［摘要］以型鋼高性能混凝土剪力墻試驗(yàn)研究為基礎(chǔ)，采用有限元軟件ABAQUS建立了型鋼高性能混凝土剪力墻的非線性有限元模型，考慮材料非線性，模擬了加載全過程和混凝土開裂等受力性能，數(shù)值計(jì)算結(jié)果與試驗(yàn)結(jié)果吻合較好。在此基礎(chǔ)上，分析了影響型鋼高性能混凝土剪力墻變形能力的主要因素，包括軸壓比、配鋼率、高寬比和配箍特征值。通過建立的有限元模型，分析了不同軸壓比條件下約束邊緣構(gòu)件長(zhǎng)度與配箍特征值的設(shè)置要求。

Abstract:Based on the experiment of steel high performance  concrete (SHPC)  walls, nonlinear finite element analysis was performed to simulate the complete process of the loading and concrete crack of SHPC walls by ABAQUS. The nonlinear characteristic of material was taken into account in the models. The reliability of the finite element model was verified through the comparison of analysis results and experimental results. Based on the proposed model, parametric analysis was carried out to study the effect of axial load ratio, height-width ratio, stirrup characteristic value, and steel ratio on the seismic behavior of SHPC walls. The stirrup cha
