摘要

网壳结构三维隔震是备受关注的研究热点之一。已有的研究聚焦于被动型三维隔震装置，其在竖向的性能参数无法实时调控。为解决这一问题，将负刚度磁流变阻尼器（magnetorheological negative stiffness dampers，MRNSDs）与预压弹簧装置（prepressed spring devices，PSD）并联，形成一种可调节阻尼力的竖向隔震装置（MRDNSD-PSD）。面向延长受控结构竖向自振周期的目标，建立了MRNSD的控制策略及其实施方法，利用其模拟了该控制装置的滞回响应。以某周边支承单层球面网壳作为研究对象，将含有MRNSD-PSD的半主动三维隔震系统、两种不同的被动三维隔震系统分别用于提升该结构的抗震性能。通过数模模拟，对上述受控和无控结构进行了地震响应分析。数值结果表明，三种隔震系统均可有效降低结构地震响应，但半主动隔震系统较被动型隔震系统能够提供更优的竖向加速度和竖向位移控制效果。

Abstract

Three-dimensional (3D) isolation of lattice shell structures is a vital research focus at present. Previous studies concentrated on passive 3D isolation bearings without adjustable real-time control capacities. To address the issue, magnetorheological negative stiffness dampers (MRNSDs) were combined with prepressed spring devices (PSDs) in parallel to form a vertical isolation bearing (MRNSD-PSD) with an adjustable damping force. Based on an objective of extending natural period in the vertical direction, a set of control strategy and implementation method of MRNSDs were established, which was used to simulate the cyclic behavior of the proposed damping device. A single-layer spherical lattice shell with surrounding columns was used as a prototype structure. A semi-active isolation system with MRNSD-PSDs and two different passive isolation systems were separately used for the target structure to improve its seismic behavior. The seismic responses of the controlled and uncontrolled structures were analyzed via numerical modeling. The simulation results indicate that all the three different isolation systems are effective in mitigating structural responses, whereas the semi-active isolation system provides superior control effects on vertical accelerations and displacements to the passive isolation systems.
