项目摘要

This research focuses on the mechanics of fiber reinforced cementitiou composites especially under multi-directional cracking condition. To clarify the performance, experimental investigation was firstly conducted and the degradation of strength and stiffness were confirmed that were depending on the initial cracking angle and damage level. Based on the experimental result and the previous researches, the constitutive model was developed and verified by FEM. Furthermore, analysis was expanded to structural level especially in shear critical member. Through the results, applicability of the developed model were verified.
这项研究的重点是纤维增强胶质材料复合材料的力学,尤其是在多方向开裂条件下。为了阐明性能,首先进行了实验研究,并确认强度和刚度的降解取决于初始裂纹角度和损伤水平。基于实验结果和先前的研究,由FEM开发和验证了本构模型。此外,分析扩展到结构水平,尤其是在剪切关键成员中。通过结果,验证了开发模型的适用性。
