Because of the difference between the actual and computed eccentricity of buildings,
symmetrical buildings will be affected by torsion. In provisions, accidental eccentricity is …

The general trends of inelastic behaviour of plan-asymmetric structures have been studied,
without any restrictions imposed by particular code requirements for torsion. Systems with …

Building codes recognize a variety of sources of accidental eccentricity in buildings
subjected to seismic excitation. This study examines the adequacy of code provisions for …

Presently, the researches of displacement-based seismic design almost belong to two
dimensions analysis. Both theoretical researches and seismic disasters indicate that the …

Due to the lack of access to the data of three rotational components of earthquakes, Seismic
analysis of new buildings as well as assessment of the vulnerability of existing structures are …

This paper evaluates the inelastic seismic response of torsionally unbalanced structural
systems with strength distributed using elastic response spectrum analysis. The structural …

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 work studies a new design procedure to account for accidental torsion in buildings
subjected to seismic ground motions. The procedure does not require a design accidental …

Earthquake investigations confirm that un-symmetric buildings suffer more damage than
their symmetric counterparts. Torsional vibrations due to irregularity are one of the main …

Irregular structures present a particular design challenge for structural engineers, especially
if they are located in seismically active areas. It has been observed that in earthquake …
