Phoenix Centre Design and Construction of a Complex Spatial Structure Based on 3D Digital Technology

摘要

This study presents the design and construction of the Phoenix Centre in Beijing, China. The project has two main reinforced concrete buildings: office building and broadcasting buildings. These buildings are connected by a spatial steel shell with a complex curved surface. The project is composed of six structural parts that are not structurally independent and form a complicated system. A three-dimensional (3D) modelling software is used to build precise 3D geometric and computation models. The best architectural effects are fulfilled by designing the curved surface with the members under spatial bending-torsional conditions. A series of measurements are implemented to assure certain computation accuracy, design efficiency and construction feasibility. A smooth takeover from the complex steel design to fabrication and construction is accomplished through the information transmission technology with the Digital Project software developed based on the 3D modelling software CATIA, Rhino and Auto CAD.
