摘要
针对某重油罐区机柜间和外操间采取的抗爆改造方案,使用ABAQUS有限元软件进行仿真模拟,对建筑物爆炸荷载作用下结构有限元弹塑性进行时程分析.对建筑物各面墙体、屋面的爆炸变形下支座转角、相应基础承载力、抗倾覆、抗滑移等相关性能指标进行验算,其中,墙体的最大转角为0.13°,屋面位移最大转角为 0.26°,基底最大压力Pmax≤2×fa,基底最小压力Pmin>0,M抗力>M倾覆,F抗力>F滑移.结果表明,经过改造处理后的建筑物结构安全性能满足现行国家规范的要求,可根据所采用的改造方案对建筑物进行相应抗爆加固.
Abstract
An anti-explosion renovation plan was a-dopted for the cabinet room and external operation room of a heavy oil tank area,and simulated using ABAQUS finite element software to analyze the struc-tural finite element elastic-plastic time history under the action of building explosion loads.The perform-ance indicators such as support rotation angle,corre-sponding foundation bearing capacity,anti-overtur-ning,and anti-sliding under explosive deformation of walls and roofs on all sides of the building were cal-culated.Among them,the maximum rotation angle of the wall was 0.13°,the maximum displacement angle of the roof was 0.26°,the maximum pressure of the foundation Pmax≤2×fa,the minimum pressure of the foundation Pmin>0,Mresistance>Moverturning,and Fresistance>Fsliding.The results showed that the safety perform-ance of the building structure after renovation met the requirements of current national standards,and the building can be reinforced with corresponding blast resistance according to the adopted renovation plan.
