Hollow interlayer steel pipe concrete combined member based on multi-mechanism energy absorption
The invention relates to the technical field of buildings and bridges, and provides a multi-mechanism energy absorption-based hollow sandwich steel tube concrete combined member which comprises a steel structure tubular inner layer, a steel structure tubular outer layer, a self-repairing concrete column layer, a honeycomb structure layer and a buffer structure layer, and the cross section of the steel structure tubular outer layer is of a concave-convex structure; the steel structure tubular outer layer is arranged on the peripheral side of the steel structure tubular inner layer in a sleeving mode, and an annular cavity is formed between the steel structure tubular outer layer and the steel structure tubular inner layer in a spaced mode. The annular cavity is filled with the self-repairing concrete column body layer; the honeycomb structure layer is arranged between the self-repairing concrete column body layer and the steel structure tubular outer layer; the buffering structure layer is arranged between the honeycomb structure layer and the steel structure tubular outer layer, and the buffering structure layer and the steel structure tubular outer layer are arranged in an embedded mode. The bearing capacity and flexural rigidity of the hollow interlayer steel pipe concrete member are improved, and the maintenance cost and the damage and fracture risks are reduced.
本发明涉及建筑与桥梁技术领域，提供一种基于多机制吸能的中空夹层钢管混凝土组合构件，其包括钢结构管状内层、钢结构管状外层、自修复混凝土柱体层、蜂窝结构层和缓冲结构层，钢结构管状外层的横截面呈凹凸结构设置，钢结构管状外层外套于钢结构管状内层的外周侧，且钢结构管状外层与钢结构管状内层之间间隔形成环形空腔；自修复混凝土柱体层填设于环形空腔内；蜂窝结构层设于自修复混凝土柱体层与钢结构管状外层之间；缓冲结构层设于蜂窝结构层和钢结构管状外层之间，缓冲结构层与钢结构管状外层相互嵌合设置。本申请实现了提高中空夹层钢管混凝土构件的承载力与抗弯刚度，并减少维护成本、损坏和断裂的风险。
