玻璃钢筋增强树脂混凝土梁的弯曲性能研究

The Flexural Properties of GFRP Polymer Concrete Beam

对玻璃钢筋增强树脂混凝土 (GFRP)梁进行弯曲性能试验研究 ,并在现有的玻璃钢筋增强水泥混凝土梁分析模型的基础上 ,提出了用于玻璃钢筋增强树脂混凝土梁挠度计算的修正模型。利用该修正模型对梁内部出现微裂纹后的挠曲性能进行评估 ,其结果与实测结果吻合较好。

This paper presented some experiments and theoretical analysis about the flexural capability of the GFRP polymer concrete beam. Based on the used analysis model about GFRP concrete beam, it put forward a modified model used to calculate the flexibility of the GFRP polymer concrete which is obtained by combining the characteristics of the GFRP polymer concrete beam with the results of flexural experiments. This modified model is used to evaluate the flexural capability of some beams after the first crack appeared. It is found that the results from the model and the experiments matched well.
