摘要
高层剪力墙结构智能设计包括智能建模和智能优化两个环节。目前智能建模环节缺乏梁自动化布置和荷载自动化布置；智能优化环节只考虑材料成本而未考虑施工的便捷性。此外，现有的智能设计方法均局限于单标准层的高层剪力墙结构。为此，该文提出了高层剪力墙结构多目标智能设计方法，包括多标准层高层剪力墙结构的智能建模和多目标优化。多标准层高层剪力墙结构智能建模包含剪力墙智能布置、梁自动化布置、板自动化布置和荷载自动化布置；以材料成本和施工便捷性为目标，采用分步优化策略和基于小生境技术的遗传算法对高层剪力墙结构进行多目标优化。通过实际工程算例对所提出的方法进行了验证，结果表明，所提出的高层剪力墙结构多目标智能设计方法稳定、可靠，可以较好地兼顾材料成本和施工的便捷性，并能显著缩短设计周期。
Intelligent design of high-rise shear wall structure includes intelligent modeling and intelligent optimization. At present, the intelligent modeling part lacks automatic beam layout and automatic load layout. The intelligent optimization part only considers material cost without construction convenience. Moreover, the current intelligent design methods are limited to high-rise shear wall structures with single standard floor. Therefore, this paper proposes a multi-objective intelligent design method for high-rise shear wall structures with several standard floors, including intelligent modeling and multi-objective optimization. The proposed intelligent modeling method for high-rise shear wall structures with several standard floors includes shear wall intelligent layout, automatic beam layout, slab layout and load layout. Aiming at material cost and construction convenience, a multi-objective optimization method for high-rise shear wall structure based on stepwise optimization strategy and niche genetic algorithm is proposed. The proposed intelligent design method proves to be stable and reliable through the design of a real-world shear wall structure, which can accommodate both material cost and construction convenience，and significantly shorten the design period.
