Design of concrete frame structure of parking garage of M2 Nanjing commercial building (2)

abstract

The project is an eight story frame structure house with a total construction area of 12000 square meters. The architectural drawing of the project is shown in the annex. Thefloor height, basic wind pressure value, seismic fortification intensity, design basic seismic acceleration value, site soil type and design earthquake grouping are shown in Table 1. Facade decoration and floor can be determined according to the architectural drawing. The load value shall be taken according to the load code for building structures or the actual situation of buildings. The design includes: structure calculation and construction drawing. The results are compared with each other.

The design includes: design calculation and design calculation; Firstly, the structure is calculated, and then the calculation results are compared.Manual calculation content: material selection, structural layout and determination of section size adopt beam group method to calculate a frame (4-axis), consider 5 kinds of internal force combinations, and select the most unfavorable combination for independent foundation design of beam column reinforcement design.Calculation content: the PKPM model is used to calculate the line load between beams, and then the final design results of concrete structure (beam, column and slab reinforcement) are analyzed and calculated by SATWE according to the calculation results of SATWE.This design is composed of eight parts: general description of structural design, general layout, foundation test, column reinforcement drawing, floor reinforcement drawing, floor reinforcement drawing and stair design drawing.In short, the structural design follows the principles of safety, economy and practicality, and is carried out in strict accordance with relevant professional standards, the latest national requirements and relevant data.

Key words: Structural design; Frame structure; Concrete; Reinforcement Calculation
