对超高性能混凝土UHPC(Ultra-High Performance Concrete)剪力墙在单向水平荷载作用下的受力过程进行了非线性有限元分析。重点分析了轴压比、剪跨比、暗柱纵筋配筋率、暗柱箍筋配箍率、分布钢筋配筋率等因素对UHPC剪力墙抗剪承载力的影响。结果表明： UHPC混凝土剪力墙抗剪承载力高，延性较好，值得在工程领域应用。随着轴压比的增大，承载力先增大后减小，延性大幅下降，应该严格控制轴压比；随着剪跨比增大，破坏形态发生变化，承载力减小；随着暗柱纵筋配筋率的增大，承载力增大；暗柱箍筋体积配箍率及分布钢筋的增大对承载力的影响不很明显。
對超高性能混凝土UHPC(Ultra-High Performance Concrete)剪力牆在單嚮水平荷載作用下的受力過程進行瞭非線性有限元分析。重點分析瞭軸壓比、剪跨比、暗柱縱觔配觔率、暗柱箍觔配箍率、分佈鋼觔配觔率等因素對UHPC剪力牆抗剪承載力的影響。結果錶明： UHPC混凝土剪力牆抗剪承載力高，延性較好，值得在工程領域應用。隨著軸壓比的增大，承載力先增大後減小，延性大幅下降，應該嚴格控製軸壓比；隨著剪跨比增大，破壞形態髮生變化，承載力減小；隨著暗柱縱觔配觔率的增大，承載力增大；暗柱箍觔體積配箍率及分佈鋼觔的增大對承載力的影響不很明顯。

This paper uses nonlinear finite element analysis upon the basic behavior of Ultra -high performance concrete shear wall subjected to monodirectional lateral load, and studies the effect of axial load ratio, shear span ratio, the ratio of hidden column longitudinal, the volumetric ratio of hidden column and the ratio of web reinforcement on the shear bearing capacity. The research shows that: the bearing capacity of UHPC shear wall is high; the displacement ductility of UHPC shear wall is well. With the increased of axial load ratio, the bearing capacity is first increased and then decreased, the ductility drop significantly, so axial load ratio should be strictly controlled; With the shear span ratio increased, the destruction of morphological change and the bearing capacity increase; With the ratio of hidden column longitudinal increasing, the bearing capacity increase; the volumetric ratio of hidden column, the ratio of web horizontal reinforcement and the ratio of web vertical reinforcement effect on bearing capacity are not very obvious.
