本文系统介绍苏联和美国钢筋混凝土烟囱设计规范中温度应力计算方法。文中着重阐明它们的基本原理,对有关公式进行全面推导,同时指出其中存在的问题,并提出改进意见。本文还对美国规范补充以判别单、双值应力图形的判别公式,并对苏联规范提出计算筒身压力板带的改进公式。 This article systematically introduces the calculation method of temperature stress in the design specifications of Soviet Union and American reinforced concrete chimneys. The article emphatically clarified their basic principles, comprehensively deduced the relevant formulas, pointed out the existing problems, and put forward suggestions for improvement. This paper also supplements the U.S. specification with the discriminant formula for discriminating single and double-valued stress patterns, and proposes an improved formula for calculating the tube pressure strips for the Soviet specification.
