摘要
为科学保护福建土楼,针对在役损伤圆形土楼,以"庚庆楼"为土楼原型,取缩尺比例为1∶15,分别制作了带有水平施工缝、竖向干裂缝、窗台缝以及组合缝这四种损伤形式的土楼墙体缩尺模型。与无损伤土楼墙体缩尺模型进行对比,采用拟静力试验方法,研究在役损伤土楼墙体在地震荷载作用下的滞回曲线特征以及墙体的水平承载力、变形能力等。试验结果表明,水平施工缝对圆形土楼墙体的抗震性能影响最大,其次是竖向裂缝。
In order to scientifically protect the Fujian Tulou, aims at the damage of the circular earth building in service, with the “Gengqing Building” as the prototype of the earth building, the scale ratio of 1 ∶15 was taken, respectively, with horizontal construction joints, vertical dry cracks, window sill joints. And the combination of the four types of damage in the form of the soil wall scale model, compared with the scale model of the non-damaged soil wall, the quasi-static test method was used to study the hysteresis of the in-service damaged soil wall under seismic loading. Curve characteristics and the horizontal bearing capacity and deformability of the wall. The test results show that the horizontal construction joint has the greatest influence on the seismic performance of the original soil wall, followed by the vertical crack.
