What are the limitations of current bridge researches that involves Finite Element methods and those that don't?
What are the solutions to these limitations?
Please answer clearly and provide links if needed!
Would it be better if we use like other methods like meshless, boundary element, finite volume or finite voulme method to model bridges?

Multiple methods are used. Common is "spectral element" that is like finite element, but handles spatially complex shapes well.
The major problem is that the real world is fundamentally nonlinear and finite element method is fundamentally linear. Finite elements predict fine for linear domains, but most breakdowns and component failures are now happening in nonlinear domains.
A bridge is hugely complex, and its environment varies over time, and is also complex and hard to model.
Current "hot" areas include:
- Multiphysics
- multimaterial
- nonlinear, nonhomogenous, nonisotropic
