Investigating the seismic response of ancient multi-drum colonnades with two rows of columns using an object-oriented designed software
(2012)
A software application, based on the Discrete Element Method (DEM), has been developed, using a modern object-oriented design and programming approach, in order to enable the effective simulation of multi-drum columns and ...
Effect of the seismic excitation angle on the dynamic response of adjacent buildings during pounding
(2015)
The excitation angle or angle of incidence is the angle in which the horizontal seismic components are applied with respect to the principal structural axes during a time history analysis. In this study, numerical simulations ...
On poundings of a seismically isolated building with adjacent structures during strong earthquakes
(2010)
This paper presents selected indicative results from an extensive parametric investigation that has been performed in order to assess the effects of potential earthquake-induced poundings on the overall dynamic response ...
A nonlinear impact model for simulating the use of rubber shock absorbers for mitigating the effects of structural pounding during earthquakes
(2013)
SUMMARY During strong earthquakes, structural poundings may occur between adjacent buildings because of the limited separation distance and the deformations of their stories. A potential mitigation measure for this problem ...
Assessing the effect of inherent nonlinearities in the analysis and design of a low-rise base isolated steel building
(2013)
Seismic isolation is an effective method for the protection of buildings and their contents during strong earthquakes. This research work aims to assess the appropriateness of the linear and nonlinear models that can be ...
An efficient methodology for simulating earthquake-induced 3D pounding of buildings
(2014)
The current paper presents an efficient methodology for numerically simulating in three dimensions adjacent buildings that may experience pounding during strong earthquakes. In particular, a new approach to the numerical ...
Monitoring Social Networks Formation and Information Velocity for Cases of Airliners' Crashes
(2015)
Airliners' industry corresponds to an extremely sensitive and volatile sector, especially subject to information related to flights safety. Possible negative publicity on such issues may result to sudden and abrupt ...
Waterloss Detection in Water Distribution Networks using Wavelet Change-Point Detection
(2017)
The work presented herein addresses the automatic detection of water losses in water distribution networks (WDN), through the dynamic analysis of the time series related to water consumption within the network and the use ...
Vulnerability of Urban Water Distribution Networks under Intermittent Water Supply Operations
(2016)
The work presented herein investigates the effects of intermittent water supply (IWS) on the condition and breakage rate of urban water distribution piping networks (WDN), by studying the change in the rate of occurrence ...
Two-dimensional numerical investigation of the effects of multiple sequential earthquake excitations on ancient multidrum columns
(2016)
Ancient monuments of Greek and Roman classical architecture usually consist of multi-drum columns that are constructed of stone blocks placed on top of each other. Several research studies deal with the seismic behaviour ...
