摘要
设备的连接部位不牢及地脚螺栓强度不足而造成的安装在楼层上的设备破坏程度一般比地面上的设备震害严重。对安装在楼层上的设备模型进行探讨,采用等效侧力法及时程分析法对安装在楼层上的设备———蒸发式冷凝器的地震作用进行计算,并对其抗震性能进行验算。实例表明,采用的计算方法是可行的、实用的。此蒸发式冷凝器是安全可靠的。
The seismic damage of floorsupported equipments was more serious than those fixed on ground.The reason by which equipment was destroyed was loose joint or insufficient intensity of the bolt. A calculation model of floorsupported equipment was discussed.And the seismic force of floorsupported equipments——evaporative condensers was carried out using equivalentsideforce method and the timehistory analyzing method.The aseismatic capability of the equipments was checked.The practice examples show the rationality and practicability of the adopted method.The evaporative condenser was safe.
