Seismic Response of Building Structures with Sliding Non-structural Elements

Interaction between a structure under base excitation and heavy non-structural elements that it supports is significant in the seismic analysis and design of the structure. Heavy non-structural elements may slide/rock under base excitation, and this dynamic action affects the seismic behavior of the supporting structure. Hence, in this study, a numerical model was presented to describe the seis...

Seismic Mitigation of Building Frames using Magnetorheological Damper (TECHNICAL NOTE)

The present study focusses on the damping force control of shear mode magnetorheological (MR) damper for seismic mitigations. Therefore, the semi-active MR damper which can control the vibration is analyzed both experimentally and numerically. Carbonyl iron is used as the magnetic particle and Castrol Magnetec oil as carrier fluid throughout the study. MR damper is designed and fabricated, and ...

The Effect of Tuned Mass Damper on Seismic Response of Building Frames with Uncertain Structural Characteristics

Tuned mass dampers (TMDs) could be used to absorb the input energy of the applied load, and reduce the response of the building frames. However, the effectiveness of TMD in reducing the response of the building frames could be affected by inherited uncertainties in the structural characteristics of the frames. In this study, in order to investigate the probabilistic response of steel moment-res...

Seismic Mitigation of a Historic Masonry Building

This work presents an analysis of different proposals of rehabilitation of a masonry building, built around the beginning of the XX century for public schools, in the highest seismic risk zone of Argentine; and which was closed down after Mendoza`s Earthquake in 1985. The building has masonry walls of artisanal ceramic bricks and wood-framed roof but it does not have lateral ties. Currently, it...
