摘要

以抗震设防7度区的某古石建筑移位后连接就位工程为研究背景

探讨了采用不同连接就位方式对古石建筑加固效果的影响

并运用有限元软件SAP2000建立三维实体模型

对采用传统连接就位和隔震连接就位的古石建筑移位后进行模态分析和时程分析。对比分析结果证明

隔震连接就位方式不仅可大幅延长结构自振周期

使其避开场地特征周期

还可以在一定程度上推迟扭转振型的出现

明显减小上部结构所受地震作用

从而起到良好的减震效果;此外

隔震支座饱满的滞后曲线反映了隔震层对地震起着良好的耗能作用

在一定程度上从能量的角度保证了移位古石建筑的安全性。

Abstract

The removal connection of an ancient lithic architectur in area of seismic fortification intensity 7was regarded as a background project.The influence of different connection emplacement on the strengthening effent of ancient lithic architecture was explored and the finite element saftware SAP 2000was used to establish the 3Dstereo model.Model analysis and dynamic time-history analysis were used for traditional connection emplacement and the isolation connection emplacement.According to the contrast of analysis results

the latter connection emplacement method could not only extend the structural vibration period significantly

but also in a certain extent delay the emergence of torsional modes.Moreover

isolation connection emplacement could reduce the superstructure’s seismic response to play damping effect greatly.The plump hysteretic curve of rubber isolator also reflect good energy dissipation effect.Security of removal ancient lithic architecture is ensured in some degree in view of energy.
