Opis

This book addresses fire safety of combustible façade systems which has gained much attention in recent times due to several major fire accidents across the world where combustible façade systems had a significant role in enhancing the growth of fire. The Grenfell tower (London) fire is one of the most severe accident in this category. The book covers basic design and functional aspects of commonly used façade systems along with the materials typically used in such systems. Subsequently, it discusses the currently available testing methods at component level, intermediate level, and system level. It also provides detailed case studies of six full-scale real fire façade fire experiments that have been jointly carried out by IIT Gandhinagar and Underwriters Laboratories at the full-scale façade testing facility established at IIT Gandhinagar. The book will enable designers and decision makers to make better assessments regarding fire safety of existing and upcoming façade systems. It also serves as a guide to deciding which testing methods are more appropriate under certain conditions.

Dr. Gaurav Srivastava is an Associate Professor of Civil Engineering at Indian Institute of Technology (IIT) Gandhinagar. His research interests lie in assessment of structural and non-structural building components subjected to fire. He has led several studies in this area. While some of these studies aimed at fundamental research and development, others dealt with contemporary industrial issues. Prior to joining IIT Gandhinagar, he received his doctoral degree in Civil Engineering from the University of Minnesota and worked at the University of Notre Dame.

Dr. Pravinray Gandhi is Director of Research at Underwriters Laboratories Inc. with focus on fire safety. He has worked on research on a number of areas including smoke detection, fire growth and fire suppression. He has also contributed to the development of new fire performance test standards, fire hazard assessment methods, and has served on ASTM, NFPA, and IEC standards bodies as a subject matter expert.
