摘要(Abstract):

为研究泡沫微晶玻璃砖砌体的抗震性能,对5片泡沫微晶玻璃砖墙体进行了低周反复水平荷载下的拟静力试验。分析了泡沫微晶玻璃砖墙体的破坏形态、滞回曲线、延性、刚度退化、耗能、抗剪承载力等,并综合考虑和研究了高宽比、竖向压应力及构造柱等因素对泡沫微晶玻璃砖墙体抗震性能的影响。试验表明:高宽比对试验墙体的影响较小;一定范围内增大墙体的竖向压应力可有效提高墙体的抗剪承载力和水平极限位移,使墙体的滞回曲线更加饱满;设置构造柱,可显著提高墙体的抗剪承载力和耗能能力。在抗震设防区,泡沫微晶玻璃砖可以代替烧结黏土砖作为承重墙体材料使用。
In order to research the seismic behavior of the brickwork made of foam microcrystalline glass brick, pseudo-static test was carried out on five pieces of walls made of foam microcrystalline glass bricks under the low cycle level load. Analysis was carried out on the failure mode, hysteretic curve, ductility, rigidity degeneration, energy dissipation and shear strength, etc. of walls made of foam microcrystalline glass bricks. The influences from height-width ratio, vertical compress stress, constructional column and other factors on the seismic behavior of walls made of foam microcrystalline glass bricks were took into account and researched. The experiments indicate the follows: the height-width ratio has a little influence on the walls tested; enlarging vertical compress stress of the walls in certain range can effectively increase the shear strength and ultimate lateral displacement of the walls, thus making the hysteretic curve of the walls more rounded; arranging constructional columns can significantly increase the shear strength and energy-dissipating capacity of the walls. In earthquake fortification regions, foam microcrystalline glass bricks can replace the clay bricks as the bearing materials.
