Abstract:A comprehensive office building project adopts the cast-in-place reinforced concrete frame-shear wall structure system, the structural design of this project was introduced, and assists the architect, the design concept of floating box and folding platform was put forward, which skillfully solves various influencing factors such as functional streamline, cost control, structural rationality, etc. Considering the cost control, post maintenance, construction interface handover and local construction level and other factors, the solid web space truss structure with box section composed of reinforced concrete perforated shear wall and beam slab was used to solve the problem of overall overhanging of 12.1 meters. The cracks, deflection and comfort of the cantilever elements were checked, the construction stage simulation was carried out, and the detailed unloading scheme was formulated. The results show that the scheme of this structural design is very reasonable, economical and practical.
Keywords:reinforced concrete solid web space truss； large-span overhanging； process control； unloading scheme
