RESPONSE AND SENSITIVITY ANALYSIS OF CONTINUOUS BEAM MODEL USING ENGINEERED CEMENTITIOUS COMPOSITE (ECC) UNDER SEISMIC LOADING

  • 摘要: 综述了高延性纤维增强水泥基复合材料(engineered cementitious composite,ECC材料)在拉伸荷载下呈现高延展性等特点,常用于弥补普通混凝土抗拉性能不足的缺点。该文基于现有的ECC本构模型,利用非线性有限元平台OpenSees对已有的算法进行二次开发,利用OpenSees建立ECC连续梁模型,并将模拟结果与试验结果进行了比较分析。该文基于直接微分法(direct differentiation method,DDM),推导实现ECC材料参数的敏感性算法,并将DDM计算结果与有限差分法(finite difference method,FDM)结果进行对比,验证了DDM分析算法的优越性。该文利用连续梁算例,体现敏感性分析的重要性,并将模拟结果进行分析总结。
