Control of Structural Response Under Earthquake Excitation
This study firstly proposes some representative simple methods to obtain the suboptimal passive damping and stiffness parameters from the optimal control gain matrix since it is not possible to add the exact optimal damping and stiffness parameters to the structure in practice. It is shown numerically that modifying the structural damping and the stiffness in the proposed suboptimal ways may su...
متن کاملEstimating earthquake-induced failure probability and downtime of critical facilities.
Fault trees have long been used to estimate failure risk in earthquakes, especially for nuclear power plants (NPPs). One interesting application is that one can assess and manage the probability that two facilities - a primary and backup - would be simultaneously rendered inoperative in a single earthquake. Another is that one can calculate the probabilistic time required to restore a facility ...
متن کاملAn Enhanced HL-RF Method for the Computation of Structural Failure Probability Based On Relaxed Approach
The computation of structural failure probability is vital importance in the reliability analysis and may be carried out on the basis of the first-order reliability method using various mathematical iterative approaches such as Hasofer-Lind and Rackwitz-Fiessler (HL-RF). This method may not converge in complicated problems and nonlinear limit state functions, which usually shows itself in the f...
متن کاملStochastic analysis of two adjacent structures subjected to structural pounding under earthquake excitation
Seismic pounding occurs as a result of lateral vibration and insufficient separation distance between two adjacent structures during earthquake excitation. This research aims to evaluate the stochastic behavior of adjacent structures with equal heights under earthquake-induced pounding. For this purpose, many stochastic analyses through comprehensive numerical simulations are carried out. About...
متن کاملProbability of Detecting an Earthquake
We present a new method for estimating earthquake detection probabilities that avoids assumptions about earthquake occurrence, for example, the event-size distribution, and uses only empirical data: phase data, station information, and network-specific attenuation relations. First, we determine the detection probability for each station as a function of magnitude and hypocentral distance, using...
