midas Civil Enhancement 15 / 28 midas Civil 2010 Release Note Model > Boundaries > Elastic Link Analysis > Perform Analysis Stiffness of rigid type elastic link are now produced in the analysis output file (*.out). Guideline for the modeling of fixed bearing supports: An Elastic Link is frequently used for the modeling of a bearing that connects the superstructure and the substructure. To represent a movable direction and a constrained direction, the stiffness of the Link is entered as 0 or infinity. When the stiffness for infinity is not appropriate, errors can be encountered. If the stiffness is too small, it cannot represent the infinity properly. If the stiffness is too large, the analysis result can be distorted (eg, a very small horizontal reaction can be multiplied by too large stiffness in case of a curved bridge). To avoid this problem, we recommend 10e5 times the largest stiffness of the entire structure as the infinite stiffness. 10. Display Stiffness for Rigid Type Elastic Link in the Analysis Output File
