目前我国计算砖砌烟囱所采用的方法,均未曾充分考虑砌体的承载能力及受拉环箍与砌体的共同作用,以致无论在砌体截面之选择与环箍或配筋用量上都有过份的消耗。 本文系根据文献[8]～[12],介绍砖烟囱的新计算法,并结合工作中体会进行了讨论,砖烟囱在工业与民用建筑中采用甚广,按本文计算方法比旧法计算可节省环箍用钢量50～67％,筒壁减薄15～20％,值得提供给大家研究参考。
At present, the methods used in the calculation of brick chimneys in China have not fully considered the bearing capacity of masonry and the joint action of pull collars and masonry, so that both the selection of masonry sections and the amount of hoops or reinforcing bars have been used. Excessive consumption. This article is based on the literature [8] ~ [12], introduces the new calculation method of brick chimney, and combined with the work experience to discuss, brick chimney is widely used in industrial and civil construction, according to the calculation method of this paper can be saved than the old method The hoop steel volume is 50 to 67%, and the wall thickness is reduced by 15 to 20%. It is worth providing reference for everyone.
