前言根据中国建筑科学研究院下达第三批重点科研项目,广西大学土木系是承担钢筋混凝土T形截面和I字形截面受扭构件试验研究的单位之一。本阶段试验探讨T形截面构件的开裂扭矩、腹部配筋构件的极限承载能力和刚度。本文就所做的8根纯混凝土构件、15根只在腹部配筋而翼缘不配筋的构件和3根腹翼皆配筋的构件的试验结果,提出相应的计算式。
Foreword According to the third batch of key scientific research projects issued by China Academy of Building Research, the Department of Civil Engineering of Guangxi University is one of the units responsible for the torsion member test of reinforced concrete T-section and I-shaped section. This stage of the test to explore the T-section member cracking torque, the ultimate bearing capacity and stiffness of the abdominal reinforcement members. In this paper, the calculation results of the 8 pure concrete components, 15 components with only reinforcement in the abdomen and no reinforcement in the flange, and 3 components with reinforcement in the abdominal wing are proposed.
