Improved equivalent viscous damping model for base-isolated structures with lead rubber bearings

Comparison of functionally-graded structures under multiple loading angles

“…16. To seek the Pareto fronts of such a MOD problem, the NSGA-II algorithm is employed to search the design space for its proven fast convergence and well-distributed Pareto front [59][60][61][62]. The Pareto fronts of À SEA α against IPF 0 1 are plotted in Fig.…”

Application and Assessment of Equivalent Linear Analysis Method for Conceptual Seismic Retrofit Design of Háros M0 Highway Bridge

“…The accuracy of the internal forces are often not sufficient, the error can be as high as 20 to 30% in some cases. Evaluating the accuracy of the ELA, several new formulations were proposed by various authors, which are based on either modifying the original equation [13,16,17,24], or creating formulae considering datasets from non-linear analyses [8,14,25].…”

“…Comparison of NLTHA and ELA has been studied and the accuracy of the ELA method has already been evaluated by several researchers: Iwan and Gates [8], Hwang and Sheng [9], Hwang [10], Hwang et al [11], Franchin et al [12], Dicleli and Buddaram [13], Jara et al [14], Simon and Vigh [15], Liu et al [16], Zordan et al [17]. However, these studies focus on the comparison of the two analysis methods and on the analysis of an equivalent single degree of freedom (SDOF) system of the example bridges, assuming regular layout (e.g.…”

Optimal Design of Tuned Mass Dampers by Performance–cost Analysis

“…In this field, many different strategies have been proposed also with regard to safety structural problems induced by random vibrations action caused by natural or artificial loads, as for example earthquakes, wind pressure, traffic vibrations, sea waves and so on [9][10][11][12][13][14][15][16]. Generally, four groups of control systems are distinguished in literature: Active, Hybrid, Semi-active and Passive.…”
