Influence of Structural Sealant Joints on the Blast Performance of Laminated Glass Panels
Publication: Journal of Performance of Constructed Facilities

Abstract
This paper investigates the influence of structural sealant joints on the blast performance of laminated glass (LG) panels, using a comprehensive numerical procedure. A parametric study was carried out by varying the width, thickness, and the Young’s modulus () of the structural silicone sealant joints, and the behavior of the LG panel was studied under two different blast loads. Results show that these parameters influence the blast response of LG panels, especially under the higher blast load. Sealant joints that are thicker, have smaller widths, and lower values increase the flexibility at the supports, and hence increase the energy absorption of the LG panel while reducing the support reactions. Results also confirmed that sealant joints designed according to current standards perform well under blast loads. Modeling techniques presented in this paper could be used to complement and supplement the guidance in existing design standards. The new information generated in this paper will contribute toward safer and more economical designs of entire facade systems including window glazing, frames, and supporting structures.
