Abstract

The construction industry is one of the sectors with the highest environmental impact, yet it constitutes an important part of the global economy. Therefore, minor improvements in this sector can lead to substantial global benefits. Structural optimization protocols offer promising solutions to this challenge, especially for gridshell structures. Given the complexities involved in constructing gridshells, optimization techniques can play a crucial role in enhancing design by reducing material usage, and improving construction efficiency. This paper presents a methodology for the optimization of gridshell structures using the NSGA II optimization algorithm, combined with the improved Multi-body Rope Approach (i-MRA) form-finding method. The primary objective of this methodology is to minimize the variety of structural elements, reduce material consumption, decrease production waste, and ensure adherence to structural verification standards. This methodology provides an efficient approach for the conceptual design of gridshell structures.

可持续性网格壳的寻形与元启发式多目标优化方法

建筑业是对环境影响最大的行业之一，但它构成了全球经济的重要组成部分。因此，这一部门的微小改进可以带来巨大的全球效益。结构优化协议为这一挑战提供了有希望的解决方案，特别是对于网格壳结构。考虑到网格壳结构的复杂性，优化技术可以通过减少材料使用和提高施工效率来提高设计水平。本文提出了一种基于NSGA II优化算法的网格壳结构优化方法，并结合改进的多体绳法（i-MRA）寻形方法。该方法的主要目标是尽量减少结构元素的多样性，减少材料消耗，减少生产浪费，并确保遵守结构验证标准。该方法为网格壳结构的概念设计提供了一种有效的方法。
