［摘要］基于4個高強混凝土剪力墻試件抗震性能的試驗結(jié)果，將ABAQUS軟件提供的混凝土損傷塑性模型參數(shù)與已有的混凝土本構(gòu)關(guān)系結(jié)合起來，在基于能量等效原理的基礎(chǔ)上引入損傷因子概念，模擬其加載全過程和受力性能，模擬曲線與試驗曲線吻合較好。在此基礎(chǔ)上，分析了影響高強混凝土剪力墻變形能力的主要因素，包括混凝土強度、豎向分布鋼筋配筋率、水平分布鋼筋配筋率、邊柱箍筋體積配箍率、邊柱縱筋配筋率、軸壓比和剪跨比，并與試驗結(jié)果進行了對比。

Abstract:The experiments on seismic performances of 4 high-strength concrete shear walls(HSCW) were carried out. Based on the experimental results, the damage plasticity model parameters provided by the finite element software ABAQUS were combined with concrete constitutive relationship and damage factor was introduced based on the energy equivalence principle. The nonlinear analysis was performed to simulate the complete loading process and mechanical behaviors. The analysis results and experimental results matched well. Based on the analysis, the main factors that affect the deformability of high-strength concrete shear walls were studied, including concrete strength, reinforcement ratio with vertical and horizontal rebar distribution, stirrup volumn ratio with side columns, reinforcement ratio with side columns, axial compression ratio and shear-span ratio. The analysis results were compared with experimental results.
Keywords:high-strength concrete shear wall; performance-based design; deformability; nonlinear analysis; damage constitutive relationship
