摘要:
随着碳纤维布在木结构古建筑加固领域的广泛应用,明确碳纤维布与木材之间的界面粘结力学性能是进行加固的前提和基础.主要结合碳纤维布-木材的单剪试验,对5个粘贴碳纤维布的试验木块采用AN-SYS有限元软件进行了非线性数值模拟,研究了碳纤维布粘结长度及宽度变化对极限粘结荷载的影响,分析了碳纤维布的应变分布规律以及界面粘结剪应力的分布特点和传递过程,并给出了试验值和计算值的误差分析.计算结果表明,采用的模拟界面粘结性能的有限元方法具有可行性
Abstract:
With the CFRP widely used in the field of strengthened ancient structure, explicit bonding property between the CFRP and wood was the premise and foundation of strengthening. Based on the single-shear experiment between CFRP and wood, nonlinear numerical analysis was carried out on 5wood sticking CFRP by ANSYS finite element software, and the influence of the limit bonding load produced due to the change of CFRP bond length and width. The strain distribution rule of CFRP and distribution characteristics of bonding shear stress in interface and transfer process were obtained, and the error analysis between test value and calculated value was given. The calculated results showed that it was feasible to simulate the bonding property in interface by finite element method
