在墙体上开洞,会改变墙体结构的力学性能,使得对其进行研究与设计时更加复杂。墙体的承载力和刚度,会受到墙体上开洞、以及附近有关构件的影响。曾经有研究人员对混凝土砌体剪力墙上开洞,对墙体性能产生的影响进行过一些研究,但大多数试验对象都只有一层。本文使用混凝土空心砌块砌筑了六片三层高、分别带有门洞口和窗洞口的1/2比例缩小墙体试件模型,以此为研究对象,探讨开洞对墙体性能产生的影响,并介绍所取得的初步研究成果。本文所述试验的主要目的:研究在循环荷载作用下,在部分灌芯配筋砌块砌体墙上开洞,对墙体性能所产生的影响。共在试验室制作了六片墙体试件,其中三片为带门洞口的墙片,另三片为带窗洞口的墙片。试验中发现:这些墙体试件的承载能力逐渐下降,最后会发生受剪破坏。本文认为,使得试件能够呈现类似框架结构的力学行为,得益于在墙体试件顶部所设置的砌块系梁构造。试验过程中出现砂浆水平裂缝、对角型破坏,均表明试件是受剪破坏。 Opening a hole in a wall will change the mechanical properties of the wall structure, making it more complicated to study and design. Wall bearing capacity and stiffness, will be affected by the hole in the wall, and the related components in the vicinity. There have been some researchers on the concrete masonry shear wall openings, the wall performance had some research, but most of the test object has only one layer. In this paper, six hollow concrete blocks were used to construct six half-scale wall specimens with three-storey height and with door openings and window openings respectively. The model was used as the research object to investigate the influence of the opening on the wall performance Influence, and introduce the preliminary research results achieved. The main purpose of the experiment described in this paper is to study the influence of open hole on the partial masonry reinforced block masonry walls under cyclic loading to the wall performance. A total of six wall specimens were made in the laboratory, of which three were wall pieces with door openings and the other three were wall pieces with window openings. It is found in the experiment that the carrying capacity of these wall specimens gradually decreases and eventually the shear damage occurs. In this paper, it is considered that the specimen can exhibit the mechanical behavior similar to the frame structure, thanks to the block beam structure set on the top of the wall specimen. During the test, mortar horizontal cracks and diagonal destruction occurred, all of which indicated that the specimens were damaged by shearing.
