![]() ![]() Link stiffness may be modified, if necessary, to match that of the component being modeled.Internal forces are obtained for links, which is not the case for body constraints.Links are clearly shown in the model, which may assist review.A comparison of these modeling techniques is described as follows: Is there an explanation for the difference between links and body constraints?Īnswer: Application of either rigid links or body constraints is suitable for modeling a rigid connection. A combination of link objects seems to simulate the connection between girder and pier systems. What are the advantages and disadvantages between using rigid links and body constraints?Įxtended Question: I am using the Bridge Modeler to model an offset rocker bearing. ![]() ![]() What is the difference between a line constraint and an edge constraint?Īnswer: Line and edge constraint both refer to the same modeling feature except that line constraint is terminology specific to ETABS, while edge constraint is used in SAP2000. ![]()
