"Every engineer has a favorite program that they use; mine is midas FEA NX. midas FEA NX software makes complex structural modeling simple and fun. midas FEA NX has a vast array of material properties, loading types, and tools to solve, if not every, most intricate structural problem."

"midas FEA NX software was specially developed for structural engineering and has unique functions include construction stage analysis, creep, and post-tensioning. I had to consider all these effects together with a project with solid elements, and there were not many choices other than midas FEA NX software. The analysis process and results were both satisfactory and reliable. Finally, the 3D modeler is relatively easy to use and one of my favorite tools."

Construction Stage Analysis of Prestressed Concrete Girder

This webinar shows the modeling process for a prestressed concrete girder with rebars in place for detailed analysis. In this model, the rebars and tendons are modeled using curves and the girder is modeled using 3D solid. This webinar shows how to mesh reinforcement using 1D elements (embedded truss and tendon) and solid using 3D elements in Midas FEA NX. This webinar also shows how to define construction stage analysis for spliced girder by activating geometries, boundary conditions, and loads at different construction stages.  

Stimulating Contact, Concrete Cracking, And Tendon Behaviors in Internally Post-Tensioned Members Using Detailed Finite Element Method

This webinar shows different approaches to simulating contact in Midas FEA NX's 3D element models, various contact models, ways to define master surface automatically/manually. It also explains how Midas FEA NX identifies concrete cracks and calculates crack width given the concrete nonlinear behavior.   

Redundancy Analysis of Twin Steel Box Girder Bridges

Demonstrating redundancy for a dual steel box girder system involves in-depth structural analysis and may require enhancements to certain structural details. The benefit is that structures if proven redundant, can be maintained as non-fracture critical. But how to find out if your bridge is redundant or not? Daniel Mariscal will present the Redundancy Evaluation of two twin box flyover structures for the Wisconsin Department of Transportation (WisDOT). He will explain why he selected Midas FEA for this project and how to apply redundancy analysis in Midas FEA.

What is Bridge Redundancy?

Bridge redundancy is the capacity of the structure to carry loads after the structure is damaged or after one of its members ruptures. The manual for Bridge Evaluation (2008) defines bridge redundancy as the “capacity of the bridge to carry loads after damage or the failure of one or more of its members”.
