Description
技术领域technical field
本发明涉及一种震后自复位的偏心支撑钢框架的组合楼板，属于结构工程技术领域，适用于高层及超高层钢结构中。The invention relates to a combined floor slab of eccentrically supported steel frame that self-resets after an earthquake, belongs to the technical field of structural engineering, and is suitable for high-rise and super high-rise steel structures.
背景技术Background technique
偏心支撑钢框架结构是一种比较理想的结构抗侧力体系，具有刚度大、抗震性能好、受力性能合理等优点，性能优于纯框架结构和中心支撑框架结构。偏心支撑钢框架结构主要由消能梁段、非消能梁段、支撑和柱等构件组成，如图1所示。其中，在支撑与柱、支撑与梁或支撑与支撑之间形成的一段短梁称为消能梁段。在使用功能上，消能梁段可作为普通梁，为结构提供刚度并支撑楼板；多遇地震下，偏心支撑钢框架具有较高的抗侧移能力，能简单地满足结构的抗侧移要求，并具有良好的变形能力；罕遇地震下，消能梁段相当于结构的“保险丝”，在主体结构进入非弹性状态前率先进入屈服并耗能，即结构通过消能梁段的剪切屈服或弯曲屈服来耗散大量的地震能量，最大限度地减小主体结构在地震中的损伤，并保证支撑在整个过程中不发生屈曲。The eccentrically braced steel frame structure is an ideal structural lateral force resistance system, which has the advantages of high rigidity, good seismic performance, and reasonable mechanical performance, and its performance is superior to that of pure frame structures and centrally braced frame structures. The eccentrically braced steel frame structure is mainly composed of energy-dissipating beam sections, non-energy-dissipating beam sections, supports and columns, as shown in Figure 1. Among them, a short beam formed between a support and a column, a support and a beam, or a support and a support is called an energy-dissipating beam section. In terms of function, the energy-dissipating beam section can be used as an ordinary beam to provide rigidity for the structure and support the floor slab; under frequent earthquakes, the eccentrically supported steel frame has a high ability to resist lateral movement, which can simply meet the requirements of the structure for anti-lateral movement , and has good deformation capacity; under rare earthquakes, the energy-dissipating beam section is equivalent to the "fuse" of the structure. Yield or bending yield to dissipate a large amount of seismic energy, minimize the damage of the main structure in the earthquake, and ensure that the support does not buckle during the entire process.
当消能梁段发生非弹性变形时，可能会引起其上部及与非消能梁段连接处的混凝土楼板开裂，且传统的消能梁段与非消能梁段为一根整梁，当消能梁段发生损伤或破坏时，非消能梁段端部也可能发生屈服或破坏，对结构的使用功能及合理性造成一定影响，不利于震后及时有效的修复。另外，当消能梁段上也有现浇组合楼板，其承载能力较大，使结构很难保证构件的屈服仅出现在消能梁段上。When the energy-dissipating beam section undergoes inelastic deformation, it may cause cracks on the upper part and the concrete floor at the joint with the non-energy-dissipating beam section, and the traditional energy-dissipating beam section and the non-energy-dissipating beam section are a whole beam. When the energy-dissipated beam section is damaged or destroyed, the end of the non-energy-dissipated beam section may also yield or fail, which will have a certain impact on the use function and rationality of the structure, and is not conducive to timely and effective repair after the earthquake. In addition, when there is also a cast-in-situ composite floor on the energy-dissipating beam section, its bearing capacity is relatively large, which makes it difficult for the structure to ensure that the yield of components only occurs on the energy-dissipating beam section.
对于非消能梁段，沿全长均可能为负弯矩区，如图2所示。当负弯矩区的组合楼板在变形、温度效应或收缩徐变下，钢梁与混凝土的组合作用会使混凝土受拉。由于钢梁与混凝土主要通过螺杆式连接件和预埋螺杆连接，当连接件与混凝土间的相互约束得不到有效释放时，所产生的拉应力可能会使混凝土楼板开裂，对组合楼板的耐久性产生不利影响，同时也不利于震后修复。此外，连接件需能使非消能梁段与组合楼板能共同作用，提高其承载能力。For non-energy dissipated beam sections, there may be a negative moment zone along the entire length, as shown in Figure 2. When the composite floor in the negative moment zone is under deformation, temperature effect or shrinkage creep, the combination of steel beams and concrete will make the concrete tension. Since steel beams and concrete are mainly connected by screw-type connectors and embedded screws, when the mutual restraint between connectors and concrete cannot be effectively released, the resulting tensile stress may crack the concrete floor and affect the durability of the composite floor. It is not conducive to the post-earthquake restoration at the same time. In addition, the connectors need to enable the non-energy-dissipating beam sections to work together with the composite floor to increase their bearing capacity.
综上所述，对消能梁段组合楼板，宜保证不会发生混凝土楼板破坏，并在满足承载能力及可简单更换的要求时，尽量降低其承载能力，以达到预期的耗能目的；对非消能梁段上的组合楼板，宜考虑混凝土板可能发生的开裂。因此，偏心支撑钢框架结构目前缺少一种用于非消能梁段和可更换消能梁段上的新型组合楼板，从而制约了偏心支撑钢框架结构的推广和应用。在满足结构抗震能力及震后修复能力的同时，需保证混凝土在整个过程不被破坏，To sum up, for energy-dissipating beam-segment composite floors, it is advisable to ensure that no concrete floor damage occurs, and when meeting the requirements of bearing capacity and simple replacement, its bearing capacity should be reduced as far as possible to achieve the expected energy consumption purpose; For the composite floor slab on the non-energy dissipating beam section, the possible cracking of the concrete slab should be considered. Therefore, the eccentrically braced steel frame structure currently lacks a new composite floor slab for non-energy-dissipating beam sections and replaceable energy-dissipating beam sections, which restricts the promotion and application of eccentrically braced steel frame structures. While satisfying the structure's seismic capacity and post-earthquake repair capacity, it is necessary to ensure that the concrete is not damaged throughout the process.
