Abstract: A finite-element displacement formulation and solution procedure are developed for the analysis of large displacement problems of viscoelastic beams and frames. The displacements considered are of ...

Abstract: A procedure for the design of controllers for tall buildings under wind loads is presented. It is assumed that there are constraints on the design, in terms of requiring that the root-mean square (RMS) values of certain ...

Abstract: A buckling restrained knee braced truss moment frame (BRKBTMF) is a novel steel structural system that combines steel trusses with buckling-restrained braces (BRBs) to form an alternative seismic force–resisting system. ...

Abstract: The concept of using neural networks to predict future values of constrained performance variables as part of an adaptive structural controller is proposed. Neural networks are first trained using simulated responses and ...

Abstract: A sampled data control algorithm taking into account external excitations was developed for structural engineering applications. The structure was modeled as a continuous system controlled by a digital control system. In ...

Abstract: This paper presents a method, which uses techniques from adaptive control, to identify a simplified model of a complex structure using measurements of the input excitation and forces and the output displacements of the ...

Abstract: A closed-loop complete-feedback control algorithm is proposed for the control of a building modeled as a single-degree-of-freedom (SDOF) system using an active tuned mass damper (ATMD). The control force is calculated from ...

Abstract: A control methodology is presented for a column, modeled as a single-degree-of-freedom system subjected to simultaneous horizontal and vertical support motion. It is assumed that the support motions are uncertain, time ...

Abstract: This paper proposes a combined feedback–feedforward control algorithm for reducing structural response of buildings to seismic excitations. The controller contains both feedback and feedforward components. The feedback ...

Abstract: A stochastic finite element method is developed for reliability studies of problems such as beam‐columns under axial loading with random geometric imperfections, uncertain material properties, and uncertain moduli of elastic ...
