| 中文摘要 | 由于受到试验设备加载能力等研究条件的限制,目前FRP加固钢筋混凝土柱的破坏机理研究主要都是基于小尺寸试件的破坏试验,其研究成果对现代大型土木工程常用的大尺寸构件是否适用还没有得到验证。在修正尺寸效应律公式的基础上,对FRP约束圆形混凝土柱的极限强度公式进行调整,推导了反映尺寸效应的FRP约束矩形截面混凝土柱的极限强度计算公式,计算结果与试验结构吻合较好。; Due to research limitations,such as the loading capacity of test equipment,the failure mechanism of FRP strengthened concrete structure design is mainly based on small size destructive test,whether it is scientific and rational to be used for large-size component in modern large-scale civil engineering haven't been verified. Based on the idea of modified size effect law and the model of circular concrete columns,new models for predicting strength of rectangular columns confined with FRP are proposed,which can reflect the effect of different columns sizes on the compressive strength. The comparison with experiment results and existing models shows that the proposed models are more accurate. |
