文档介绍：Steel structure workshop design I. Structure and column grid he structural system Single-layer workshop steel structure system is posed of horizontal structure and vertical structure of the system. Horizontal system is bent. Name can be referred to as the frame bent frame, frame, etc. Can also be called articulated bent and bent. Specific situation according to the technological requirements, plant, stiffness requirements, selection of structure stress distribution, etc. Longitudinal system generally consists of columns and its support, bracket, crane beam and the brake beam or truss, wall beam, etc. B. Column grid Column grid should be according to the technological requirements, the economic column spacing and determine the span, beautiful buildings, etc. prehensive economic indicators, including basic cost, steel consumption, production installation difficulty and schedule etc. Span generally according to the requirement of process. Through many years design experience, the economic column spacing is: 24 m used heavy-duty workshop foundation is poor, medium workshop foundation is poor in 18 m, 15 m, light factory building with 12 m; The foundation is better when the plant general appropriate USES 12 m and 18 m column spacing. C. Workshop temperature expansion joints The transverse temperature expansion joint with double column expansion joints in general. Workshop of exp
