Concrete filled steel tube-steel tube vertical mixed structure system
The invention discloses a concrete filled steel tube-steel tube vertical mixed structure system, and relates to the field of building structures, in particular to the field of steel structures and steel-concrete composite structures. The structure system comprises a lower floor steel pipe concrete column, an upper floor steel pipe column, a steel pipe concrete-steel pipe conversion column and a steel pipe concrete-steel pipe transition section corner shear connector. The structural system comprises a middle transition method and a whole-layer transition method, and interlayer concrete filled steel tube-steel tube conversion columns exist in the middle transition method. When the device is applied to a building structure, the bearing capacity of the steel frame can be effectively improved, arrangement of supports or shear walls is reduced, and a system is optimized; the lower part is filled with concrete, so that the rigidity, the strength, the deformability and the impact resistance of the column are enhanced, the section sizes of the lower floor steel pipe concrete column and the upper floor steel pipe column are kept consistent, the structural requirement is met without increasing the section of the steel pipe, the section transition procedure is reduced, and the construction cost is reduced. The construction cost is reduced, the engineering construction progress is accelerated, the use area of a building is increased, and the economic value of the building is improved; the anti-explosion, anti-impact and anti-flood capacities of the structure are improved through the concrete filled steel tubular column on the lower portion. The method can be used for optimization design of newly-built steel structures, reinforcement and reconstruction of old steel structure houses and structural post-earthquake repair.
本发明公开了一种钢管混凝土‑钢管竖向混合结构体系，涉及建筑结构领域，尤其涉及钢结构与钢‑混凝土组合结构领域。该结构体系包含下部楼层钢管混凝土柱、上部楼层钢管柱、钢管混凝土‑钢管转换柱及钢管混凝土‑钢管过渡段角部抗剪连接件。该结构体系包含中间过渡法与整层过渡法，中间过渡法存在层间钢管混凝土‑钢管转换柱。将本发明应用到建筑结构中，将有效提升钢框架承载力，减少支撑或者剪力墙的设置，优化体系；可用于下部层高大于上部层高的建筑中，下部内填充混凝土增强了柱的刚度、强度、变形能力与抗冲击能力，使得下部楼层钢管混凝土柱与上部楼层钢管柱的截面尺寸保持一致，不必增大钢管截面便实现结构需求，减少了截面过渡的工序，降低了施工成本，加快了工程施工进度，增加了建筑使用面积，提高了建筑的经济价值；下部钢管混凝土柱增大结构抗爆、抗冲击及抗洪能力。本发明可用于新建钢结构优化设计与老旧钢结构房屋加固改造及结构震后修复之中。
