A long-stroke semi-active MR damper for building control using tuned masses
(National Information Centre of Earthquake Engineering, 2017)
In this research the comprehensive development of a long-stroke MR-damper designed to control the earthquake performance of an existing 21-story reinforced concrete building in Santiago (Chile) by reacting on one of its ...
Floor Response of SDOF Systems with Metallic Structural Fuses
(2004-06-26)
The floor demands of Single-Degree-of-Freedom (SDOF) systems designed or retrofitted with metallic structural fuses are studied in this article. Floor velocity and acceleration are obtained and comparisons are made between ...
Seismic Design of Multi-story Buildings with Metallic Structural Fuses
(2006-06-28)
Seismic design relies on inelastic deformations through hysteretic behavior. However, this translates into damage on structural elements, permanent system deformations following an earthquake, and possibly high cost for ...
Seismic Response of Hybrid Systems with Metallic and Viscous Dampers
(2016-06-27)
Metallic dampers can enhance structural performance by reducing seismically induced lateral displacements, and by reducing inelastic behavior of beams and columns. Limiting story drift also indirectly allows for mitigation ...
Experimental and numerical analysis to collapse of a framed structure subjected to seismic loading
(Elsevier, 2015-01)
The nonlinear numerical analysis to collapse of civil structures presents several difficulties, even for mechanically well-characterized materials, such as steel. In the case of steel, where the nonlinear constitutive ...
Time-variant modal parameters and response behavior of a base-isolated building tested on a shake table
(Earthquake Engineering Research Institute, 2018)
This paper presents the identification of the instantaneous modal properties
and the experimental response of a full-scale, five-story base-isolated RC building tested on a shake table. A suite of earthquake motions of ...
Physical modelling of liquefiable soils in shaking table
(UniandesMaestría en Ingeniería CivilFacultad de IngenieríaDepartamento de Ingeniería Civil y Ambiental, 2016)
The dynamic models are widely used to estimate the soil behaviour during earthquakes. These models are useful to validate numerical data or to understand failure mechanisms induced in that kind of events. During the quake ...

Strains on steel reinforcement of low-rise concrete walls during shake table tests
(Universidad Nacional de Colombia - Facultad de Ingeniería, 2014-04-25)
During the last few decades, several advantages of concrete wall housing have been identified when compared with masonry houses located in high hazard seismic zones; for instance, higher lateral stiffness and strength, and ...
