Edge Capacity of Through-Bolted Laminated Glass (Preprint)

摘要

This paper presents the results of testing and analytical developments sponsored by the U.S. Department of State to investigate the capacity of through-bolted laminated glass edge supports. Design equations and supporting test data are presented that capture the capacity of the through- bolted laminate material in reaction to in-plane membrane induced loading. A simple analytical treatment of edge clamping force is presented. Preliminary test data supports the validity of the clamping force calculation. The feasibility of designing through-bolted connections that are capable of reaching capacity for the full post-crack in-place membrane tension of laminate materials is demonstrated. Laminate coupon testing and laminated glass drop hammer testing was executed by the Force Protection Branch of the Air Force Research Laboratory (AFRL) at Tyndall Air Force Base, Florida. Laminate component testing and analytical developments were conducted by Southern Research Institute in Birmingham, Alabama.
