圈梁是砖混房屋建筑中普遍采用的结构加固措施。圈梁不是独立的受力构件,它是作为砖石砌体的一部分承受应力的。因此其应力分布情况比较复杂,很难确定。但是圈梁可以大大增强建筑物的整体刚度和强度以抵抗不均匀沉陷和震动荷载的不利影响是毫无凝义的。在非抗震地区,圈梁往往都兼作门窗过梁,因而前一阶段在多层房屋建筑中 Ring beams are commonly used structural reinforcement measures in brick-concrete buildings. The ring beam is not an independent force member. It is used as a part of the masonry to withstand stress. Therefore, the stress distribution is relatively complex and difficult to determine. However, the ring beam can greatly enhance the overall stiffness and strength of the building to resist the adverse effects of uneven subsidence and shock loading. In non-seismic areas, ring beams are often double doors and windows, so the previous stage is in multi-storey house buildings.
