Research on Key Design Techniques for Large-Span Structure on Slope
The Hengli Emergency Command Center is flanked by mountains on three sides,forming two high and low embedding ends,resulting in a distinctive high-rise building structure supported by foundations with two or more different elevations.The structure is effectively connected to the mountain by setting steel truss connecting components,simplifying the embedded end of the floors under the upper embedding end and simplifying the boundary conditions of the structure.The bearing capacity and stiffness of the structure under rare earthquakes are verified using elastic-plastic analysis.Simultaneously,an integrated analysis technology of the mountain and main structure is employed to determine the internal forces of the connecting components between the main body and the mountain under real earthquake conditions,and verify their reliability.For large-span structures,a new type of prestressed steel reinforced concrete beam has been adopted,which effectively reduces the structural weight,correspondingly reducing the beam height,and significantly improving structural efficiency.This project represents a unique mountainous building,and the structural design adopts innovative treatment methods,which can provide a reference for similar engineering projects.
