SRC柱-钢梁混合框架直接基于位移的抗震设计方法研究
|
摘要
型钢混凝土(SRC)柱-钢梁混合框架结构具有较好的抗震性能,在大跨度结构及高层建筑中得以广泛应用,然而对于SRC柱-钢梁混合框架结构的抗震设计方法研究较少。根据SRC柱-钢梁混合框架结构的特点,将其性能划分为使用良好、暂时使用、修复后使用、接近倒塌四个水平,采用层间位移角限值予以量化,并在此基础上提出SRC柱-钢梁混合框架直接基于位移的抗震设计方法。利用通用有限元软件ABAQUS中的PQ-FIBER模型对SRC柱-钢梁混合框架进行静力弹塑性分析,并采用已有的试验研究成果对PQ-FIBER模型的适用性进行了验证。采用此方法对某8层SRC柱-钢梁混合框架结构进行了设计,然后采用静力弹塑性分析法验证该方法的可行性,为SRC柱-钢梁混合框架结构直接基于位移的抗震设计方法提供一定依据。
The SRC column-steel beam hybrid frame structure has good seismic behavior, which is widely used in large span structures and high-rise buildings. However, few studies have been performed on seismic design of the SRC column-steel beam hybrid frame structures. According to the characteristics of the SRC column-steel beam hybrid frame structure, its seismic performance is divided into four levels, i.e., serviceability, temporary use, use after repair, and close to collapse. The four levels is quantified using the inter-story drift ratio limits, based on which the direct displacement-based seismic design method of SRC column-steel beam hybrid frame is proposed. The PQ-FIBER model in ABAQUS is used to analyze the static elasto-plastic performance of the SRC column-steel beam hybrid frame, and the applicability of the PQ-FIBER model is validated by the existing experimental results. Finally, the method has been successfully applied to an eight-storey SRC column-steel beam hybrid frame structure, and is validated by static elasto-plastic analysis. The proposed method herein can form a basis for the direct displacement-based seismic design of the SRC column-steel beam hybrid frame structure.
