| 摘 要： | 对12根高强钢筋作箍筋的T形截面钢筋混凝土简支梁进行了试验研究。分析了混凝土强度、配箍率和加载方式对斜裂缝宽度的影响,建立了计算配高强箍筋的混凝土梁的斜裂缝宽度的实用公式。研究结果表明,混凝土强度大于等于C40时,配高强箍筋的混凝土梁的斜裂缝宽度可以满足《混凝土结构设计规范》(GB50010-2002)正常使用极限状态验算中裂缝宽度限值的要求。

| Abstract: | Experimental research on 12 simply supported reinforced concrete T-beams with high-strength stirrup were performed.Analyzing the experimental data from concrete strength,stirrup ratio and loading form,a formula for calculating diagonal crack widths of the reinforced concrete T-beam with high-strength stirrup was established.From the obtained results it can be seen that if concrete strength is greater than or equal to C40,diagonal crack width of reinforced concrete T-beams with high-strength stirrup can satisfy the requirement of Code for Design of Concreter Structure(GB50010-2002). |
