| 摘 要： | 基于修正斜压场理论和扰动应力场模型分别对不同剪跨比的高强混凝土剪力墙拟静力试验进行数值模拟，得到相应的滞回曲线和骨架曲线。与试验数据对比，结果表明：较之于修正斜压场理论模型，基于扰动应力场模型计算的PΔ滞回曲线与试验PΔ滞回曲线吻合更好，得到的破坏形态及裂缝分布图与试验基本相同。充分说明了基于扰动应力场模型的有限元数值模型能够较好地模拟循环荷载作用下的高强混凝土剪力墙构件的滞回特性。

| Abstract: | The simulations of the nonlinear response of quasi-static tests of HSC shear wall specimens with different shear span ratios under reversed cyclic type loading was carried out. The finite element model based on Modified Compression Field Theory (MCFT) and Disturbed Stress Field Model (DSFM), respectively, is used for HSC shear wall specimens. The hysteretic curves and skeleton curves are compared with the experimental results. The results shows that the simulative hysteretic curves, failure modes and cracking patterns of the finite element models, based on DSFM, is more consistent with the experiment results compared with MCFT. This fully shows that the finite element models, based on DSFM, could simulate the hysteretic Characteristics of HSC shear wall specimens well. |
