Calculation and Analysis of Anti-explosion Renovation Structure for Cabinet Room and External Operation Room in a Certain Heavy Oil Tank Area
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.
