초록

The objective of this study is to propose the new punching shear model for two-way concrete slabs of building structures and bridge decks structures reinforced with FRP or steel rebars. To do this, two evaluating methods are applied here. One is the ratio of test to model and the other is probability analysis with probabilistic uncertainties. In conclusion, it shows that the proposed punching shear model evaluates the tested punching shear strength as conservative with stability and it exhibits better probabilistic characteristics than existing punching shear models.
