Experimental and Numerical Studies on the Failure of Curtain Wall Double Glazed for Radiation Effect

Abstract

National and international standards for curtain wall glass are focused on wind pressure and insulation performance, but disasters such as fires and earthquakes are not considered. Failure of curtain wall glass during a fire in a skyscraper increases the loss of lives and property due to the spread of fire. Therefore, the fire resistance of curtain wall glass should be investigated, and technology to prevent glass failure should be developed to prevent fire damage due to spreading fire. It is important to predict the starting point of cracks and the cause of glass failure to prevent it effectively using the limited water in a skyscraper. In this study, double glazed glass was exposed to a radiator in an experiment performed to analyze the thermal characteristics. The results show that glass that was not directly exposed to high temperature and pressure was broken. To identify this failure case, numerical analysis was performed. Three glass specimens were installed in an ISO 9705 room and exposed to radiation using a radiator, and a thermocouple was used to measure the temperature on the surface of the glass. Widely used double glazed glass was analyzed for weakness to fire.

Seismic and Energy Performance Evaluation of Large-Scale Curtain Walls Subjected to Displacement Control Fasteners

“…Due to this problem, studies on seismic design and reinforcement of non-structural elements, such as curtain walls and windows, have recently been conducted in Korea, and related standards are being improved. Nonetheless, the level remains insufficient [26][27][28].…”

Investigation of thermal breakage and heat transfer in single, insulated and laminated glazing under fire conditions

“…Nam et al [23] In the present work, a total of ten full-scale experiments were conducted to explore the breakage behavior of the three most typical types of glazing: single coated, insulated and laminated glass. A pool fire was used as the heat source.…”
