The framework design of Hengyuan Trade Center

General Description of The Design: The design of Hengyuan Commerce & trade center frame structure design, structure type of cast-in-place reinforced concrete frame structure, a total construction area of 10275  (in the construction area of 9022 , underground construction area of 1253 ).The building height and layer: this project on the 8 floor, underground 1 storey building height of 30.40 meters. The architectural design service life is 50 years, refractory grade two, seismic fortification intensity is 7 degrees.Design content for the structural design, including the structure of the program design, structural calculation and structural mapping. The structure scheme is determined mainly according to the construction drawing to select the section size of the beam and column, and the position of the beam column is arranged, and the influence of eccentricity is considered.The structure calculation is mainly software modeling and calculation of combining reinforcement calculation of superstructure and foundation structure calculation by using PKPM. Structure drawing is mainly based on the calculation of drawing slab column match tendon picture, infrastructure layout and detail stairs construction drawings.

Key word: cast-in-situ concrete frame structure; Structure design; Structure drawing
