通过试验研究了4个用钢丝网水泥砂浆加固的砌体墙的平面外受力性能。结果表明,在集中荷载作用下,加固墙的破坏类型是冲切破坏;在均布荷载作用下,加固墙的破坏是由于砌体单元的弯拉破坏而破坏。最后在假设钢丝网水泥砂浆是线性应变硬化-理想塑性的复合材料的基础上,数值模拟了钢丝网水泥沙浆加固URM墙体的平面外受力性能,数值模拟结果与试验结果吻合较好。 The out-of-plane force performance of four masonry walls reinforced with wire mesh cement mortar was studied through experiments. The results show that under the action of concentrated load, the failure type of the reinforced wall is punching failure; under uniform load, the failure of the reinforced wall is destroyed by the bending failure of the masonry unit. Finally, based on the assumption that the wire mesh cement mortar is a linear strain hardening-ideal plastic composite, the out-plane mechanical behavior of the URM reinforced by steel mesh cement mortar is numerically simulated. The numerical simulation is in good agreement with the experimental results.
