【摘要】 通过工程实例,简要介绍了超高建筑基于抗震性能的设计方法。采用Pushover分析,分别对设防烈度地震及罕遇地震作用下的弹塑性分析结果进行评估。结果表明,在不利的场地类别、设计地震分组以及抗震设防烈度下,抗震性能设计对设计结果的影响显著。更多还原

【Abstract】 Performance-based seismic design of ultra high-rise buildings was introduced briefly on the basis of a project. Pushover analysis was applied,and elastic-plastic analysis results under the intensity earthquake and the rare earthquake were estimated respectively. The results show that performance-based seismic design influences design results observably when site classification,classification of design earthquake and seismic fortification intensity are particularly adverse.更多还原
