【摘要】 钢筋混凝土框排架结构是我国火电厂主厂房常用的结构型式,结构质量、刚度分布不均匀,其整体抗震性能较差。5.12汶川8.0级地震中,某电厂主厂房遭受较大损害,电厂短期内无法正常发电。针对该主厂房钢筋混凝土框排架结构的震害特征,对震害原因进行了初步分析,由此提出了有关加强主厂房抗震措施的建议,以期提高此类特殊工业厂房的抗震防灾水平,为相关规范的修订提供参考。更多还原

【Abstract】 Reinforced concrete frame-bent structure is used widely for main building of thermal power plant;the distribution of structural quality and rigidity is non-uniform,and the earthquake resistant behavior of this structure is bad.Main-building of a thermal power plant was damaged severely in 5.12 Wenchuan earthquake.Based on the damage characteristics of the frame-bent structure,the cause of the damage was analyzed.Furthermore,several seismic prevention measures and suggestions were proposed to improve the earthquake a resistant behavior and offer a reference to correlative code.更多还原
