OVERVIEW

Continuous post-tensioned bridges are very efficient structures. By eliminating the need for deck joints, this requires less maintenance, which is a significant saving in the long-term. Precast prestressed concrete (PPC) girder bridges are made continuous by using cast-in-place closure joints combined with continuous draped post-tensioning tendons.

 

The webinar will present the proper modeling of continuous post-tensioned girder bridges utilizing staged construction for the time dependency. And checking the load rating by using the resulting internal forces received from the detailed finite element analysis.

KEY POINTS

Key Point 1 : Finite Element Modeling of Post-tensioned precast girder bridge

The webinar will show a project application regarding a post-tensioned precast girder bridge. The speaker will introduce key-points of what items should be included in the finite element model along construction sequences of the bridge.

 

Key Point 2 : Refined Analysis

The another speaker will discuss on results after the analysis. We will see what results should be checked along the construction stage analysis.

 

Key Point 3 : Load Rating

We will see the load rating using AASHTO code in midas Civil. The speaker will show the whole procedure to check the load rating with key-points.
