Structural Design of Jinhua Intercontinental Hotel
Jinhua Intercontinental Hotel has 23 floors above the ground,the tower is the hotel,and the podium is the banquet hall and other hotel supporting rooms.The reinforced concrete frame-core tube system is used for the main structure of the tower,and the reinforced concrete frame system is used for the main structure of the podium.According to the functional requirements and structural layout characteristics of the podium,the performance-based design is carried out,and the key components are strengthened.In view of the unfavorable conditions such as the large length-width ratio of the core tube,the discontinuity of the floor and the over-limit of the local floor displacement ratio,the envelope design of two structural systems is adopted,and the strengthening measures are taken for the key parts and components.Through optimizing design scheme of the equipment interlayer with steel structure hanging below,the problem of overrun caused by the sudden change of the vertical stiffness of the main structure is avoided.This paper innovatively puts forward the design scheme of constructing trusses in segments for high-altitude cantilevered steel structure shape.The optimization of structural layout of large-span prestressed beams is analyzed.The results show that the design structure layout of the project is reasonable,and the design optimization schemes for equipment interlayer and cantilever steel structure shape are reasonable.The economic benefits and appearance effects are good.
