不同影响因素对型钢混凝土压弯扭构件抗扭承载力的影响

Effect of different influence factors on the torsional capacity of steel reinforced concrete bending torsion members

目前,国内外对于型钢混凝土的研究与实际工程建设相比仍然处于相对滞后的状态,其中存在许多关键性的科技问题亟需解决,比如压弯扭作用下闭合型钢混凝土构件承载力的计算研究。采用了ABAQUS有限元分析软件对闭合型钢混凝土压弯扭构件的受扭性能进行了分析研究,以传统强度叠加原理为基础,对闭合型钢混凝土构件在压弯扭作用下分析约束范围、纵筋、含钢率、型钢形状等影响因素对构件抗扭承载力的影响。

For now, at home and abroad the study of steel reinforced concrete is still in a state of relative lag compared with engineering construction, and there are many key scientific and technological problems are desiderate to be solved, such as computing research of the bearing capacity of closed steel reinforced concrete structures under bending torsion action. ABAQUS finite element analysis software was adopted to analyze the torsion performance of the bending torsion members, the influence of constraint, shape of longitudinal reinforcement, steel ratio, steel and other influence factors on torsional component bearing capacity was analyzed under bending torsional action based on the traditional strength superposition principle.
