Damage of irregular-shaped sandstone balusters under real fire loading

This study aims to use architectural sandstone balusters with a concave-convex geometry to investigate the potential influencing factors during softening/destruction due to fire loading. The thermo-mechanical behaviour of large-size sandstone balusters under real fire conditions was investigated via laboratory tests and numerical simulations. It was found that the spalling of sandstone balusters undergoing extreme temperature regimes is mainly...
