摘要

钢筋混凝土平板或平板仍然是最受欢迎的地板系统之一，因为它能够被快速地施工，并且在与隔板相关的
位置具有灵活性。然而，缺乏双向剪切强度的平板 /平板楼板系统容易在板柱连接处发生脆性破坏，这种破坏可能会
蔓延并导致结构系统的较大部分逐渐倒塌。双向剪切强度不足可能是由于设计 /施工错误、材料强度不足或过载造成
的。片材和 /或带材形式的纤维增强聚合物（FRP）复合层压板用于结构缺陷的平板系统，以提高双向剪切能力、抗
弯强度、刚度和延展性。玻璃 FRP（GFRP）已成功地被使用，但碳 FRP（CFRP）板 /条 /层压板更常用作其他昂贵
和 /或具有挑战性的方法（如柱扩大）的实用替代品。本文回顾了有关在柱 /板交叉处利用 FRP板 /带和层压板以提
高平板的冲切强度的方法和有效性的文献。
