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?

There are two types of studies to be done on most engineering design problems that can best be described as macro- and micro-





An overall system is usually first analyzed by a control volume approach. These approaches tend to assume uniform conditions about the structure in order to get some basic starting points. Beginning a brake design in a car by looking at kinetic energy to size the rotors, for example, is a control volume type approach.





Finite element can then take the initial and boundary conditions developed as inputs, and find any problems or opportunities that may lie in the details of structure.





So I think the answer to your questions lie in that each of the methods you identify is valid, but you have to match it to the right step in the process of the design; from overall systemic approaches to narrowed-scope, detailed analysis of critical areas.





Are you sure you don't mean "boundary condition" and "control volume" in your last paragraph describing your various methods of analysis?
