交通部永济电机厂锅炉房45米砖烟囱,采用“M”形薄壳基础,71年下半年设计并施工,我局一处二段领导、工人和技术人员参加了该基础的设计施工,茲介绍如下。一、设计概况设计采用了“冶金建筑情报资料”第7005号(70·10·31)介绍的锥壳基础简化设计计算法,即在薄膜理论的基础上,将壳面的弯矩、扭矩、切力均略而不计。除强度计算外,进行裂縫宽度验算不超过
Ministry of Communications Yongji Electric Machinery Factory boiler room 45 meters brick chimney, the use of “M” -shaped shell foundation, design and construction in the second half of 71, I Bureau of a leadership, workers and technicians to participate in the design and construction of the foundation, Here is the introduction. First, the design overview Design used in the “Metallurgical Construction Information” No. 7005 (70.10.10) introduced cone shell simplified design and calculation method, that is based on the film theory, the shell surface bending moment, torque, Cuts are slightly not counting. In addition to the strength calculation, the crack width check does not exceed
