随着我国工业化进程的加快,工业设备的抗震问题越来越受到重视,而工业设备地震破坏等级划分,与建(构)筑物地震破坏等级划分一样,可作为震后地震现场震害调查、灾害损失评估、烈度评定、工业设备安全鉴定以及震害预测和设备修复等工作的基础,因此,对其研究具有非常现实和重要的意义。根据以往工业设备的震害经验、设备自身的特性和震后对企业造成的影响程度等将工业设备划分为3类,参照《建(构)筑物地震破坏等级划分》(GB/T 24335-2009)、《生命线工程地震破坏等级划分》(GB/T 24336-2009)、《石油化工企业设备地震破坏等级划分标准》(SH3050-94)、《石油化工工程地震破坏鉴定标准》(SH/T 3135-2003),并结合工业设备在日常使用过程中损坏的评定方法以及国内外有关工业设备抗震性能、震害分析和设备遭受地震后破坏程度的研究成果,对各类工业设备提出了较为科学合理的地震破坏等级划分。
With the acceleration of industrialization in our country, more and more attention has been paid to the aseismic problem of industrial equipment. The classification of earthquake damage grade of industrial equipment is the same as that of earthquake damage grade of building (structure) Disaster damage assessment, intensity assessment, industrial equipment safety appraisal and prediction of earthquake damage and equipment repair. Therefore, it is of great realistic and important significance for its research. The industrial equipment is divided into three categories according to the experience of earthquake damage in the past industrial equipment, the characteristics of the equipment and the degree of impact on the enterprise caused by the earthquake. According to the classification of earthquake damage grades of buildings and structures (GB / T 24335- (GB / T 24336-2009), Classification Criteria for Earthquake Damage Grade of Equipment in Petrochemical Enterprises (SH3050-94), Identification Criteria for Seismic Damage to Petrochemical Engineering (SH / T 3135-2003), combined with the evaluation of industrial equipment in the course of daily use damage as well as domestic and foreign related to the seismic performance of industrial equipment, seismic damage analysis and equipment damage suffered after the earthquake research results, made for all types of industrial equipment more scientific Reasonable earthquake damage classification.
