Integral Abutment Bridge Design with Soil Structure Interaction

Intergral Autment Bridge Design with Soil Structure Interaction

Purpose of the Webinar
This session would cover an excellent example for multi-span extradosed bridge. The discussion would cover topics like construction methodology adopted to reduce the construction duration and economizes the overall cost as well as, construction constraints such as tidal conditions and weather. Also, a brief on how bridge progress till date substantiates the importance of sound efforts in planning, design, and management.

Purpose of the Webinar
Suthichai of HDR will share his experience on the fruit street bridge replacement project using midas Civil. He will demonstrate some technical remarks regarding MassDOT's design criteria for Integral Abutment bridges (IAB). Furthermore, he will demonstrate how he utilized midas Civil for review the entire structure behavior and design results including the soil structure interaction effects. His demonstration will focus on (1) how to set up, analyze and design the entire structure model, (2) how to apply complex soil spring data automatically, and (3) how to get Wood Armer moments for the shell-modeled abutment wall design.

 

Project Highlights
Replacement of the concrete Tee/I girder bridge to steel plate I girder integral abutment bridge
- Why Integral Abutment Bridge (IAB) is MassDOT's #1 choice
MASSDOT's design criteria
- MassDOT IAB design & analysis
- IAB Load, load factor and load combination
- IAB pile, wingwall, and abutment design
