ANALYSES OF MECHANICAL BEHAVIORS OF MULTI-RIBBED COMPOSITE WALL WITH OPENING
Based on the previous studies of the test of a 1/2 - scaled multi-ribbed composite wall with opening under monotone horizontal load in contrast with one without opening, this paper are devoted to fulfilling the following points on the wall with opening: studying the main failure patterns; discussing the mechanical behaviors such as bearing capacity, rigidity, distortion capacity, ductility and so on; analyzing the strain; finally, the formulas of rigidity and shear-bearing capacity are deduced. It can be concluded as follows: the distortion capacity and ductility of the wall with opening are better than those of the wall without opening, but the rigidity and shear-bearing capacity of the wall with opening are much less than those of the wall without opening. So the steel bars of outer frame columns and connecting beams, and the vertical connection of walls should be strengthened. Strain analysis shows that the outer frame columns and the connecting beams play a more important role in the mechanical behaviors of the wall with opening. The value concluded from the shear-bearing capacity formula is approximate to the experimental result, and can be applied to the practical engineering.
