Description
技术领域technical field
本发明涉及一种带十字形约束缀板箱形钢骨约束混凝土柱及作法，主要应用于建筑结构中的抗震耗能领域。The invention relates to a box-shaped steel-reinforced concrete column with cross-shaped restraint panels and a method thereof, which are mainly used in the field of anti-seismic energy consumption in building structures.
背景技术Background technique
钢骨混凝土结构指在普通钢筋混凝土结构中配置钢骨的组合结构体系。在钢骨混凝土结构中，钢骨可分为实腹式和空腹式两种。实腹式钢骨混凝土构件具有较好的抗震性能，而空腹式钢骨混凝土构件的抗震性能与普通钢筋混凝土构件基本相同。因此，目前在抗震结构中多采用实腹式钢骨混凝土构件。实腹式钢骨可由钢板焊接拼制而成或直接采用轧制型钢。Steel-reinforced concrete structure refers to a composite structure system in which steel reinforcement is arranged in an ordinary reinforced concrete structure. In the steel reinforced concrete structure, the steel frame can be divided into two types: solid belly type and hollow type. The solid-web steel-reinforced concrete members have better seismic performance, while the seismic performance of the empty-web steel-reinforced concrete members is basically the same as that of ordinary reinforced concrete members. Therefore, at present, solid-web steel-reinforced concrete members are mostly used in earthquake-resistant structures. The solid-belly steel frame can be assembled by welding steel plates or directly using rolled steel.
研究表明，在配置一定构造要求柔性钢筋的情况下，钢骨混凝土结构中钢和混凝土能协同工作，直至达到极限承载力；钢骨混凝土结构综合了钢结构和钢筋混凝土结构二者的优点。与钢结构相比，它具有比较大的刚度和阻尼，有利于控制结构的变形；外包混凝土可以起到防止钢骨腐蚀和提高结构耐火性能的作用；外包混凝土也可以防止钢骨局部屈曲，使钢骨强度得到充分利用，节约钢材。同钢筋混凝土结构相比，钢骨提高了结构的承载力和延性，有利于减小构件截面尺寸，有利于结构抗震；钢骨混凝土中钢骨在混凝土浇灌前己形成可独立承载的结构体系，可承受施工活荷载和结构自重，无需设置临时支撑，在多高层建筑中不必等待混凝土达到一定强度后再施工，可缩短建设工期。Studies have shown that under the condition that a certain structure requires flexible steel bars, steel and concrete in steel reinforced concrete structures can work together until the ultimate bearing capacity is reached; steel reinforced concrete structures combine the advantages of steel structures and reinforced concrete structures. Compared with the steel structure, it has relatively large rigidity and damping, which is beneficial to control the deformation of the structure; the outsourcing concrete can prevent the corrosion of the steel frame and improve the fire resistance of the structure; the outsourcing concrete can also prevent the local buckling of the steel frame, making the The strength of the steel frame is fully utilized, saving steel. Compared with the reinforced concrete structure, the steel frame improves the bearing capacity and ductility of the structure, which is conducive to reducing the cross-sectional size of the component and is conducive to the earthquake resistance of the structure; in the steel reinforced concrete, the steel frame has formed a structural system that can independently carry the load before the concrete is poured. It can bear the construction live load and the self-weight of the structure without setting up temporary supports. In multi-story buildings, it is not necessary to wait for the concrete to reach a certain strength before construction, which can shorten the construction period.
在结构设计中，有时因建筑设计需要，柱的截面尺寸受到限制，当采用钢骨混凝土柱时，往往通过提高截面配钢率以提高其承载力及延性。如内置箱形钢骨型钢混凝土柱，钢骨材料离中性轴较远，可提供较大的惯性矩，但当钢骨边长较长或钢板厚度较薄时，箱型钢骨钢板承受较大的径向压力时，易发生失稳，钢骨对混凝土的约束能力下降，继而整个型钢混凝土柱承载力下降。因此，当箱型截面钢骨边长较长或钢板厚度较薄时，应采用有效的措施约束其屈曲变形，以提高整个混凝土柱的承载力及延性。In structural design, sometimes due to architectural design requirements, the section size of the column is limited. When steel reinforced concrete columns are used, the bearing capacity and ductility are often improved by increasing the steel ratio of the section. For example, if the box-shaped steel frame steel concrete column is built in, the steel frame material is far away from the neutral axis, which can provide a large moment of inertia, but when the side length of the steel frame is long or the thickness of the steel plate is thin, the box-shaped steel frame steel plate bears a large When the radial pressure is high, it is prone to instability, the restraint ability of the steel frame to the concrete decreases, and then the bearing capacity of the entire steel concrete column decreases. Therefore, when the side length of the box-section steel frame is long or the thickness of the steel plate is thin, effective measures should be taken to restrain its buckling deformation, so as to improve the bearing capacity and ductility of the entire concrete column.
