N21 Zhongtian Iron and Steel Running the Bulls Experimental School Steel Structure Canteen Structure Design
Abstract
This graduation project is "N21 Zhongtian Iron and Steel Running the Bulls Experimental School Steel Structure Canteen Structure Design", the design mainly includes two parts, the upper structure of the building using steel structure frame structure, the lower part of the column under the independent foundation. The construction area of the project is about 6000 square meters, the building plane rules, a total of four layers, the bottom layer is 4.5 meters high, the rest of the layers are 4.2 meters. Class C buildings with a design base period of 50 years. The seismic fortification intensity is 7 degrees, the design basic seismic acceleration value is 0.10g, the design earthquake is grouped into one group, and the site soil is classified as Ⅲ class.
The design content of "N21 Zhongtian Iron and Steel Running the Bulls Experimental School Steel Canteen Structure Design" includes: structural calculation and construction drawing. Structural calculation is calculated first by hand and then by hand, and finally by hand compared with electric calculation. Hand calculation content: material selection, structural layout and determine the beam and column section size; Take a frame (③ axis) for vertical load (dead load, live load, gravity load) calculation and internal force analysis (using bending moment secondary distribution method), horizontal load (seismic action) calculation and internal force analysis (using D value method); Considering the combination of five kinds of internal forces, select the most unfavorable combination for beam, column member checking calculation; According to the results of internal force combination, the node design is carried out. Independent foundation design under column; Stair design.
Computer content: modeling with PKPM software, and then SATWE analysis calculation, SATWE results to view, determine whether the structure layout is reasonable and adjust, and finally draw the concrete structure construction drawing.
There are altogether eight construction drawings, including: general description of structural design, foundation layout drawing and foundation sample, column planing method construction drawing, standard beam planing method construction drawing and standard slab planing method construction drawing, roof beam planing method construction drawing and roof planing method construction drawing, stair section drawing and reinforcement drawing. In short, the structural design in accordance with the principles of application, safety and economy, in strict accordance with the relevant professional standards and the requirements of the latest national standards and relevant information design calculation.
Key words: steel structure design; Frame structure; Internal force analysis
