【摘要】 采用地震反应谱法计算带伸臂结构在竖向地震作用下的反应,讨论了伸臂的加入对结构竖向地震反应的影响,探讨了适应带伸臂结构的竖向地震反应计算模型和计算方法,结果表明在伸臂框架—筒体结构的顶部,竖向地震有可能起控制作用。规范采用的计算方法偏于保守且简单易行,是适合实际应用的方法。更多还原

【Abstract】 Seismic response spectrum method was used to calculate the vertical seismic response of structure with outriggers.The influence of outriggers to the vertical seismic response was discussed and the suitable vertical seismic analysis model and method for the structures with outriggers was explored.Results show that vertical earthquake may have the controlling possibility for the structure design at the top of the frame-core tube structure with outriggers.The analysis method in the structure codes is conservative and is easy for application,and thus it is a recommended method.更多还原
