📌 Description

Rail-Structure Interaction (RSI) is becoming increasingly important for railway bridge projects that require more realistic evaluation of track–structure behavior, especially where turnout zones, bridge expansion joints, and transition sections overlap within limited distances. In these cases, engineers need a more detailed review of rail-level displacement and structural response beyond simplified RSI assumptions.

In the SEA market, especially in Malaysia and Vietnam, this topic is becoming increasingly relevant for engineers involved in railway bridge design, review, and project delivery. As railway infrastructure projects continue to expand, practical RSI workflows that can be applied directly in engineering work are becoming more valuable.

In this webinar, we will first share a railway bridge case presentation based on Rail-Structure Interaction of High-Speed Railway Bridges and Design Case Study of Rahmen-Type Bridge using Civil NX. The session will cover why special RSI analysis is required, how detailed turnout modeling and rail-level modeling can be used, how relative rail–structure displacement is evaluated, and how these findings connect to structural reinforcement and design decisions.

Following that, Jayakrishnan (JK) will continue with a practical MIDAS session to explain how these RSI workflows can be approached in CIVIL NX from a user and engineering application perspective. Through the full session, participants will gain a clearer understanding of how RSI-related analysis and review can be applied more effectively in real railway bridge projects.
