房屋钢结构复习总结(国外英文资料) Chapter 1 light gate steel frame structure The concept, composition, and system of single layer door steel frame structure Concept: to light h-beam welding (such as cross section or variable cross-section), hot-rolled h-beam (cross section), or cold bending thin-wall steel is composed of lattice type solid-web door frame or door frame as the main load-bearing skeleton, with cold bending thin-wall steel (slot type, edge groove type, Z, etc.) to do purlin, wall beam; To make roofing and metope with pressing metal plate (pressure type plate, pressing aluminum plate); Polystyrene foamed plastic, rigid polyurethane foam plastics, rock wool, mineral wool, glass wool, etc as the thermal insulation material and properly set up to support a lightweight building structure system. Composition: beams, walls, purlines, walls, supports, roofing and wall panels 2. The door frame beam and column component more non-uniform welding h-type section, single span steel beam - column nodes using just answer, mostly just answer and articulated and multi span. The foot of the column can be connected to the foundation or rearticulated. The characteristics of single layer steel frame structure and reinforced concrete structure: A: the quality of light. The amount of steel used in the steel frame of a single door frame is 10 ~ 30kg/m2. In the case of the same span and load conditions, the self-weight is only about 1/30 ~ 1/20 of the reinforced concrete structure. B: the industrialization is high and the construction cycle is short C: the overall economic efficiency is high D: its flexible. The column distance is 6 meters, and when the 12 meter column is used, the bracket and the wall column should be set. Steel frame for variable section (change: change of section height, width and width) Under the effect of vertical load, the frame Angle area (beam column node) has a large negative bending moment, and the frame beam span has a large positive bending moment. The hinged frame
