| 摘 要： | 对于砌体墙,尤其是老旧建筑和有保护价值建筑的砌体墙,碳纤维加固有着重要意义。基于试验研究提出了碳纤维布加固有洞口和无洞口砖墙,碳纤维布加固有洞口砼小型空心砌块砌体墙抗剪承载力计算公式。公式中引入了碳纤维对砌体墙抗剪强度修正系数ηcf。该系数的引入使该文计算公式与现行《砌体结构设计规范》中未加固砌体墙斜截面受剪承载力计算公式有着相近的可靠度。

| Abstract: | CFRP(Carbon Fiber Reinforced Polymer) strengthened masonry walls are of great importance,especially for old and historical buildings.Based on the experiments,shear strength calculation formulas for CFRP strengthened brick walls with and without holes,and CFRP strengthened walls of concrete hollow blocks with holes are suggested,to which the factor of CFRP restriction to walls is introduced.The factor gives the formulas similar reliabilities to those of non-strengthened walls in Code for Design of Masonry Structures. |
