<p>The paper introduces a novel approach for modeling nonlinear hysteretic behavior of reinforced concrete structures in the complex frequency domain. The new approach can be used to perform fast and accurate nonlinear SSI analyses, including sophisticated ...

This paper examines the consistency of seismicity and ground motion models, used for seismic hazard analysis in New Zealand, with the observations in the Canterbury earthquakes. An overview is first given of seismicity and ground motion modelling as inputs ...

This paper provides a comparison between the strong ground motions observed in the Christchurch central business district in the 4 September 2010 Mw7.1 Darfield, and 22 February 2011 Mw6.3 Christchurch earthquakes with those observed in Tokyo during the 11 ...

Rotational and vertical components of ground motion are almost always ignored in design or in the assessment of structures despite the fact that vertical motion can be twice as much as the horizontal motion and may exceed 2g level, and rotational excitation ...

A set of approximate, multivariable relations is established to evaluate soil effects on the peak horizontal acceleration, the peak horizontal velocity and the horizontal elastic response spectra (5% damping). The basic innovation of the approach is the use ...

Characteristics of vertical and horizontal component strong ground motions have been examined to reveal general trends which may be of significance to structural analyses. Recordings at both rock and deep soil sites representative of WUS showed distinctly ...
