 Book on Post-Tensioned Buildings: Design and Construction

by Dr. Bijan O. Aalami

A must have reference book for engineers, students, contractors, building officials, and researchers. Provides an in-depth review of concepts and procedures of practical and modern post-tensioning design and construction. Book comes in US and International editions.
Book on Post-Tensioned Design and Construction by Dr. Bijan Aalami The book builds on over three decades of author's observation and design of post-tensioning projects in more than 35 countries worldwide. Having met and discussed with thousands of practitioners whose work encompasses the design or construction of post-tensioned projects, the author presents his observations and experience in a clear and concise format, highlighting the concepts and procedures that lead to good practice and economical designs. The book is easy to read and is accompanied by many schematics and photographs of actual post-tensioning installations.

The book comes in two versions:
The US Edition uses the US system of units (lb, in) along with the equivalent values in SI units (N, mm). It covers ACI 318/IBC and the European Code Ec2.

The International Edition covers ACI 318/IBC, EC2, and TR43 in SI (N, mm) system of units.

"I just finished reading your book and I want you to know I consider it to be the best of its class. The organization is easy to follow, and the side-by-side presentation of ACI and EC2 requirements is a brilliant addition to PT literature. Congratulations."
Gregory P. Chacos, PE
Former Director of Post-Tensioning Institute

Topics that are covered in-depth and taken to the point of practical application include:
Concepts and procedures of practical and modern post-tensioning design with an emphasis on achieving "safe" and "serviceable" outcomes
Unbonded and bonded (grouted) systems - construction technology, design procedures, and discussion of comparative features
Post-tensioned floor design with step-by-step calculation
Post-tensioned beam design with step-by-step calculation
Software and design tools with flow charts and examples
Calculation of stress losses, deflections, cracking and crack width
Application of finite element to design
Application of Building Information Modeling (BIM) to post-tensioning
Purchase

Shipment starts end of March 2014.
