聚合物纤维网面层加固砌体的粘结本构模型

Bond-Slip Model of Masonry Reinforced by Polymer Fiber Mesh

基于Yuan和Teng的双线性粘结滑移模型,考虑了纤维材料在剥离阶段与基体间的摩擦和机械咬合作用,提出了三线性粘结滑移本构模型,推导了拉拔过程中的纤维粘结应力以及荷载、滑移表达式,与试验结果吻合良好.

In order to study the bond slip relationship in the material drawing process,a trilinear bond-slip constitutive model proposed based on Yuan an d Teng’s bilinear bond-slip model in consideration of the friction and mechanical occlusion between the fiber material and the matrix during the stripping stage,and the expressions of the bond stress,load,and slip of the fiber during the drawing process are derived,which are in good agreements with the test results.
