ABSTRACT

In early architectural schematic design phase of a 400m super high-rise building, the architect provides a variety of schemes with different facade inclination angles, from which structural engineers need to select the optimal scheme to meet the requirements of building safety and economy. However, due to the tight time and heavy workload of structural scheme selection, structural engineers are facing great challenges to find the optimal scheme in the expected time. Therefore, an integrated scheme comparison- and-selection method based on parametric modeling technology and multi-level fuzzy comprehensive evaluation is proposed, which realized the rapid modeling, analysis and scheme evaluation of the 400m super high-rise building automatically. The effects of different inclination angles on the overall performance and economy of the structure are accurately investigated. According to the analysis results, with the increase of facade inclination, the minimum shear weight ratio and stiffness weight ratio of structure first increase and then decrease, and the basic period and maximum story drift rotation first decrease and then increase. The proposed method greatly reduces the workload of structural scheme comparison and selection in the preliminary schematic design phase, improves the work efficiency, and has significant engineering application value.
