The problem of earthquake induced torsion in buildings is quite old and although it has
received a lot of attention in the past several decades, it is still open. This is evident not only …

Historically, the seismic performance of structures with conditions of structural irregularity
has been poor in strong earthquakes when compared to those of regular structures. In …

In view of the stronger vulnerability of horizontally irregular structures during earthquakes,
numerous studies have been made since mid-1950 s. Unfortunately, research progress in …

The paper deals with the seismic retrofit of a multiple building structure belonging to the
Hospital Centre of Avellino (Italy). At first, the paper presents the preliminary investigations …

One of the established conditions of structural regularity in modern Mexican seismic codes is
that a rigid and strong diaphragm has to be provided at each story. However, this condition …

A study devoted to define the diaphragm condition using linear-elastic analyses for
structures with the most widely used floor systems in Mexico (two-way ribbed RC slabs …

ABSTRACT A procedure is presented for performing Eurocode 8-compliant spectral
analyses of reinforced concrete structures by means of seismic response envelopes. To …

The most important recent earthquakes showed the importance of seismic behavior of
various types of structures such as infilled frames: Japan 2011 (Takewaki et al., 2011), Haiti …

While plan-asymmetric structures have more potential for torsional effects and diaphragm
flexibility during seismic response, they had received less attention from this viewpoint in …

The present study aims to address the effect of soil− structure interaction (SSI) on the
seismic performance of an urban building with a steel frame (hinge/shear connection) and …
