摘要
为研究抗扭钢-混凝土组合梁的构造要求和设计过程,分析了影响组合梁抗扭强度的主要因素,结合试验和理论分析成果,对抗扭组合梁的截面尺寸、纵筋和箍筋的最大、最小配筋率和间距的构造要求作了说明。给出了抗扭混凝土翼板截面的限制条件,提出了供实际使用的抗扭组合梁的实际设计方法。
In order to investigate the construction requirement and design program of composite steel-concrete beam under torsion,the main affecting factors are analyzed in detail. Based on the theoretical analysis and experimental results, the construction requirements such as section dimension, the maximal and minimal percentage of reinforcement of longitudinal bar and transverse bar, bar spacing, are explained. Restrict conditions of the beam section under torsion are given. The practical design program of composite beams to resist torsion combined with flexure and shear is presented for tentative recommendations.
