OPTIMAL CONSTRAINED DESIGN OF STEEL STRUCTURES BY DIFFERENTIAL EVOLUTIONARY ALGORITHMS
Structural optimization, when approached by conventional (gradient based) minimization algorithms presents several difficulties, mainly related to computational aspects for the huge number of nonlinear analyses required, that regard both Objective Functions (OFs) and Constraints. Moreover, from the early '80s to today's, Evolutionary Algorithms have been successfully developed and applied as a ...
متن کاملActive Control of Structures
In recent years a large large amount of work on the active control of the flexible structures has been done. The concrete engineering problems that motivate this study come from very different fields: aerospace, structures, meteorology, nanotechnology, etc. An overview can be found in the book of Fuller, Elliot and Nelson [5]. The problem of active vibration control (AVC) can be set in the fram...
متن کاملnon-linear study of various slit shear walls in steel structures
seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
15 صفحه اولActive Control in Structures
In this paper the application of control theory to structural engineering has been presented from a structural engineering perspective. The objective of this paper is to summarize key steps that are required to design an active control system for a structure. Total acceleration feedback with H2/LQG controller is used in this paper. The structural control device is made of tendon/pulley system. ...
متن کاملRandomized digital optimal control
In sampled data systems the sampling periods are almost always assumed to be deterministic, i.e., known in advance. However, in practice, the sampling periods should often be conceived as stochastic variables. This so called stochastic sampling phenomena occurs in many areas of sampled data systems such as in biological control systems or when a human being selects the sampling instants. Data m...
