摘要
钢筋混凝土板柱结构是一种经济技术指标较优的常用建筑结构形式。相比于钢筋混凝土框架结构,未配置抗冲切钢筋板柱结构的抗侧刚度低,抗震性能差,这是因其节点的传力机制和冲切破坏导致的。多年来板柱结构的抗震性能研究已比较深入,但仍存在不足。文中就板柱结构抗震试验、等代框架模型非线性分析和抗震性能评估等方面介绍已有板柱结构抗震性能研究进展以及设计方法的发展现状,同时对已有成果和规范的设计方法进行总结、归纳及评析,为后续研究提供思路与方向,即需要明确板柱节点的冲切破坏机理,根据机理得到冲切破坏判断准则或计算公式并运用于非线性分析模型中,通过结构非线性分析为板柱结构抗震设计方法提供依据。
Reinforced concrete slab-column structure is a common architectural form with excellent economic and technical indicators. However, slab-column structure without shear reinforcements has low lateral stiffness and poor seismic performance compared with reinforced concrete frame, due to the force-transferring mechanism and punching shear of the slab-column connection. In the past decades, many research achievements about the seismic performance of slab-column structure have been made, but the research is still insufficient. The state-of-the-art on the seismic performance of slab-column structure and design method in terms of seismic experiment, nonlinear analysis of equivalent frame model and seismic evaluation is introduced in the paper. Meanwhile, the summary, generalization and comment for the achievement and design method is made to provide ideas for subsequent research. In subsequent research, mechanism of connection punching shear should be revealed. The punching shear criteria or formula should be obtained based on the mechanism and can be used in nonlinear analysis model. Seismic design procedures should be set up based on the data from the structural nonlinear analysis.
