摘　　要：为了提高废弃玻璃的利用率,拓展其在建筑领域的应用,将废弃玻璃研磨成粉代替石英砂制备蒸压加气混凝土砌块,进而开展了废玻璃蒸压加气混凝土砌体墙的抗震性能试验研究和有限元分析。对4片废玻璃蒸压加气混凝土砌体墙进行了3因素(高宽比、竖向压应力、砂浆强度)的正交拟静力试验,试验结果表明:废玻璃蒸压加气混凝土砌体墙的破坏模式为剪切破坏;添加玻璃粉可以显著提高墙体延性,废玻璃蒸压加气混凝土砌体墙的位移延性系数在4.74~6.00之间,墙体的抗震性能良好。通过数值模拟分析发现,适当增加竖向应力、减小高宽比、提高砂浆强度均能够提升墙体受剪性能,其中高宽比的影响程度最大。In this paper,to improve the utilization rate of waste glass and expand its application in the field of construction,waste glass was ground into powder to replace quartz sand in the preparation of autoclaved aerated concrete blocks.Experimental research and finite element analysis were conducted on the seismic performance of waste glass autoclaved aerated concrete masonry walls.An orthogonal quasi-static test was designed for four walls made of waste glass autoclaved aerated concrete masonry,considering three factors:height-width ratio,vertical compressive stress,and mortar strength.It is shown from the tests that the failure mode of waste glass autoclaved aerated concrete masonry walls is shear failure.The ductility is significantly improved by the addition of glass powder,with the ductility coefficient of waste glass autoclaved aerated concrete masonry walls ranging from 4.74 to 6.00,demonstrating good seismic performance.It is shown from the numerical simulation that the shear resistance of the walls can be improved by increasing vertical stress,reducing the height-width ratio,and improving mortar strength.Among these factors,the height-width ratio is found to have the greatest influence.
