The previous version of this book was prepared based on some of the standards that now are superseded by the later version such as ACI 318-14 and NDS 2015. AISC 13 edition still is used for solving the steel problems. Two individual PEs have checked the problems to ensure the solutions are correct. Our intention is to assist Civil and Structural PE candidates to be prepare for their professional licensing exam. It is clear that we won’t be able to cover everything however we try to use our past experiences to come up with more practical type of problems which you may see it in the actual exam. We have used Matchcad for solving the problems and checked them several times this time to ensure copy-paste into word file dose change the units and formulas.
 
We really thank you for your input for improving the upcoming versions and will more appreciate for contacting us via our email: kourosh.akbari@kngpllc.com for any specific comments instead of posting it to social media. In this way we would know exactly which part of the problems you are referring to and it would be much easier for us to address the issues for the future updates. Once again thank you.
