مشخصات طراحی پل AASHTO LRFD، واحدهای متداول ایالات متحده با اصلاحات موقت نسخه ۲۰۰۸ و ۲۰۰۹

Based on the load and resistance factor design philosophy (LRFD), this book is the result of a five-year research effort under AASHTO's National Cooperative Highway Research Program (NCHRP) Project 12-42, and a continued effort through AASHTO technical committees. This major step in improved bridge design and more accurate analysis is expected to lead to bridges exhibiting superior serviceability, enhanced long-term maintainability, and more uniform levels of safety. Since the First Edition was published in 1994, the provisions have continued to be updated and improved based on continuing research and the experience of the user community. The new specifications have been systematically tested in trial designs and have now been implemented by all 50 states, with 48 states fully implemented. Included in this electronic edition are the 2008 and 2009 Interim Revisions. Following each chapter the revisions are identified as well as linked throughout the entire book where available.
