New Guidance on Structural Reliability Principles and Methods from ASCE Publications 

Reston, Va. –The latest title from the American Society of Civil Engineer’s, Structural Reliability Guidance for ASCE 7-22, is a guidebook for practicing engineers on the structural reliability principles and methods on which modern structural standards and specifications are based. This book explores the background of and theories guiding probability-based limit state design over the last 50 years as it relates to ASCE Standard 7-22. 

This new technical report sponsored by ASCE’s Structural Engineering Institute summarizes the history and development of probability-based limit states design and covers the emergence of reliability-based codes, and system reliability and performance-based design. Also addressed are load and resistance factor design related to 7-22, specifically dead and live loads, flood, tsunami, snow loads, rain and atmospheric icing, seismic, wind, and tornado loads. 

These guidelines were developed to assist structural engineers using ASCE 7 in their work, to understand the underlying structural design concepts, and ensure the safety of the built environment.
