Abstract

This project is the housing, floor space 6000m2, area 1000m2,six, Always altitude 18.6m, uses the portal frame construction, under the column the independent foundation, designs the base Service life for 50 years, the structure security rank is two levels, the earthquake resistance garrisons the intensity is 7. The architectural design is suitable in line with the \conditions suitable\principle, take the national corresponding standard, the standard as the basis, has completed the construction plane design which the design project description requires, and carried on in this foundation has set up the surface, the section plane, the architecture detail design, altogether drew the construction to attempt 4. Structural design in line with \on the vertical load collection, horizontal load collection, endogenic force computation, endogenic force combination, structure earthquake resistance,board, Liang, column, staircase, foundation isostructuralism component design. Altogether draws structure drawing 3.

Key words: Commercial housing,Portal frame construction,Independent foundation
