摘要
推导了含有配筋率的用于钢筋混凝土矩形梁正截面抗弯承载力、挠度及最大裂缝宽度计算的表达式。在满足正截面承载力要求的基础上,分析了纵向配筋率的变化对挠度及最大裂缝宽度的影响。
Calculated expressions including reinforcement ratio are deduced, which are applied to calculate flexural strength, deflection and maximum value of crack width of RC beam with rectangular section. Based on meeting the requirements offlexural strength, the effects made by ratio of longitudinal reinforcement on deflection and maximum value of crack width are analyzed.
