How to consider cracking in concrete using FEM

[Subject Prev][Subject Next][Thread Prev][Thread Next]

Dear Özgür
As mentioned earlier, cracked section analysis may be performed by using the reduced
moment of inertia values given in some (or most) specifications. Mainly, this calculations are necessary for deflection control, creep or shrinkage effects. But you
can use some advanced FEA softwares such as ANSYS,ADINA or LUSAS-Bridge to account for
the cracked section properties. So, you are able to perform an iterative solution and get the redistributed internal forces which is not possible in the simpified method (code method). But my thought is that this is a complicated way for you to design an
usual bridge ( if it is usual).
