在石油和石油化工企业中,圆筒型立管式工业炉在生产中占有特殊重要的位置.这种设备是见明火的设备,一旦发生地震灾害,容易引起火灾.所以,对这种设备的抗震设计和对当前的抗震加固设计,都必须给予足够的重视.这种设备是由炉顶烟囱、对流室、辐射室和炉底柱所组成,就其外形来说,类似于变截面的塔型结构物(见图1). In oil and petrochemical companies, cylindrical riser industrial furnaces occupy a particularly important position in production. Such equipment is a device that sees open flames. Once an earthquake disaster occurs, it can easily cause fire. Therefore, for such equipment, Seismic design and current design of seismic strengthening must all be given sufficient attention. This equipment is composed of a roof chimney, a convection chamber, a radiation chamber and a hearth column, and in terms of its shape, it is similar to a variable cross-section tower. Structures (see Figure 1).
