A simplified approach of assessing torsionally balanced (TB) and torsionally unbalanced
(TU) low-medium rise buildings of up to 30 m in height is presented in this paper for regions …

The paper introduces simplified methods for the analysis of multi-storey buildings for regions
of low to moderate seismicity. Due to functional and architectural requirement most newly …

The cost of providing an effective earthquake-resistant design for buildings in an area
subject to seismic activity depends mainly on the characteristics of the earthquakes in the …

Plan-wise irregular buildings are quite common in many earthquake-prone areas of Europe
and worldwide, making up a remarkably important category of existing structures. Irregular …

This paper evaluates the applicability of the static method for the seismic design of
torsionally unbalanced buildings. In evaluating this method it is deemed that the design of a …

A modified procedure is presented for assessing the seismic response of elastic non-
proportionate multistory buildings. This procedure retains the simplicity of the methodology …

Seismic building codes include design provisions to account for the torsional effects arising
in torsionally unbalanced (asymmetric) buildings. These provisions are based on two …

With the aid of perturbation analysis of vibration frequencies and mode shapes it is shown
that any lower vibration mode of a torsionally coupled building may be approximated as a …

The paper investigates the influence of design procedures on the seismic response of multi-
storey asymmetric buildings. To this end, some structures are designed according to …

The elastic response of torsionally-coupled, one-story framed buildings to earthquake
ground motion is presented for a wide range of values of the various system parameters …
