摘要
配置抗剪锚栓是提高板柱节点的抗冲切性能与变形性能的有效手段,为研究抗剪锚栓对板柱节点抗冲切性能的影响规律,对带抗剪锚栓板柱节点抗冲切承载力的计算方法进行对比,建立了带抗剪锚栓板柱节点抗冲切性能分析的1/4结构模型,考虑不同锚栓高度、锚栓半径、锚栓布置方式、锚栓间距、锚栓强度等参数对板柱节点抗冲切性能与变形性能的影响。结果表明:增加锚栓高度、锚栓半径、锚栓强度、增加斜向锚栓(非正交方向)、减小锚栓间距均能提高板柱节点抗冲切承载力和延性性能,反之则降低,其中斜向锚栓(非正交方向)数量变化所产生的影响最为明显。提出了板柱结构中抗剪锚栓布置的优化设计建议,并给出合理的参数取值范围。
It is an effective method to improve the punching shear performance and deformation performance of slab-column connections by setting shear studs.In order to study the influence law of shear studs on the punching shear performance of slab-column connections,the calculation method of punching shear capacity of slab-column connections with shear studs were compared,a 1/4 structural model was established for the analysis of the punching shear performance of slab-column connections with shear studs,the effects of different parameters including studs height,studs radius,studs arrangement,studs spacing and studs strength on the punching shear performance and deformation performance of slab-column connections were considered.And the results indicate that increasing studs height,studs radius,studs strength,the number of oblique studs(non-orthogonal direction)and decreasing studs spacing can all improve the punching shear capacity and ductility of the slab-column connections,and vice versa.Among them,the influence of the change in the number of oblique studs(non-orthogonal direction)is the most obvious.The optimal design of shear studs arrangement in slab-column structure was proposed,and the reasonable parameter range was given.
