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。
At present, the research on SRC at home and abroad is still relatively lagging behind the actual engineering construction. There are many key technical problems to be solved, such as the calculation research on the bearing capacity of SRC under compression and bending. The ABAQUS finite element analysis software was used to analyze the torsional behavior of the closed steel-concrete compression-bending torsion members. Based on the traditional superposition principle, the confined scope of the closed-type steel-concrete members under compression bending and torsion was analyzed. Influence of factors such as steel content and shape of steel on torsional bearing capacity of members.
