对剪力墙结构中小跨高比连梁的抗震设计方法进行了分析。从小跨高比连梁的抗震性能和施工难度出发,本文优先推荐加大洞口以增大连梁跨高比的方法。如果必须采用小跨高比连梁,则首先选择双连梁、多连梁方案,其次可选择集中对角斜筋连梁。最后,根据混凝土结构的基本抗剪机理,本文提出了一种强化配筋连梁,可供工程设计参考。
The seismic design method of the beam with small span ratio in shear wall structure is analyzed. Starting from the seismic performance and construction difficulty of a beam with a high ratio of span to a beam, this paper gives priority to the method of increasing the hole width to increase the span ratio of the beam. If you have to use a small span ratio beam, the first choice of double beam, beam beam program, followed by the choice of diagonal beam with a diagonal beam. Finally, according to the basic shear mechanism of concrete structure, this paper presents a reinforced reinforced concrete beam, which can be used for engineering design reference.
