A hybrid model for mapping simplified seismic response via a GIS-metamodel approach [PDF]
In earthquake-prone areas, site seismic response due to lithostratigraphic sequence plays a key role in seismic hazard assessment. A hybrid model, consisting of GIS and metamodel (model of model) procedures, was introduced aimed at estimating the 1-D ...

Improved procedure for determining the ductility of buildings under seismic loads [PDF]
Displacement ductility is a parameter that characterizes the seismic response of structures. Moreover, displacement ductility can be used in order to determine whether a structural design, performed according to a specific seismic code or not, may ...

Hybrid Passive Control Strategies for Reducing the Displacements at the Base of Seismic Isolated Structures [PDF]
In this paper, the use of hybrid passive control strategies to mitigate the seismic response of a base-isolated structure is examined. The control performance of three different types of devices used for reducing base displacements of isolated buildings ...

Time-frequency representation of earthquake accelerograms and inelastic structural response records using the adaptive chirplet decomposition and empirical mode decomposition [PDF]
In this paper, the adaptive chirplet decomposition combined with the Wigner-Ville transform and the empirical mode decomposition combined with the Hilbert transform are employed to process various non-stationary signals (strong ground motions and ...

Centrifuge modeling of rocking-isolated inelastic RC bridge piers [PDF]
Experimental proof is provided of an unconventional seismic design concept, which is based on deliberately underdesigning shallow foundations to promote intense rocking oscillations and thereby to dramatically improve the seismic resilience of structures.

Numerical and experimental analysis of the leaning Tower of Pisa under earthquake [PDF]
Twenty years have passed from the most recent studies about the dynamic behavior of the leaning Tower of Pisa. Significant changes have occurred in the meantime, the most important ones concerning the soil-structure interaction.

Seismic motion in urban sites consisting of blocks in welded contact with a soft layer overlying a hard half space: I. Finite set of blocks [PDF]
We address the problem of the response to a seismic wave of an urban site consisting of $N$ non-identical, non-equispaced blocks overlying a soft layer underlain by a hard substratum.

It has long been recognized that the intensity of shaking in the epicentral region in a large earthquake is far from uniform. The common engineering approach has been to regard local site conditions as having paramount influence in the total response prediction problem.

Assessment of FEMA356 nonlinear static procedure and modal pushover analysis for seismic evaluation of buildings [PDF]
Nonlinear static analysis as an essential part of performance based design is now widely used especially at design offices because of its simplicity and ability to predict seismic demands on inelastic response of buildings.
