圈梁在抗震设计中的作用,经过海城、唐山地震的考验,已被大多数人所认识。但在设计和施工实践中,仍存在圈梁设置不当等问题。现就抗震圈梁的作用和设置谈一些个人的看法和体会,以供参考。一、圈梁在砖石和大型砌块建筑中的抗震作用1.加强楼层的整体刚度一般楼层均由预制板铺成,整体性较差,地震时,容易互相错动,不能把地震力有效地传到横墙上,尤其在横墙布置不均匀对称、地震时产生扭转
The role of ring beams in seismic design has been recognized by most people after the tests of the Haicheng and Tangshan earthquakes. However, in the design and construction practice, there are still problems such as improper setting of the ring beams. Let us talk about some personal views and experiences on the role and setup of anti-vibration beams. I. Anti-seismic effect of ring beams in masonry and large-scale block buildings 1. Strengthen the overall stiffness of floors The general floors are all paved with prefabricated plates and the overall integrity is poor. In an earthquake, they are easily misaligned with each other and seismic forces cannot be effectively used. It is transmitted to the horizontal wall, especially when the horizontal wall is unevenly symmetrical and the earthquake is twisted.
