摘要
本文通过三点弯曲试脸,探讨了钢纤维体积率对钢纤维混凝土弯曲性能的影响,运用阻裂理论推导正截面强度的计算模式.在综合分析试验结果的基础上,给出了与普通混凝土抗裂计算相衔接的钢纤维混凝土初裂抗弯强度和抗折强度的计算公式.
By three point bending tests,the paper has studied the affection of the fibre content by valume to the ending behavier of SFC.The fibre spacing theory has been used to derive thecalculating model of the positive ection trength.Based on the all analysis to the test results,the formula of the first cracking and repture strength connected ith plain concrete have beengiven.
