Study on mixed mode fracture properties of high-strength fiber-reinforced concrete used as earthquake resisting materials

研究了纤维砂浆和瓷砖饰面混凝土的混合模态断裂行为，验证了这些饰面材料作为隔震装置的有效性。提出了评价混凝土及其饰面材料三维裂纹扩展的数值分析方法，分析结果与试验结果具有较好的相关性。获得了整理层抗震加固性能的评价数据。

Mixed mode fracture behavior of a concrete with fiber reinforced mortar and porcelain tile finishing was investigated and the effectiveness for those finishing materials as a seismic isolation device was cleared. Numerical analysis method to evaluate the 3D crack propagation of a concrete and finishing materials was proposed and a good correlation was found between the analysis results and the test results. Evaluation data on the seismic retrofit performance of finishing was obtained.
