Fabricated steel frame beam column substructure capable of comprehensively defending earthquake and progressive collapse
The invention belongs to the technical field of structural engineering, and particularly relates to a fabricated steel frame beam column substructure capable of comprehensively defending against earthquakes and progressive collapse. Shearing force and axial tension/pressure generated between the cross beam component and the stand column component are borne through the multifunctional mechanical hinge, the damage degree of the substructure is reduced, and the safety of the substructure is guaranteed; under the action of large earthquakes and giant earthquakes, the multifunctional mechanical hinge rotates and generates plastic deformation to consume energy and consume energy generated by the earthquakes, meanwhile, the pre-tightening suspension component is tensioned, progressive collapse is avoided, and the progressive collapse resistance of the substructure is improved; when the substructure is close to collapse under the action of an earthquake, the pre-tightening suspension component suspends and bears the cross beam component, so that the vertical pulling capacity of the substructure is improved, and the consequence of continuous collapse of the substructure is relieved.
本发明属于结构工程技术领域，尤其涉及一种综合防御地震和连续倒塌的装配式钢框架梁柱子结构，本发明的钢框架梁柱子结构在正常使用阶段和中、小震作用时，通过多功能机械铰承担横梁构件以及立柱构件之间产生的剪力以及轴向拉/压力，减轻子结构结构的受损程度，使子结构结构的安全得到保障；在大震和巨震作用时，多功能机械铰发生转动，产生塑性变形进行耗能，消耗震动产生的能量，同时预紧悬挂构件拉紧，避免发生连续倒塌，提高了子结构的抗连续倒塌能力；当子结构在地震作用下接近倒塌时，预紧悬挂构件对横梁构件进行悬挂承载，增加了子结构的竖向拉结能力，减轻了子结构连续倒塌的后果。
