Wind-Induced Structural Response of Skylights: A Eurocode-Based Assessment

Abstract

The installation of structural glass systems, such as skylights and curtain walls, may improve the aesthetic and functional value of a building. These attractive systems have practical benefits like increased efficiency and lower maintenance costs. The importance of structural analysis and design in developing safe and dependable structural glass systems is underscored by this study, which thoroughly evaluates various skylights installed at a height of 15 m located in Doha while subjecting them to a 1.6 kPa wind load. The temperature loading is determined by assuming an initial temperature of 10°C and an ultimate temperature of 50°C. Therefore, the temperature variation is ±40°C. Several acceptance requirements have been met. It is crucial to adhere to design requirements and execute extensive performance testing and verification to guarantee the safety of structural glass buildings. The research also highlights the significance of using sound foundation design and anchoring methods on-site. The findings of this study might serve as a helpful reference for façade engineers responsible for designing structural glass structures, as it highlights the significance of careful analysis, design, and verification in ensuring the safe and dependable performance of such architectural features in a wide range of buildings. The study indicates that proper design regulations and standards, coupled with the use of specialist software tools, precise three-dimensional (3D) models and simulations, and extensive performance testing and verification, are essential in guaranteeing the safety and dependability of skylights. It has been found that the final design of the skylights is safe and structurally sound; this includes the use of fully tempered double glazed unit (DGU) glass of 6 mm (inner lite) + 16 (air gap) + 13.52 (6+1.52+6 outer laminated lite), 120 mm deep Mullions and transoms, and appropriate anchoring mechanisms using chemical anchors.
