摘要:
基于结构精细化模拟分析平台RSAPS, 开发了柔度法纤维梁柱单元模型, 并将混凝土单轴损伤本构模型开发到RSAPS材料库中, 同时通过引入截面单元模型, 结合钢筋应力-滑移关系模型并考虑钢筋黏结滑移效应, 建立了钢筋混凝土墩柱构件的损伤分析方法.应用RSAPS平台分别对钢筋混凝土柱的拟静力试验和桥墩的振动台试验进行模拟分析.结果表明, RSAPS平台可有效模拟钢筋混凝土构件损伤演化过程, 描述构件的薄弱部位, 且具有较高计算效率, 从而为桥梁结构地震灾变过程模拟提供了实用的分析手段.
Abstract:
Based on the RSAPS simulation platform,the flexibility-based fiber beam-column element model was developed with a uniaxial damage concrete constitutive model introduced into RSAPS/MAT. Meanwhile,a section element combined with a steel stress-slip model was developed and implemented in RSAPS to simulate the bond-slip effects. Thus,a damage analysis method for reinforced concrete(RC)members was established. A pseudo-static test on a RC column and a pier shaking table test were simulated using the platform RSAPS. The results indicate that the damage evolution process and the weak parts of RC members can be simulated effectively with high computational efficiency by platform RSAPS,which provides a practical analysis tool to simulate the disaster evolution process of bridges.
