See how MIDAS CIVIL NX simulates the erection sequence of a 200 m steel arch–composite bridge and evaluates its behaviour from construction to final design.
The structural behaviour of a long-span steel arch bridge changes continuously as the arch, girders, bracing and concrete deck are progressively erected and connected. Each construction stage can influence the forces, deformations and stability of the structure.
In this live technical session, we will demonstrate how MIDAS CIVIL NX can be used to simulate the erection sequence of a 200 m steel arch–composite bridge, including staged activation of structural components, temporary supports and construction loads.
The session will also show how to establish composite action through deck casting, section-property changes and load transfer between the steel girders and concrete deck.
Stage-wise results including displacement, arch thrust, member forces, stresses and stability will be reviewed, followed by verification of the completed bridge under applicable design load combinations.
One continuous analysis — from erection sequence to final bridge design.
