in this paper the control algorithm for controlled civil structures subjected to earthquake excitation is thoroughly investigated. the objective of this work is the control of structures by means of the pole placement algorithm, in order to improve their response against earthquake actions. successful application of the algorithm requires judicious placement of the closed-loop eigenvalues from ...

nonlinear analyses allow simulating, in a more realistic way, the behaviour of structuressubjected to several types of complex loading conditions such as earthquakes. however, it isrecognized that these analyses normally generate a considerable amount of results, a factorthat difficult its interpretation. over the last years, considerable progresses have been made instructural nonlinear behavio...

Beyond the classical dispute between architects and engineers, it is a matter of fact that art and engineering are not only compatible, but also for some cases indissociable. This communication aims to contribute to the debate. In the first part the experience of artists is exemplified in terms of influence on structural engineering : Pevsner and Snelson opened the way to complex surfaces and i...
