Abstract

Two types of corrugated steel plate shear walls, namely low-yield point (LYP) and convention, are investigated in terms of strengthening reinforced concrete (RC) frames. Within LYP corrugated steel plate shear walls, two layouts are considered: half and full plate. A total of 24 models are considered to assess their performance in the aspect of ultimate strength, stiffness, and mechanical analysis. The objective of this research is to compare and analyze the effectiveness of LYP corrugated steel plate shear walls in enhancing the seismic resistance of RC frames. Based on force analysis and finite element modelling, the equivalent support model is proposed to verify the validity of the models. The deviation was between 1.76 and 14.27%. The findings reveal that LYP corrugated steel plate shear walls demonstrate comparable bearing capacity to conventional methods, with the added advantage of improved ductility. The maximum top displacement increases by 35% and 68% in the case of half and full plate. Although there is minimal variation (9.86%) in stiffness, these characteristics collectively contribute to enhanced seismic resistance and overall performance of the reinforced concrete frames.

低屈服点波纹钢板剪力墙在加固钢筋混凝土框架中的行为
本文从加固钢筋混凝土(RC)框架的角度研究了两种波形钢板剪力墙,即低屈服点(LYP)和常规剪力墙。在 LYP 波形钢板剪力墙中,考虑了两种布局:半板和全板。共考虑了 24 个模型,以评估它们在极限强度、刚度和力学分析方面的性能。本研究的目的是比较和分析 LYP 波纹钢板剪力墙在增强 RC 框架抗震性方面的有效性。在受力分析和有限元建模的基础上,提出了等效支撑模型来验证模型的有效性。结果表明,LYP 钢板剪力墙的抗震性能与钢筋混凝土框架的抗震性能之间存在一定的偏差,偏差在 1.76% 到 14.27% 之间。研究结果表明,LYP 波纹钢板剪力墙的承载能力与传统方法相当,而且还具有延展性更好的优点。半板和全板的最大顶部位移分别增加了 35% 和 68%。虽然刚度变化极小(9.86%),但这些特点共同增强了钢筋混凝土框架的抗震性和整体性能。
