圆形砖烟囱是我国工矿企业中非常广泛使用的一种构筑物。由于本身的结构形式及砌筑材料的特性而致使它的抗拉、抗弯及抗剪的强度都较差,在历次强震中反应都十分强烈而遭到大量的破坏。由于烟囱及锅炉房所属动力系统在工矿企业中占有重要地位,所以烟囱的破坏对震后迅速的恢复生产造成十分不利的影响。因此,有必要对现有的烟囱进行抗震能力的鉴定和分析,采取相应措施来尽量减轻震损程度。本文以唐山地震为背景,在天津调查和
Circular brick chimneys are very widely used structures in China’s industrial and mining enterprises. Due to its own structural form and characteristics of masonry materials, its tensile strength, bending strength and shear strength are all poor. In the previous strong earthquakes, the reactions were very intense and suffered a great deal of damage. Because the power system of the chimney and boiler house occupies an important position in the industrial and mining enterprises, the destruction of the chimney has a very negative impact on the rapid recovery production after the earthquake. Therefore, it is necessary to identify and analyze the anti-seismic capability of existing chimneys and take corresponding measures to minimize the degree of damage. This paper takes the Tangshan earthquake as the background and investigates
