摘要
本文首先讨论了普通混凝土梁中和轴高度和塑性系数的计算问题,在此基础上根据对钢纤维混凝土梁弯曲性能的分析,提出了与普通混凝土相衔接的钢纤维混凝土梁中和轴高度、初裂弯矩以及极限弯矩的计算公式.
In this paper,the calculating problems akout neutral axis height and plastic factor of plain concrete are first diocuued. Based on this ,the calculating fermulao of nrutral axio height,initial cracking memker and ulti mate member of SFCbeam are put forward,which is connected with plain ckncrete beam.
