In Vietnam, there are currently no standards applicable to bridge structures in general and bridge decks in particular using GFRP bars. This paper presents the analysis and evaluation results of punching shear resistance prediction models of GFRP reinforced concrete bridge deck, based on the data of 34 deck slabs from previous studies and 09 deck slabs experimented by the author. In addition, using the nonlinear regression analysis method, an adjusted model has been proposed for the prediction results that are consistent with the experimental results.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"color: #000000;\"><b>Keywords: <\/b><em>GFRP bar; bridge deck; flexural behaviors; punching shear resistance.<\/em><\/span><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"Thanh polyme c\u1ed1t s\u1ee3i th\u1ee7y tinh (GFRP) \u0111\u00e3 \u0111\u01b0\u1ee3c s\u1eed d\u1ee5ng thay th\u1ebf c\u1ed1t th\u00e9p trong k\u1ebft c\u1ea5u b\u1ea3n m\u1eb7t c\u1ea7u \u1edf nhi\u1ec1u qu\u1ed1c gia nh\u1eb1m m\u1ee5c \u0111\u00edch n\u00e2ng cao \u0111\u1ed9 b\u1ec1n cho c\u00f4ng tr\u00ecnh.
