In order to obtain a more accurate calculation model of punching shear capacity of FRP reinforced two-way concrete slab, taking the FRP reinforced two-way concrete slab as the research object, using the research methods of literature review, data statistics, model analysis and regression calculation, and with the help of the commonly used calculation model of punching shear capacity of FRP reinforced two-way concrete slab, based on the collected punching test data of 98 FRP reinforced two-way concrete slabs, the inversion method of critical punching section coefficient of two-way slabs was used to establish a new calculation model of punching bearing capacity of FRP reinforced two-way concrete slabs. The model has high accuracy in predicting the punching bearing capacity of FRP reinforced concrete structures under concentrated load. The predicted results are in good agreement with the experimental database. The model has guiding significance for the design of punching shear capacity of FRP reinforced two-way concrete slab, which provides an important reference for further improving the accuracy of punching shear capacity calculation model of FRP reinforced two-way concrete slab in the future.

为了得到较准确的FRP筋混凝土双向板冲切承载力的计算模型,以FRP筋混凝土双向板为研究对象,运用文献综述、数据统计、模型分析和回归计算等研究方法,借助常用的FRP筋混凝土双向板冲切承载力计算模型,对98块FRP筋混凝土双向板冲切试验数据进行计算和评估,并运用双向板临界冲切截面系数反演的方法,提出了一种新的FRP筋混凝土双向板冲切承载力的计算模型,该模型对FRP筋混凝土结构在集中荷载作用下冲切承载力的预测具有较高的精度,计算结果与试验数据库吻合较好。该研究对FRP筋混凝土双向板冲切承载力的设计具有指导意义,并对今后进一步提高FRP筋混凝土双向板冲切承载力计算模型的精度提供了重要参考。

为了得到较准确的FRP筋混凝土双向板冲切承载力的计算模型,以FRP筋混凝土双向板为研究对象,运用文献综述、数据统计、模型分析和回归计算等研究方法,借助常用的FRP筋混凝土双向板冲切承载力计算模型,对98块FRP筋混凝土双向板冲切试验数据进行计算和评估,并运用双向板临界冲切截面系数反演的方法,提出了一种新的FRP筋混凝土双向板冲切承载力的计算模型,该模型对FRP筋混凝土结构在集中荷载作用下冲切承载力的预测具有较高的精度,计算结果与试验数据库吻合较好。该研究对FRP筋混凝土双向板冲切承载力的设计具有指导意义,并对今后进一步提高FRP筋混凝土双向板冲切承载力计算模型的精度提供了重要参考。

In order to obtain a more accurate calculation model of punching shear capacity of FRP reinforced two-way concrete slab, taking the FRP reinforced two-way concrete slab as the research object, using the research methods of literature review, data statistics, model analysis and regression calculation, and with the help of the commonly used calculation model of punching shear capacity of FRP reinforced two-way concrete slab, based on the collected punching test data of 98 FRP reinforced two-way concrete slabs, the inversion method of critical punching section coefficient of two-way slabs was used to establish a new calculation model of punching bearing capacity of FRP reinforced two-way concrete slabs. The model has high accuracy in predicting the punching bearing capacity of FRP reinforced concrete structures under concentrated load. The predicted results are in good agreement with the experimental database. The model has guiding significance for the design of punching shear capacity of FRP reinforced two-way concrete slab, which provides an important reference for further improving the accuracy of punching shear capacity calculation model of FRP reinforced two-way concrete slab in the future.
