石油化工抗爆建筑物结构设计应用

THE DESIGN APPLICATION OF BLAST RESISTANT BUILDINGS FOR PETROCHEMICAL FACILITIES

由于石油化工行业工艺复杂化、装置大型化、规模扩大化等因素,化工设备出现爆炸事故的风险越来越高,设备爆炸时对化工建筑产生较高的冲击波荷载,为确保结构以及人员安全,结构应具有相应的抗爆能力。参考美国土木工程师协会编写的《石油化工抗爆建筑设计》介绍抗爆设计目标、爆炸荷载确定、动力材料响应准则和强度、结构可靠度指标、动力分析方法等内容,以构件计算实例介绍抗爆设计步骤。

Petrochemical processes have become more complex and plants have increased in size,thus increasing the risk of accidental explosions,so the requirements for design of blast resistant are higher and higher.To protect lives and buildings, structures should have adequate resistant capacity according to objective blast loads.It is introduced the ASCE's 'Design of Blast Resistant Buildings in Petrochemical Facilities',including the design objective,blast load,dynamic material strength and response criteria,dynamic analysis method,etc.also the blast resistant design procedures are described with a example.
