Theory of Earthquake Recurrence Times [PDF]

open access: yes, 2006
The statistics of recurrence times in broad areas have been reported to obey universal scaling laws, both for single homogeneous regions (Corral, 2003) and when averaged over multiple regions (Bak et al.,2002).

Discrete Element Modeling of the Seismic Behavior of Masonry Construction

open access: yesBuildings, 2019
Discrete element models are a powerful tool for the analysis of masonry, given their ability to represent the discontinuous nature of these structures, and to simulate the most common deformation and failure modes.

Pseudo-Static Tests on Top Joints of Hybrid Precast Utility Tunnel

open access: yesBuildings, 2023
This paper introduces a new type of hybrid precast MUT, consisting of precast composite top slab and double-skin sidewalls with reserved rebar. The seismic behavior of the top joints was examined through pseudo-static tests.

Effective linear damping and stiffness coefficients of nonlinear systems for design spectrum based analysis [PDF]

open access: yes, 2010
A stochastic approach for obtaining reliable estimates of the peak response of nonlinear systems to excitations specified via a design seismic spectrum is proposed. This is achieved in an efficient manner without resorting to numerical integration of the

Numerical treatment of seismic accelerograms and of inelastic seismic structural responses using harmonic wavelets [PDF]

open access: yes, 2007
The harmonic wavelet transform is employed to analyze various kinds of nonstationary signals common in aseismic design. The effectiveness of the harmonic wavelets for capturing the temporal evolution of the frequency content of strong ground motions is ...
