Abstract:The general FEA program ANSYS is used to analyze bearing capacity of concrete block composite wall with structural columns under the vertical load distributed equally. The influences of structural column's space, reinforcement ratio in column, story height and elasticity modulus of masonry on load distribution and load bearing capacity of composite wall are discussed, and the formulas of compressive capacity of concrete block composite wall with structural columns are proposed.
Keywords:concrete small hollow block; structural column; composite wall; compressive bearing capacity
