Estimating Arias Intensity From Response Spectrum
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Arias intensity serves as a crucial metric to measure ground motion energy and is extensively utilized in earthquake engineering to analyze structural damage, slope instability, and the potential for soil liquefaction. Nevertheless, in many practical design scenarios, only the response spectrum is available, without corresponding information ...

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT To enhance the structural robustness of bridges, a rocking arch‐shaped segmental pier with a double sliding system was previously proposed as a low‐cost solution to protect bridges in developing countries. The rocking behavior is triggered by halting the sliding motion, which increases the horizontal load‐bearing capacity and limits ...

Development and application of the phase-screen seismic modelling code [PDF]
, 2009 As a consequence of the aims of this project, this thesis is divided into two distinct sections. Initially, the computationally efficient phase-screen forward modelling technique is extended to allow investigation of non-normal ray paths.

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT This paper illustrates opportunities for the use of simulated ground motions in seismic performance assessment – from seismic hazard, ground‐motion selection, response history analysis, and seismic demand hazard calculation. The illustration is through a comparative analysis with the conventional alternative of observed ground motions.
