地基与钢筋混凝土界面特性:对砂土与混凝土界面进行了平面剪切试验,成功地建立了考虑摩擦力和粘结力的界面单元。对地下结构动力响应的边界特性进行了敏感性分析。三维钢筋混凝土本构模型采用路径相关本构模型对多向裂纹进行数值处理,分别采用三维Mindlin板有限元和实体RC格式。箱型壳在三维循环荷载作用下:偏心力作用产生面内和平面外的耦合作用。利用试验数据对编制的非线性有限元程序进行了验证。针对地下城市道路隧道穿越软土地基、钢筋混凝土套筒地基和钢筋混凝土框架地铁车站的抗震性能进行了分析,并进行了非线性动力分析。这些结果有助于起草JSCE关于抗震性能评估检查的建议。
英文摘要
Boundary characteristics of foundation and reinforced concrete : Plane shear test for interface between sandy soil and concrete was conducted and a boundary interface element to take into account friction and cohesive bond was successfully developed. Asensitivity analysis was carried out for boundary properties to dynamic response of underground structures.3D-RC constitutive law : Multi-directional cracks were numerically handled by the path-dependent constitutive model and implemented into layr 3D Mindlin plate finite element and solid RC scheme.Box-type shell under 3D cyclic actions : Eccentric force which creates coupled in-plane and out-of-plane actions was applied to the 3D space box frames. With this experimental data, the nonlinear FEM program developed was examined and verified.Seismic performance evaluation : Uunderground urban road tunnel passing through soft foundation, RC casing foundation and RC framed subway station were targeted, and developed nonlinear dynamic analysis was applied. These results served to draft the JSCE proposal on seismic performance evaluation check.
