it is well-known that the behavior of soil-structure systems can be well described using a limited number of non-dimensional parameters. this is the outcome of researches based on the premise that the foundation is bonded to the ground. here, it is shown the concept can be extended to systems with foundation uplift. a set of non-dimensional parameters are introduced which controls the main feat...

abstract for seismic design, it is important to estimate the, maximum lateral displacement (inelastic displacement) of the structures due to earthquakes for several reasons. seismic design provisions estimate the maximum roof and storey drifts occurring in major earthquakes by amplifying the roof displacement and drifts of the structures obtained by elastic analysis subjected to seismic design ...

this study is investigated the optimum parameters for a tuned mass damper (tmd) under the seismic excitation. shuffled complex evolution (sce) is a meta-heuristic optimization method which is used to find the optimum damping and tuning frequency ratio for a tmd. the efficiency of the tmd is evaluated by decreasing the structural displacement dynamic magnification factor (ddmf) and acceleration ...

Effect of V2 Accent on relationships (a) between duration and displacement/velocity ratio, and (b) between peak velocity and displacement for /i/-to-/a/ tongue lowering gestures in the y dimension.. Figure 6.6. Effect of V2 Accent on relationships (a) between duration and displacement/velocity ratio, and (b) between peak velocity and displacement for /a/-to-/i/ tongue fronting gestures in the x...

The proportion of excess deaths occurring as a result of hot weather that are brought forward by only a short time ("displaced") is important but not easy to estimate. A recent proposal by Saha et al. (Am J Epidemiol. 2014;179(4):467-474) was to estimate this using a "displacement ratio" equal to the sum of deficits of daily deaths below an expected baseline divided by the sum of excesses over ...
