Description
技术领域technical field
本发明属于建筑结构技术领域,具体涉及一种高强螺旋钢纤维混凝土柱和蜂窝钢梁RCS组合件及其施工方法。The invention belongs to the technical field of building structures, and in particular relates to a high-strength helical steel fiber reinforced concrete column and a honeycomb steel beam RCS assembly and a construction method thereof.
背景技术Background technique
RCS组合结构是一种新型的结构形式，它是由钢筋混土柱和钢梁组成的框架结构。RCS组合结构体系同时具备了传统的钢结构和RC结构两种体系的优点。 RC柱的侧向刚度和强度要优于钢柱；而且RC柱要比钢柱更加经济。钢梁施工速度快于混凝土梁。RCS混合框架结构与普通钢筋混凝土结构相比，具有更轻的自重，更大的建筑可用空间，更快的施工速度等优点；而与钢结构相比，则有着更低的造价，并且在刚度、耐火性以及耐用性等方面都有更优异的表现。基于上述优点，RCS组合结构已经获得了世界各国工程人士的重视。由于混凝土是脆性材料，当其变形超过其极限压应变时，混凝土将会被压溃，承载力下降。而RCS节点区域主要破坏形式之一为混凝土承压破坏。RCS composite structure is a new type of structure, which is a frame structure composed of reinforced concrete columns and steel beams. The RCS composite structure system has the advantages of the traditional steel structure and the RC structure at the same time. The lateral stiffness and strength of RC columns are better than steel columns; and RC columns are more economical than steel columns. Steel beams are constructed faster than concrete beams. Compared with ordinary reinforced concrete structure, RCS hybrid frame structure has the advantages of lighter self-weight, larger available building space and faster construction speed; , fire resistance and durability have better performance. Based on the above advantages, the RCS composite structure has won the attention of engineers from all over the world. Since concrete is a brittle material, when its deformation exceeds its ultimate compressive strain, the concrete will be crushed and the bearing capacity will decrease. One of the main failure forms in the RCS node area is concrete compression failure.

本发明相对于现有技术具有以下优点及突出效果：Compared with the prior art, the present invention has the following advantages and outstanding effects:
本发明提出螺旋钢纤维混凝土柱和蜂窝钢梁RCS组合件，用以改善混凝土极限压应变，进而提高环式焊接箍筋高强混凝土柱和蜂窝钢梁RCS组合件延性，增强RCS节点区域承压能力。钢纤维在混凝土中乱向分布，阻碍混凝土内部微裂缝的扩展和阻滞宏观裂缝的发生和发展，进一步提高了组合柱的延性。另外，由于该组合柱延性得到了改善，提高了其地震发生时耗能能力，从而增强了环式焊接箍筋高强螺旋钢纤维混凝土柱和蜂窝钢梁RCS组合件的抗震性能。环式焊接箍筋具有以下优点：(1)环式焊接箍筋对混凝土提供的约束力远大于普通弯钩箍筋；(2)梁柱节点处普通弯钩箍筋调位困难，容易造成少放，不放节点箍筋的情况，大大降低了框架节点的抗震能力，而环式焊接箍筋则不存在这些情况。(3)采用环式焊接箍筋，混凝土浇筑时下料较容易，不容易造成孔洞或露筋等情况。综上所述，环式焊接箍筋高强螺旋钢纤维混凝土柱和蜂窝钢梁RCS 组合件将大大促进了RCS组合结构的发展以及工程实际应用。The invention proposes a spiral steel fiber concrete column and a honeycomb steel beam RCS assembly, which is used to improve the ultimate compressive strain of concrete, thereby improving the ductility of the ring welded stirrup high-strength concrete column and the honeycomb steel beam RCS assembly, and enhancing the pressure bearing capacity of the RCS node area. . The random distribution of steel fibers in the concrete hinders the expansion of micro-cracks in the concrete and the occurrence and development of macro-cracks, which further improves the ductility of the composite column. In addition, due to the improved ductility of the composite column, its energy dissipation capacity during earthquakes is improved, thereby enhancing the seismic performance of the ring welded stirrup high-strength helical steel fiber reinforced concrete column and honeycomb steel beam RCS composite. Ring-type welded stirrups have the following advantages: (1) The binding force provided by ring-type welded stirrups to concrete is much greater than that of ordinary hook stirrups; (2) It is difficult to adjust the position of ordinary hook stirrups at beam-column joints, which is easy to cause less The situation of placing or not placing the joint stirrups greatly reduces the seismic capacity of the frame joints, while the ring welded stirrups do not exist in these situations. (3) Ring-type welded stirrups are used, and it is easier to cut materials during concrete pouring, and it is not easy to cause holes or exposed ribs. To sum up, the RCS assembly of high-strength helical steel fiber reinforced concrete columns and honeycomb steel beams with ring welded stirrups will greatly promote the development and practical application of RCS composite structures.
