Abstract

In finite element analysis of the prestressed concrete (PSC) shell structures, preparation of the tendon data including the intersection points with the shell elements is very time-consuming. In this respect, automatic generation scheme of these points can be very effective. The purpose of this study is to propose an efficient method that can improve the existing automatic generation algorithm of the tendon data for the shell elements. Here, some useful techniques are proposed that can accelerate the procedure and overcome cases of singularity. Numerical examples are presented to verify the enhanced speed as well as the accuracy of the proposed scheme in comparison with the previous algorithms.
