Abstract

This paper is focused on the study of innovative bi-stable supports to improve the impact performance of point-fixed glass panels, for typical use in facades. To mitigate the effects of impact and reduce potential risk for people, the introduction of innovative, bi-stable, mitigation devices between the fixing system and the primary building structure is addressed. The proposed dissipative system is able to control and minimise the input force which is transmitted to the primary building, controlling the damage around the supports and preventing the detachment of the glass panels. Based on LS-Dyna Finite-Element (FE) models, the proposed protection system is designed to have a snap-through behaviour under impact. The performance of the system is quantified for two different glazing systems, which are numerically investigated under various impact configurations.
双稳支架用于定点玻璃系统冲击防护的探索性研究
本文的重点是研究创新的双稳定支撑,以提高点固定玻璃面板的冲击性能,用于外墙的典型应用。为了减轻冲击的影响和减少对人的潜在风险,在固定系统和主要建筑结构之间引入了创新的、双稳定的缓解装置。所提出的耗散系统能够控制并最小化传递到主要建筑的输入力,控制支撑周围的损坏并防止玻璃板的脱落。基于LS-Dyna有限元(FE)模型,所提出的保护系统被设计为在冲击下具有卡通行为。对两种不同的玻璃系统的性能进行了量化,并对不同冲击配置下的系统性能进行了数值研究。
