Design of structural glass fitting for seismic condition

Abstract

The use of point bolted system to hold the glass panes of a building is becoming very popular nowadays. Many Architects are beginning to substitute the curtainwall or framed glass wall with the frameless, dot point types. It makes use of stainless steel glass fittings to hold these glass panes and in elevation, it provides a clear, transparent effect. Most current glass fittings have all fixed arms, which are used for transferring loads from facial glass panes to the structural members. They are commonly used in nonseismic zones countries and are not designed to use in seismic conditions. With the new system, which provides more flexibility, the arms on the fittings are made to articulate which enable the glass to move freely during an earthquake. In order to do that, we are required to have a clear understanding of the seismic design process and to be able to perform steps to establish the movement response parameters.
