【摘要】 计算分析无力矩油罐在强烈地震时的安全度,采用Housner简化计算方法验算油罐的稳定性,综合考虑液体静压荷载、水平地震荷载及由垂直地震加速度引起的罐体和液体压力增值,对无力矩顶油罐进行罐体抗震的稳定验算、强度验算及油罐上部节点强度验算.通过算例测定,现行标准不能使油罐在强烈地震时有可靠的稳定性,应对无力矩顶油罐增加相应措施才能达到抗震要求.更多还原

【Abstract】 The stability and strength checking methods for the oil tank are proposed by means of simplified Housner calculation method,in which the static load of liquid,horizontal earthquake loads and the increments of the tank weight force and the liquid pressure caused by vertical earthquake acceleration are considered.The checking results of the stability and strength of the tank body and the strength of the upper node of the oil tank show that the current standards can not provide the reliable stability for the tank during strong earthquake,and therefore,necessary measures need to be adopted for meeting the requirement of anti-earthquake to the tank.更多还原
