This book details the theory and applications of finite element (FE) modeling of post-tensioned (PT) concrete structures, and provides the updated MATLAB code (as of 2019). The challenge of modeling PT prestressed concrete structures lies in the treatment of the interface between the concrete and prestressing tendons. Using MATLAB, this study develops an innovative nonlinear FE formulation which incorporates contact techniques and engineering elements to considerably reduce the need of computational power. This FE formulation has the ability to simulate different PT frame systems with fully bonded, fully unbonded or partially bonded tendons, as well as actual sliding behavior and frictional effects in the tendons. It also allows for the accurate simulation of anchor seating loss.

This text provides a review of relevant knowledge in the area of constitutive modelling of concrete steel bonds and their interaction. It discusses the problems encountered in assembling the various elements with the purpose of constructing the model of an element made of reinforced concrete. Whether physically or empirically based, very simple or sophisticated, long-established or brand new, the models presented in this book are produced in as rational a framework as possible, and are accompanied by comments on their advantages and limitations.
This collection contains 10 papers discussing finite element analysis of reinforced concrete structures presented at an international workshop held in New York, New York, June 2-5, 1991.
