摘要
随着世界经济发展,城市全球化和全球城市化的进程日益加快,建筑行业在
其中发挥了无以比拟的作用,然而由于我国建筑业科技贡献率较低,仍属于高资
源消耗、高能耗、较高污染的粗放发展模式,建筑业大量消耗自然资源和产生大
量的筑垃圾严重恶化环境,使得其可持续发展面临着严重的问题。特别是在当前
资源节约型、环境保护型社会的创建中,寻找一种既能满足环保节能要求又满足
结构要求的新型砌体材料、降低建筑能耗和环境污染已成为建筑行业的一件大事。
在此情形下,一种节能、节土、利废,具有质轻、隔热保温、吸声隔音,抗震、
防火、可锯、可刨、可钉、施工简便和可增加建筑物使用面积等优点的新型墙体
材料——砂加气混凝土砌块的出现,为新型墙材的开发和应用提供了很好的机遇
和巨大的发展空间。
本文以砂加气混凝土砌块自保温墙体作为研究对象,分析了砂加气混凝土砌块
墙体自保温的基理,并从建筑抗震角度出发,对自保温墙体进行了水平低周反复
荷载试验,分析了不同高宽比、不同砌筑形式(普通砂浆砌筑、专用砂浆砌筑)
对墙体抗震性能的影响,用实验验证了其满足规范中规定的抗震要求。同时还在
试验的基础上,应用有限元软件 ANSYS 对砌体墙进行了非线性有限元数值模拟,
探讨了不同的影响因素对墙体的抗震影响。

Abstract
With the acceleration of urban globalization and global urbanization, construction
industry has played an irreplaceable role in the development of world economy.
However, since paratively speaking, contribute little to the industry,it
still belongs to extensive mode of development characterized by high energy
consumption, high resources consumption and large scale of pollution. Construction
industry degrades environment and endangers the strategy of sustainable development
by consuming large quantities of natural resources and producing construction waste.
Therefore, in the process of building a resource-saving, environmental-friendly society,
it is on top of the agenda of the construction industry to find a new construction material
that can both satisfy the needs of building a pollution-free society and meet the needs of
the construction structure. Under this circumstances, the emergence of a brand new wall
material—sand aerated concrete block, brings huge potential for the development and
application of the new type of wall material. The sand aerated block can save the energy,
land and make full use of the wasted. Besides, it also boasts many advantages such as
light mass, heat-insulation, sound absorption and seismic r
