Building shock insulation design structure and shock insulation design method thereof
The invention discloses a building seismic isolation design structure and a seismic isolation design method of the structure. The seismic isolation structure has large vertical bearing capacity, variable horizontal rigidity and horizontal elastic restoring force and meets the requirements for seismic resistance, wind resistance and the like. When the seismic isolation structure is designed, the flexible seismic isolation support is used for isolating an input path of seismic force, so that the seismic force borne by the structure can be greatly reduced, and the seismic isolation structure is safe and sound in strong earthquakes. And meanwhile, the vibration reaction of the upper part of the seismic isolation structure is close to rigid motion, and the displacement angle between structural layers is very small, so that the damage to structural and non-structural members is avoided, and the seismic performance and functional integrity of the structure are improved. Due to the fact that the horizontal rigidity of the shock insulation system is small, the period of the upper structure can be prolonged to 2-3 s or above, acceleration response generated by an earthquake of a building is greatly reduced, the shock insulation system can absorb earthquake energy and energy consumption of an additional viscous damper through non-linear deformation of the shock insulation support, the damping ratio of the system is increased, and the service life of the system is prolonged. Therefore, the acting force of the earthquake on the building can be reduced.
本发明公开了一种建筑物隔震设计结构及该结构隔震设计方法，隔震结构具备较大的竖向承载力、可变的水平刚度、水平弹性恢复力，并满足抗震、抗风等要求。隔震结构设计时以柔性隔震支座来隔绝地震力的输入路径，可大大减少结构承受的地震力，使其在强震中得以安全无恙。同时隔震结构的上部振动反应会接近刚体运动，结构层间位移角很小，避免了结构与非结构构件的破坏，提高了结构的抗震性能和功能完整性。隔震系统因水平刚度较小，可延长上部结构周期至2s～3s以上，使建筑物因地震产生的加速度响应大大减小，隔震系统同时也能利用隔震支座的非线性变形吸收地震能量以及附加粘滞阻尼器的耗能，提高系统的阻尼比，因此可降低地震对建筑物的作用力。
