강화유리 가드 및 핸드레일 구조시스템의 실물대 실험에 의한 성능평가

Abstract

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.
