砖是我国多层砌体房屋的主要建筑材料,由于现在生产的灰砂砖虽然在几何尺寸上同粘土砖相同,单砖的抗压、抗折性能也接近粘土砖,但灰砂砖表面光滑、吸水性显著不同于粘土砖,灰砂砖墙体的抗震性能应如何正确评价还未深入进行。本文共进行了8片灰砂砖墙体(包括不同试件形式、不同砂浆标号和不同垂直应力)在低周反复荷载作用 Brick is the main building material of multi-storey masonry houses in China. Although the sand and lime bricks produced are the same in geometry as clay bricks, the compressive and flexural properties of single bricks are similar to that of clay bricks, but the surface of sand and lime bricks is smooth. The water absorption is significantly different from that of clay bricks. The correct evaluation of the seismic performance of the lime sand brick wall has not yet been carried out. In this paper, eight litho-sand brick masonry structures (including different specimen forms, different mortar labels, and different vertical stresses) were subjected to low-cycle cyclic loading.
