一、问题的提出 在静力作用下,对灰砂砖墙体进行了大量的试验研究。但对灰砂砖墙体的振动台试验国内还没有做过。由于仅仅通过静力和伪静力试验还不足以判断灰砂砖墙体在地震激励下的性能,故有必要进行模拟地震的振动台试验,通过本次试验希望能解决下列问题: 1.在地震作用下,灰砂砖实体墙和开洞 I. Proposal of the problem Under the static effect, a large number of experimental studies have been conducted on the lime sand brick wall. However, shaking table tests for sand-lime brick wall have not been done in China. Since static and pseudo-static tests alone are not sufficient to determine the performance of sand-lime brick walls under seismic excitation, it is necessary to carry out shaking table tests for simulated earthquakes. Through this test, it is hoped that the following problems can be solved: Under the action of earthquake, solid walls and openings in sand-lime bricks
