"This is a great book ... easy to teach from; students can readily learn the theory from its beginnings to its practical applications; it is a course topic that will be of great value in understanding structural design during the professional life of the engineer; it is an invaluable tool to guide in the development of national design standards such as the AASHTO bridge design specification; it is logical and it is fun to go back to time and again." -Theodore V. Galambos, Emeritus Professor, University of Minnesota "... a must read for any engineer working in the civil engineering structures arena. ... provides the necessary knowledge to give structural engineers the tools they need to make better designs a priori and determine structural failures a posteriori." -Andrew D. Sorensen, Ph.D., Idaho State University, "Compared to other textbooks in this area, Reliability of Structures is particularly easy to understand. ... ideal for a first course in this topic, or if the classroom contains undergraduate students who might be otherwise lost in an advanced theoretical presentation. A particular strength is its discussion of design code development and calibration, perhaps the most important application of reliability analysis in structural engineering." -Christopher Eamon, Wayne State University
