Structural Performance Evaluation of Tempered Glass Duard and Handrail System Based on Full-Scale Test

This paper summarized full-scale test results on tempered glass guard and handrail systems unreinforced with structural framework. This cantilevered system has low redundancy and glass material itself is brittle. Depending on the connection type, stress concentration at the connection appears unavoidable. The resulting failure mode is very sudden and dangerous so that the structural safety should be controlled with a higher margin. Two connection types of frequent use were tested and evaluated based on full-scale test specimens. Specimens with bolted connection showed inferior performance due to brittle fracture arising from stress concentration while plastered connection specimens exhibited excellent performance even under cyclic loading.이 연구는 2005년도 (주)동신씨지이의 연구비 지원에 의한 결과의 일부임
