【摘要】 RC(钢筋混凝土)框排架结构是火电厂主厂房一种常用的结构型式,因承载的设备种类繁多,运行参数复杂,使其整体布置不规则,空间性能差,质量、刚度分布不均匀,导致结构体系的抗震性能较差。通过分析大震中RC框排架结构主厂房震害特征的共性,提出加强主厂房抗震设计的建议。更多还原

【Abstract】 RC frame-bent structure is used widely for main building in thermal power plants,irregular integrated layout,poor spatial performance,uneven quality and rigidity cause poor seismic behavior of the structure system with multiplicity equipment types and complex operation parameters.The safety of main building relates to normal supply of power energy in thermal power plant with lifeline engineering,by reasonable seismic design to ensure the safety.The suggestions presented to improve seismic design of main building provide references for related code modifications and rules establishment by analyzing the generality of damage characteristics on main building with RC frame-bent structure in strong earthquakes.更多还原
