The construction industry is evolving at mind-blowing speed. Using the latest available technology and software solutions is essential to reduce the efforts of engineers and remove the burden of repetitive tasks. This is where API comes in.

In July 2020,  we hosted a webinar, “How I Design Bridges: Static Analysis of Cable-Stayed Bridges," by Sam Li, Senior Structural Engineer/CaSE Design, Australia.

Mr. Sam Li goes through the complete process of performing static analysis of cable-stayed bridges, and we believe this knowledge will help various global structural engineers with their ongoing projects.

## Elongations of Prestressing Steels

When we build prestressed concrete structural members, which is a frequently used material for bridges worldwide, the benefit in material savings and reduction of dimensions is guaranteed only when it is built correctly. Structures behave the way they are built, and not the way they are designed, so it is imperative that the designer and reviewer engineers provide the necessary information so that the construction process is oriented towards a structure that meets all safety requirements.

In this article, we present, in a concise way, the reasons why the elongations of prestressing steels in bridges should be controlled, and in the end, we provide a comparison of a real case in contrast to what is obtained from numerical modeling. Also, you can download a spreadsheet template (Click here) for the manual calculations of the friction loss and elongations that you can use to compare with the reliable results of midas Civil.
