the frame structure design of shunda Corporation Service Building
General Description of The Design: This is the frame structure design of Shunda Corporation Service Building. The structure is a cast-in-place reinforced concrete frame structure, which is three floors on the ground one floor underground and structural maximum height is 17.55 meters. Building shape is close to“ h”.A total construction area is 942.55 square meters. Building design service life is 50 years and fireproof rank is secondary. The seismic fortification intensity is 7 degrees. Design content is the structural design, including the determination of structure scheme, structure calculation and structural drawings. The determination of structure scheme is mainly according to the architecture diagram to selected the section size of beams and columns ，decorate the position of beams and columns , and consider the eccentric effect. Structure is mainly using PKPM structure calculation software modeling calculation to finish the reinforcement calculation of upper structure and foundation. Structure drawing is according to the calculation results to draw the reinforcement drawing of beam, floor and column, infrastructure layout and stair detail construction drawing.
Key word: cast-in-situ concrete frame structure; Structure design; Structure drawing
