摘要
为满足石油化工厂区既有多跨钢筋混凝土框架结构建筑物抗爆加固需要,文中结合实际工程提出了在原结构外新建钢结构+抗爆板庇护罩的加固方案并采用ABAQUS有限元软件对方案进行爆炸模拟.对模拟结果进行分析后充分利用既有建筑物钢混框架结构柱承受竖向荷载,提出了一种针对多跨钢筋混凝土框架结构抗爆加固的新思路.结果表明新方案有效提高了钢架结构的总体安全性,节省了钢材用量,减少能源消耗,具有一定的经济可行性和实际参考意义.
Abstract
Anti-explosion reinforcement of existing multi-span reinforced concrete frame structure buildings is needed in petrochemical plant area.We propose a reinforcement scheme of a steel structure and an explosion-resis-tant plate shelter outside the original structure with the actual project,which is simulated by ABAQUS.Based on the simulation results,a new approach for reinforcing the multi-span reinforced concrete frame structures is proposed,utilizing the existing building's steel-concrete frame columns to bear vertical loads.The results demonstrate that the proposed scheme improves the overall safety of the structure,reduces steel usage,and decreases energy consump-tion,which has economic feasibility and practical significance.
