Abstract
Glass façade construction is increasing at a rapid rate with more attention to aesthetics, energy efficiency, green concept, etc. but the fire safety factor has completely been neglected. A high-rise façade is a very crucial element in case of a fire incident, poses a greater fire hazard. However, they can easily allow the fire to transfer from lower floor to upper floors of the building through the gap present in between the slab edge and glass façade. This study promotes fire safety in the façade structures. The study is based on cellulosic fire and mainly concentrates on the chimney effect, which is very common in residential, commercial, and institutional buildings, etc. Following fire safety, passive fire protection is considered for the study. The study says in the buildings with glass façade, proper compartmentation must be adopted by ensuring proper fire stop** done at spandrel sections in compliance with test conditions. This can be implemented with proper installation of fire stop in all necessary areas such as unsealed openings and joints to prevent fire spread. A real spandrel of a building has been analyzed and re-drawn in AutoCAD software as per fire safety norms of ASTM E2307 and further engineering judgements have been made for the same as per International Firestop Council guidelines which are also reflected in IS 12458-2019. The study also includes basic analysis on cause of some major fire incidents in India, key points on building fire safety provision of passive fire protection. NBC-2016 is also referred to get an insight about the important clauses which promotes the façade fire safety.
