block can increase by 41....
