【摘要】 为了了解空斗墙建筑在地震作用下的抗震性能,通过MTS加载系统对空斗墙片墙的抗侧力性能进行了伪静力试验,研究了不同砌筑方法和不同构造措施下空斗墙片墙在水平和垂直作用下初始裂缝的开展部位、裂缝形态、发展规律和墙体破坏机制,得到了不同空斗墙片墙的开裂荷载和极限荷载,为确定经济有效的空斗墙片墙构造措施提供试验依据。试验结果表明,采用构造柱加拉结筋或采用构造柱加水平钢筋混凝土带的空斗片墙,无论开裂荷载还是极限荷载都较无构造措施的空斗片墙有较大提高,可使空斗墙表现出良好的延性,而无加固措施的空斗墙,其脆性十分明显。更多还原

【Abstract】 Based on pseudo-static test of rowlock wall with different constructional measures by MTS loading system,the position of initial crack,distribution of crack,cracking load,failure load and failure state were studied,in order to provide test basis for the determination of economical and effective construction measures for rowlock wall.The test results show that the cracking load and failure load of rowlock wall reinforced with constructional column and tie bar,or with constructional column and horizontal reinforced concrete band,are increased significantly compared with rowlock wall without reinforcement measure.The reinforced rowlock wall has better ductility,whereas rowlock walls without reinforcement measure show obvious brittleness.更多还原
