【摘要】 应用消能减震技术进行结构抗震加固分析中,以往是用有效阻尼比模拟阻尼器的作用。根据开孔式加劲阻尼器的特性,在进行加固结构的抗震推覆(pushover)分析中,提出了一种新的阻尼器分析替代模型,将阻尼器在大震下的力学行为用有效塑性铰进行模拟。通过消能减震技术在某文物保护性建筑抗震加固分析中的应用,阐述了该模型在结构抗震加固推覆分析中的应用方法。此方法不但直观,且能更有效掌握阻尼器和消能结构在大震下的行为,还能对结构的抗震加固效果进行有效评定。更多还原

【Abstract】 Based on the characteristic of HADAS, a new substitute model of damper analysis which can effectively simulate the behavior of dampers during strong earthquakes with the effective plastic hinge, is put forward. By applying energy dissipation tech. to the anti-seismic reinforcement of one certain protected historical structure, it elaborates the using method of said new model in the pushover analysis. This new analysis method can be more directly perceived through the senses and will help the engineer effectively understand the behavior of dampers and structures during strong earthquakes. In addition, the performance of anti-seismic reinforcement can be effectively evaluated and judged by this analysis method.更多还原
