我们到唐山等地震区,调查了砖壳体(非金属油罐)的震害和抗震加固经验,提出了抗震设计应注意的技术问题和构造处理方案、抗震简化近似计算及加固修复的建议,可供砖壳体设计、施工参考。一、震害情况调查了容量大干100米~3的38个非金属油罐,其结构由钢筋混凝土圆形底板,砖筒壳罐壁和圆形底球面扁壳的罐顶组成(图1)。
We went to Tangshan and other earthquake areas to investigate the earthquake damage and seismic reinforcement experience of brick shells (non-metallic oil tanks), and put forward technical problems and structural treatment solutions that should be paid attention to in seismic design, earthquake-resilient simplified approximate calculations, and proposals for reinforcement and repair. For brick shell design, construction reference. First, the damage situation The investigation of the 38 non-metallic oil tanks with a capacity of 100 meters to 3 meters, the structure of which consists of a reinforced concrete circular floor, brick shell tank wall and round bottom spherical shell tank top (Figure 1 ).
