摘    要:对低强度砂浆砖砌体墙片经过剪刀撑水泥砂浆网薄层加固后,与未加固砌体墙片在相同竖向压应力下进行拟静力对比试验。试验结果表明,对于砂浆强度很低的砌体,剪刀撑水泥砂浆网薄层加固能有效增强砌体的抗震性能,其极限荷载、极限位移、抗侧刚度均比未加固墙体有明显提高,延性比有所降低。在此基础上讨论了剪刀撑水泥砂浆网薄层加固砌体结构墙体的抗剪承载力计算模型,并提出了抗剪承载力建议公式,公式值与试验值符合较好。结论可为公程设计人员提供参考依据。

关 键 词:水泥砂浆  加固  砖砌体  拟静力  极限荷载

Abstract:Comparative test between low-strength mortar masonry wall strengthened with X-brace ferrocement laminate and non-reinforced masonry wall is put up.The test proves that X-brace ferrocement laminating can increase the seismic resistant capacity of the wall effectively.This method of reinforcement also improves the wall's ultimate load,ultimate displacement,and lateral stiffness of the wall.However,the performance of X-brace ferrocement laminate working together with the original wall is satisfactory.The formu...
