【摘要】 某地下广场部分钢筋混凝土柱柱头损伤。为了避免不恰当改造对结构性能的负面影响,对其进行了结构静力分析和抗震研究。分析了在设计静载和地震荷载作用下损伤柱对结构性能的影响,提出加固方案的重点要放在增强结构的竖向刚度上,而水平方向适当处理即可,分析结果为结构的补强加固提供了理论依据和改造参考。更多还原

【Abstract】 Some reinforced concrete column capitals of an underground structure were damaged.The static analysis and seismic study on the structure were conducted to avoid conspicuous consumption and significant negative effects due to random reinforcement.The influence on the performance of the underground structure under the static loads and seismic load were analyzed.Some significant conclusions were achieved,such as that the strengthening should focus on enhancing the perpendicular stiffness and just dealing a little on the horizontal direction of the structure,which are the references and certain theoretical basis for the reinforcement of the underground structure.更多还原
