摘要:
含剪切型耗能梁段高强钢框筒结构(简称HSS-FTS-RSL)具有良好的抗侧、抗扭刚度以及耗能能力,为研究楼板组合效应对结构抗震性的影响,针对大震下楼板过早与裙梁脱开问题,提出了相应构造措施加以改善.采用ABAQUS建立HSS-FTS-RSL子结构模型进行滞回分析,以连接件构造措施、楼板厚度、混凝土强度和耗能梁段长度为参数,分析其对子结构滞回性能的影响规律.结果表明:设置T型连接件可以在裙梁错动位移较大时延缓栓钉从RC楼板中拔出,并且T型连接件腹板宜沿跨度方向布置; 考虑楼板组合效应可以提升结构的初始刚度和承载力,楼板越厚、混凝土强度越高以及耗能梁段越短,提升幅度越大,但楼板的存在会一定程度上限制耗能梁段的转角,从而影响耗能梁段的塑性发展; 基于分析结果,提出了设计建议:耗能梁段长度不宜过长也不宜过短,耗能梁段长度比取值范围宜在0.95～1.25内,在满足结构性能需求及连接件构造要求的前提下,尽量选择厚度较薄的楼板,且混凝土强度等级不宜超过C30.
Abstract:
High-strength steel frame tube structure with replaceable low yield point shear link(HSS-FTS-RLYPSL)has good lateral and torsional stiffness and energy dissipation capacity. To study the influence of RC slab combination effect on the seismic resistance behavior of the structure, the corresponding structural measures are put forward to improve the premature separation of the RC slab and the spandrel beam under rare earthquake. The HSS-FTS-RSL substructure model is established by ABAQUS for hysteretic anaysis, and the structural measures of connectors, the thickness of the RC slab, the concrete strength and the length of the shear link are used as parameters to analyze their influence on the hysteretic performance of the substructure. The results show that the setting of T-shape Connector can delay the pull-out of studs from RC slab when the displacement of spandrel beam is large, and the web plate of T-shape should be arranged along the span direction. Considering the RC slab combination effect can effectively improve the initial stiffness and bearing capacity of the structure, the thicker the RC slab, the higher the concrete strength and the shorter the shear link, the greater the lifting amplitude. However, the existence of the RC slab will limit the rotation angle of the shear link to a certain extent, thus affecting the plastic development of the shear link. Based on the analysis results, the design suggestions are put forward: the length of the shear link should not be too long or too short, and the length ratio of the shear link should be in the range of 0.95 ～ 1.25. On the premise of meeting the structural performance requirements and the structural requirements of the connector, and the thinner RC slab should be selected as far as possible, and the concrete strength grade should not exceed C30.
