报告简介：

American Association of State Highway and Transportation Officials (AASHTO) released its very first edition of Load and Resistance Factor Design (LRFD) Specifications in 1994. Since then, it has gone through six revisions (1999, 2004, 2007, 2010, 2012 & 2014). In this presentation, the fundamental framework of AASHTO LRFD Specifications (probability theory & reliability theory) will be presented first, followed by the main features of the specifications including load and resistance factors, limit states, live load model, live load distribution, stability checks for earth walls, and advantages. Along the way, some research issues will be discussed. The purposes of this presentation are to disseminate the new bridge design methodology and to stimulate interest from the audience with the hope of possible future research collaboration.
