为保证大截面矩形钢管混凝土柱的钢管与核心混凝土协同工作，配置梁安装在钢管混凝土柱楼板节点区域。配筋梁作为传力构件，使外荷载由钢管和核心混凝土共同承担，钢管和核心混凝土的变形基本满足平面截面假设。配筋梁的设计可采用本文提出的有限元法和弹性基础梁法。最后，对单配梁的解析解与数值解进行了对比分析，进一步验证了理论的合理性。
To ensure that the steel tube and core concrete work together for large section rectangular concrete filled tube columns, the allocated beams are installed where the node area of concrete filled tube columns floor. As force transmission components, allocated beams make the external load beared by the steel tube and core concrete together, and the deformation of the steel tube and core concrete basically meets the plane section assumption. The design of allocated beam can apply the finite element method and elastic foundation beam method advanced by this paper. Finally, the comparative analysis between analytical and numerical solutions of single allocated beam, verifys further the rationality of theory.
