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 …

The seismic design of buildings and other structures should include provisions for inherent
and accidental torsion effects. Procedures developed decades ago for use with equivalent …

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 …

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 …

The reinforced concrete (RC) frame-shear wall structure is a typical structural system for
modern high-rise buildings. This paper investigates the influence of vertical setback on its …

The buildings with the presence of setback irregularity are now being increasingly used in
the urban areas. The present work proposes an irregularity index for quantifying the setback …

Static torsional provisions employing equivalent lateral force method (ELF) require that the
earthquake-induced lateral force at each story be applied at a distance equal to design …

Shear strength of reinforced concrete (RC) beam-column joint depends on several
parameters including the strut width, which in turn is a function of the compression depth in …

Setback structures, characterized by their irregular geometric shape and height setbacks,
introduce vulnerabilities into the structural system. These vulnerabilities hold significant …

Setback is a building regulation enforced to regulate spacing between two buildings in order
to have adequate solar exposer and ventilation. It is mandatory on the part of every …
