Because of torsion, the demanded strength and interstory drift at certain parts of the structure
increase above those required by just translational deformation. These effects differ for …

Considering that a comprehensive review of past work in this field is available, this paper
focuses on the description of two recently developed procedures to incorporate the effects of …

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 …

Observation of damage after earthquakes has shown that torsional vibration of buildings,
induced by lateral seismic ground motion, may cause serious distress in a structure …

A procedure is developed for including the effects of accidental torsion in seismic design of
buildings. It has four steps. First, the ratio between the fundamental frequencies of …

The inelastic torsional response of buildings under earthquake motions has been intensively
investigated in the past 20 years, but most of the pertinent work has been based on …

The torsional component of ground motion is a potential factor to excite the torsional
response of buildings during earthquake, which is not explicitly considered in seismic …

This paper presents evidence that the extension of conclusions based on the widely used
simplified, one story, eccentric systems of the shear‐beam type, to actual, nonsymmetric …

A simplified analysis procedure has been developed to consider accidental torsion in
building design that is rational and convenient relative to building codes. This procedure is …

It is well known that torsional oscillations during an earthquake may cause severe distress in
a building structure. Most seismic building codes therefore include some provisions for the …
