| 摘 要： | 钢框排架结构是我国火电厂主厂房的主要结构形式之一,但因其结构质量、刚度分布不均匀,所以对它的抗震性能研究尤为必要。采用弹性时程分析方法对大型火电厂钢框排架主厂房进行抗震分析,研究该类结构的动力特性、层间变形和层剪力等。计算结果表明:主厂房横向框排架和纵向框架-支撑结构存在较多的薄弱部位,计算分析应采用考虑扭转效应的空间模型。 |
| 关 键 词： | 框排架结构 大型火电厂 动力特性 弹性地震反应 |

| Abstract: | The steel frame-bent structure is the main load-supporting structure in thermal power plants of China,whose structural quality and rigidity are distributed non-uniformly.It is particularly necessary to research earthquake resistant behavior of this structure.The time history response analysis method was used to study the dynamic properties,the interlayer deformation and the interlayer shear of steel frame-bent structures of main buildings for large thermal power plant.The results showed that there were many weak parts in the horizontal frame-bent and longitudinal frame-supporting structures,which must be strengthened when designed.The space model should be used to consider the effect of torsion in structural calculation and analysis. |
| Keywords: | frame-bent structure large thermal power plant dynamic property elastic seismic response |
