中文摘要：

为了研究GFRP/钢绞线复合筋混凝土梁的开裂性能,设计了5根GFRP/钢绞线复合筋混凝土梁试件,并对混凝土梁试件进行三分点静载试验研究,试验变量为混凝土梁截面尺寸和混凝土保护层厚度.在系统分析试验数据的基础上,提出GFRP/钢绞线复合筋混凝土梁抗裂承载力与最大裂缝宽度的计算方法,并给出使用荷载作用下的裂缝宽度限值.

英文摘要：

To study the cracking behavior of concrete beams reinforced with GFRP/steel wire composite rebar, five simply-supported beams were tested under three-point static load. The test variables were beam section size and concrete cover depth. Based on analysis on the test results, the calculation methods of cracking capacity and maximum crack width were proposed, and the limit value of crack width was suggested.
