Abstract

The design for the Yangzhou city Changfu Group Multifunctional building structure safety degree is two, the design life of 50 years, the seismic fortification intensity is 7 degrees, seismic grade three.

This design carries through the design priniple of "application, safety, economies, beauty".According to the building design specification, hard consider each factor that effects a design.According to the structure and the building of total and the relation of minute part.

This design is based on the national current building structure design of specification for structure calculation and drawing structure construction drawing.Which main structure bearing capacity calculation of transverse load - bearing walls in.Also for structural scheme design of indoor stairs.Complete platform, bench plate, platform beam component and reinforcement calculation of internal forces and construction drawing.

In the entire structural design process, we strictly follow the requirements of relevant professional norms, refer to the relevant information and the latest standard specification, on all aspects of the design of comprehensive scientific considerations.

Is to learn two years of graduation project of this multifaceted expertise applied to the actual design, is a comprehensive summary of the two - year career.

Key words : structural design , checking calculation of bearing capacity , load calculation , calculation of reinforcement.
