Nonlinear seismic analysis of irregular rc framed buildings base-isolated with friction pendulum system under near-fault excitations

F Mazza, M Mazza - Soil Dynamics and Earthquake Engineering, 2016 - Elsevier
The application of the friction pendulum (FP) system is increasing due to its conceptual
simplicity; yet there are still aspects of its behaviour that need further attention. Long duration …

Collapse probability of code-based design of a seismically isolated reinforced concrete building

N Güneş, ZÇ Ulucan - Structures, 2021 - Elsevier

Lateral-torsional response of base-isolated buildings with curved surface sliding system subjected to near-fault earthquakes

F Mazza - Mechanical Systems and Signal Processing, 2017 - Elsevier
The curved surface sliding (CSS) system is one of the most in-demand techniques for the
seismic isolation of buildings; yet there are still important aspects of its behaviour that need …

Accidental eccentricity in multistory buildings due to torsional ground motion

D Basu, S Giri - Bulletin of Earthquake Engineering, 2015 - Springer
Accidental eccentricity is aimed to account for any unforeseen factor that may attribute to the
torsional response. These sources can be broadly classified into two components, namely …

Evaluation of seismic torsional response of ductile RC buildings with soft first story

CHBV Hareen, SC Mohan - Structures, 2021 - Elsevier
