本文提出了一个划分钢筋混凝土排架厂房震害等级的方法。这个方法把厂房的震害分为三部分:一、抗侧力构件的震害;二、围护墙的震害;三、屋面系统的震害。划分厂房的震害等级时,先分别评定这三部分的震害,然后将它们加权进行综合得厂房的震害等级。文中根据海城和唐山地震中的200多个厂房震害实例,提出了影响上述三部分震害的参数,并研究了这些参数与震害等级的关系。最后给出了一个估计现有钢筋混凝土排架厂房遇到不同烈度地震时的震害等级的方法。
This paper proposes a method for classifying the damage level of a reinforced concrete frame building. This method divides the earthquake damage of the plant into three parts: First, the earthquake damage of the anti-lateral force components; Second, the earthquake damage of the retaining wall; Third, the earthquake damage of the roof system. When classifying the damage level of a building, the three parts of the damage are evaluated separately, and then weighted to obtain the damage level of the building. In the paper, according to the examples of earthquake damage in more than 200 factories in the Haicheng and Tangshan earthquakes, the parameters that affect the three parts of the earthquake damage are proposed, and the relationship between these parameters and the seismic damage grades is studied. Finally, a method for estimating the damage level of an existing reinforced concrete girder building when it encounters earthquakes of different severity is given.
