How to model shrinkage effects on composite bridges??

Dear Silvia, dear all is there in Opensees a way to take into account shrinkage or thermal effects acting on composite sections?I am dealing with concrete slab on steel girders deck and i need to impose a deformation only to the slab. I suppose there is no way if a unique fibre element is used to mo...

unsymmetrical fiber section analysis

Dear Silvia, in order to understand what fiber the section axial deformation is referred to i have applied a unit moment to a unsymmetric r.c. square section with the reinforcement placed only in the upper part. The section axial deformation resulted to be different from the axial deformation of the...

Fiber section modelling of a twin girder bridge deck

Dear Silvia, i am trying to model a twin girder bridge deck section using a fiber model. Do i need to define the concrete slab and the steel beams with respect to the center of the mass (which i don't exactly know) or can i define them with respect to a arbitrary reference system?I suppose the secon...

time history analysis on a bridge pier

Hello, I am trying to do some time history analysis on a reinforced concrete bridge pier made of fiber section dispbeamcolumn elements at the base and elastic elements at the top and comparing the results with a pushover analysis. Applying at the top of the pier a force which grows in a linear manne...
