The paper presents an overview of the progress in research regarding seismic response of
plan and vertically irregular building structures. Three areas of research are surveyed. The …

Torsional status indicators of asymmetrical plan systems are evaluated. The ratio of two
modal participation factors in a translational direction (lower to higher mode) is proved as a …

The paper presents a study on the seismic behavior of irregular unreinforced masonry
buildings, aiming at evaluating the effects of higher modes. First, the macroelement model …

Abstract The Asinelli Tower, built at the end of the 12th century, is one of the main symbol of
the town of Bologna and a valuable historical heritage of the Medieval age of the entire Italy …

Due to earthquakes, many structures suffered extensive damages that were attributed to the
torsional effect caused by mass, stiffness or strength eccentricity. Due to this type of …

The assessment of maximum displacement demand is a crucial point in the design of
seismic isolating systems, in particular when the non linear behaviour of devices is modeled …

The paper deals with the applicability of the extended N2 method to base‐isolated plan‐
asymmetric building structures. The results obtained by the usual pushover analysis of a 3D …

This paper gives a new insight into the linear dynamic behavior of one-storey eccentric
systems, with particular attention devoted to provide a comprehensive physically-based …

Recent developments in performance-based seismic design and assessment approaches
have emphasized the importance of properly assessing and limiting the residual …

The coupled lateral-torsional response is observed in building structures subjected to
dynamic excitation due to lack of symmetry in terms of mass/stiffness in any of the stories' …
