An integrated parametric structural design tool for super high-rise buildings based on Grasshopper and intelligent algorithm

Abstract

For super high-rise buildings, reasonable structural layout and design optimization help reducing the engineering costs while ensuring structural safety. However, structural designers generally create structural models through manual modelling, which is inefficient and difficult to compare and optimize structural design schemes. In order to solve this problem, after combing through the structural logic of super high-rise building structure, this research adopts the parametric design mode, and proposes an integrated design framework for parametric modelling, analysis and optimization of super high-rise building structure, and developed the design tool on the Grasshopper software. Using this tool, you can quickly create a three-dimensional structure model, and call Etabs software for structural calculations. The tool can also be used in combination with evolutionary optimization algorithms to construct a parametric optimization process for structural optimization. The effectiveness and practicability of the developed design tool is verified through a super high-rise building with frame-core tube structure. The illustrative example has been shown that the tool can help engineers quickly create and modify structural models, and the concrete material consumption can be reduced by 40% after structural optimization. The tool and design process can be extended to similar construction projects to improve the design efficiency of structural engineers and reduce the construction cost of the project.
