Outline
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.
