How can it can be modeled, what type of link support type to be used for it, what will be its mass, weight, effective stiffness, what will be the six degrees of freedom? Thanks in advance...
Model thems as two point link support, fix only translational degrees of freedom. If u want a roller joint in any direction release u1 or u2 as the case may be. For stiffneess, G is the parametr, can be taken from AASHTO in relation to the duron thickness, normally 65 duron is the common choice for bridges
