DIN-2015-0038 - REDUCED-ORDER MODEL FOR PARAMETRIC EXCITATION OF A SUBMERGED, VERTICAL AND FLEXIBLE CYLINDER: A CALIBRATION APPROACH STUDY

Abstract: In the literature, there are several works devoted to the development of models of planar frame structures that take into account the different non-linear behavior inherent to these structures. In addition, the research of the methodology to solving the problems resulting from these properties is abundant. The aim of the present work is to start a restructuring project for a coding language which is more simple, compact and with excellent features of the graphic display of some procedures structured in Fortran and used to develop the computer system CS-ASA, project which has been developed for over 15 years by a group of researchers in Structural Engineering. In the present paper, we present a code in Matlab with the procedures required to perform the static analysis of the structural models composed of finite elements of the beam-column which has geometric nonlinearity.
Keywords: reduced-order model; parametric excitation; experiments; calibration

The aim of the present work is to start a restructuring project for a coding language which is more simple, compact and with excellent features of the graphic display of some procedures structured in Fortran and used to develop the computer system CS-ASA, project which has been developed for over 15 years by a group of researchers in Structural Engineering. In the present paper, we present a code in Matlab with the procedures required to perform the static analysis of the structural models composed of finite elements of the beam-column which has geometric nonlinearity.

Abstract: In the literature, there are several works devoted to the development of models of planar frame structures that take into account the different non-linear behavior inherent to these structures. In addition, the research of the methodology to solving the problems resulting from these properties is abundant. The aim of the present work is to start a restructuring project for a coding language which is more simple, compact and with excellent features of the graphic display of some procedures structured in Fortran and used to develop the computer system CS-ASA, project which has been developed for over 15 years by a group of researchers in Structural Engineering. In the present paper, we present a code in Matlab with the procedures required to perform the static analysis of the structural models composed of finite elements of the beam-column which has geometric nonlinearity.
