摘要

陶粒泡沫混凝土（CFC）是一种轻质保温复合材料。本文创新性地提出了一种新型的中低层建筑陶粒泡沫混凝土组合剪力墙，该组合剪力墙采用CFC作为普通混凝土（NC）层之间的夹层。本文通过对6个CFCW试件和1个普通混凝土剪力墙试件进行恒轴压循环加载试验，首次对CFCW试件的抗震性能和破坏机理进行了研究。此外，夹层和实体边界单元均能有效提高CFCW试件的承载力、延性、刚度和耗能能力。提出并验证了CFCW试件抗弯承载力的理论计算方法。本文提出的CFCW具有可靠的抗震性能，为低层和中层建筑的设计提供了一种新的解决方案，在可持续建筑中具有很大的应用潜力。

Experimental study on seismic behaviour of precast composite shear wall with ceramsite foam concrete interlayer

Ceramsite foam concrete (CFC) is a lightweight insulating composite material. This study proposes a novel Ceramsite foam concrete composite shear wall for low-rise and mid-rise buildings, in which CFC is used as an interlayer between normal concrete (NC) layers innovatively. In this paper, the seismic performance and failure mechanism of CFCW are investigated for the first time through cyclic loading tests under constant axial compression on six CFCW specimens and one normal concrete shear wall (NCW) specimen. Further, both sandwich and solid boundary elements effectively enhance the bearing capacity, ductility, stiffness, and energy dissipation capacity of the CFCW specimens. A theoretical calculation method for the flexural load capacity of the CFCW specimens is proposed and validated. The CFCW proposed in this paper exhibits reliable seismic performance, providing a novel solution for the design of low-rise and mid-rise buildings and holding significant potential for application in sustainable construction.
