Dynamic Reliability Analysis of Large-Span Structures under Crowd Bouncing Excitation

Stochastic 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...

Reliability Analysis of Structures with Interval Uncertainties under Stochastic Excitations

In this paper, an approach able to evaluate approximate explicit expressions of interval response statistics and structural reliability of randomly excited linear structures with uncertain parameters is addressed. The excitation is modeled as a stationary Gaussian random process. Uncertainty in structural parameters is handled by applying the interval model. Under the assumption of independent ...

Dynamic Reliability Assessment of Long-span Suspension bridges under stochastic traffic flow

For most existing bridges, supporting continuous traffic loads is the basic function. However, in addition to this load, bridges are exposed to environmental (Frangopol and Soliman, 2015 [1]), as well as various other complex loads, that are mostly random in nature, such as earthquake, flow-included loadings, wind and so on. All these loading conditions need to be considered and must satisfy th...

Dynamic Analysis of Asymmetric Structures Supported by a Sliding Foundation

analysis on response of dynamic systems to pulse sequences excitation

near-fault ground motions with long-period pulses can place severe demands on structures near an active fault. these pulse-type ground motions can be represented by pulse sequences with simple shapes. half-sinusoidal pulse sequences are used to approximate recorded ground motions and dynamic responses of sdof system under the excitation of these pulse sequences are studied. four cases are consi...
