Optimum Design Method of Viscous Dampers in Building Frames Using Calibration Model

Abstract eng:
We present a new practical optimum design method of viscous dampers in building frames. In the design field of structural engineering, structural designers always try to build mathematical models to simulate the exact behavior of real world system which are often very complex for the verification analysis and are not suited for the optimum design owing to the fact that they come with a good deal of computational cost. Therefore, we present a method using calibrated response model, which is simpler than the verification model. The calibration model is a statistical prediction of the verification model and with its usage the optimum design method of dampers can be made efficient and numerically stable. The efficiency of the presented method has been demonstrated by a numerical example.
