In order to increase transparency in buildings, structural elements made of laminated glass are being developed. The recent technological improvements in terms of material research, fabrication processes, and construction techniques, are creating new design opportunities for laminated glass structural elements. For laminated glass, the post-breakage strength and safety are important because of the brittle nature of glass, especially in structural applications. The connection between elements is a critical part, because high loads are concentrated in small surfaces, leading to local peak stresses. In this review, different connection types for structural glass elements are presented, and their performance is evaluated. Most common connection types are mechanical, adhesive, and laminated. The main goal of this review is to compare the experimental results obtained from different types of connections, evaluating the type of test, the materials used, the pre- and post-breakage performance, the failure mode, and the influence of ageing factors and load duration.
