This paper presents a procedure for the identification of semi-rigid end connections of beam/column elements in frame structures. The technique relies on an explicit relationship between second order moments of the nodal stationary response under white noise and element end flexibilities. Such a relationship, albeit approximate, is very accurate when the element stiffness matrix is properly disassembled and can be successfully employed inside the objective function to be minimized so as to estimate the unknown parameters

Abstract
This paper presents a procedure for the identification of semi-rigid end connections of beam/column elements in frame structures. The technique relies on an explicit relationship between second order moments of the nodal stationary response under white noise and element end flexibilities. Such a relationship, albeit approximate, is very accurate when the element stiffness matrix is properly disassembled and can be successfully employed inside the objective function to be minimized so as to estimate the unknown parametersFile in questo prodotto:
