摘　　要：为了研究多连拱防护门在化爆荷载作用下的动力响应特性，采用ABAQUS有限元软件分别建立了平板防护门和多连拱防护门有限元模型，并对其在4种等效化爆荷载作用下的结构响应作了对比分析。结果表明：在满足设计要求的前提下，多连拱防护门的位移与平板防护门基本一致，但反弹力明显小于平板防护门的，且用钢量比平板防护门的减少33．4％，具有显著的工程实际意义和经济价值。In order to study the dynamic respense of multi-arched protective doors subjected to chemical explosion, the corresponding numerical simulation was conducted using the finite element program ABAQUS. The finite element models of a fiat protective door and a multi-arched protective door were established. And then, the dynamic response of them was compared under four equivalent chemical explosions. The results show that the rebound force of the multi-arched protective door is significantly less than that of the fiat protective door, and steel consumption is reduced by 33.4% under the design requirements. It has a certain practical significance and economic value.
