| 摘 要： | 提出了一种新型的FRP-混凝土复合桥面板.新型桥面板下部由3个GFRP箱型构件共同组成,并构成桥面板的受拉层,上部浇筑混凝土作为桥面板的受压层,这种形式的截面设计可以充分发挥两种不同材料各自的优势,并可大大增加GFRP材料构件的刚度.采用有限元技术研究了新型桥面板在荷载作用下的受弯性能,结果表明有限元分析是进行新型桥面板在荷载作用下弯曲性能研究的有效途径.

| Abstract: | A new concept for a hybrid FRP-concrete bridge deck systems was presented.Three rectangular GFRP box sections were bonded together to form the tensile layer.And a layer of concrete was placed in the compression zone of those sections.The new designed method was proposed to make the best of each constituent material and increase the stiffness of GFRP composite structures.The static flexural behavior of the bridge deck under loads was predicted on the finite element analysis.The results from the FEA showed that a linear FEA could accurately predict the static behavior of this new bridge deck under design live loads. |
