Negative Positive
Title: Disappointed
Review: Disappointingly, this book is full of formula errors. This book must be used in conjunction with a formal Structural Analysis book in order to check and or correct many of the formulas given. This book does give you a broad over view of Structural Systems, but do not rely on it to be correct. My firm has both this book and the study series by Kaplan. Suffice it to say, Kaplan's Structural series is a much better study guide and so far I have found no formula errata. My Structural Engineer Colleagues can not believe that this book by Steven E. O'Hara and David Kent Ballast ever made it through any type of pre-production review with this many errors.Updated 12.15.2012: To be fair, the Kaplan book was not perfect either, but, in my opinion, was still a much better study guide.
Is the review positive or negative?
