摘要
依据已有的关于小跨高比连梁配筋方案相关文献和研究成果,主要对布置交叉对角斜筋、菱形筋、纵筋的复合配筋方案和多层封闭约束箍筋两种方案进行了试验对比和有限元分析,研究了连梁的跨高比、箍筋和纵筋数量对其破坏形态、滞回性能、刚度退化、变形和耗能性能等的影响,并分析了构件的位移和荷载的关系,得出了一些结论。
In this paper,on the basis of the existing small span ratio of beam reinforcement scheme related literature and research achievements, mainly to decorate cross diagonal oblique muscle,diamond bar,longitudinal reinforcement of composite reinforcement scheme and the constraint of multilayer closed stirrup two test comparison research and finite element analysis,studied the cross coupling beam height ratio,number of stir-rups and longitudinal reinforcement to its failure pattern,hysteresis behavior,the influence of the rigidity degradation and deformation and energy dissipation properties,analysis of the relationship between the displacement and load component,and achieves some conclusion.
