The effect of glass stiffness on the distribution of heat on the glass panel

Abstract

The glass panel is the building material generally exposed to heat such as solar radiation, energy consumption, climate change and fire condition. Solar radiation has always been a natural thermal load impact on the building structure and materials such as glass panels. The heat generated by the sunlight affecting the stiffness of the glass panel is shown by the thermal coefficient, heat transfer, crack propagation, and thermal shock investigated by the previous researchers. Hence, this research will study the different thicknesses of the glass panels that impacted the stiffness of the glass panels. Therefore, the objectives are to determine the effect of the different thicknesses of the glass panels subjected to the thermal condition and to investigate the effect of glass stiffness in terms of stress and temperature change subjected to the heat. The solar radiation was chosen as a thermal load by the emissivity value of 1 and 313.25 K of its current temperature impacted the tempered glass panel type to define the stiffness of glass in varied thickness for the dimension of 1 m x 1 m area. By using Finite Element Analysis software that is ABAQUS, the model was set up to perform analytical research. The results show of comparing the values of deformation by 3 nodes that the tempered glass panel of 10 mm and 11 mm thickness with a dimension of 1 m x 1 m had the higher stiffness due to the lowest deformation values that were imposed by the heat distribution while 5 mm and 8 mm give the lowest stiffness of the glass panels. Besides that, thermal stress and absorption of the heat into the glass panels do not significantly impact the stiffness of the glass panels. In a conclusion, the glass thickness affected the stiffness of the glass panels when subjected to the heat by looking at the value of its deformation under the heat distribution and be able to suggest the best thickness to be used under the heat distribution.
