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 …

Rigorous assessment of structural response to seismic excitation poses challenges for
researchers in their bid to account for the effects of (1) biaxial interaction; and (2) incidence …

New developments in the response spectrum method have led to calculations in seismic
stresses that are more accurate, and usually lower, than those obtained by conventional …

The modal pushover analysis (MPA) procedure, presently restricted to one horizontal
component of ground motion, is extended to three‐dimensional analysis of buildings …

A response spectrum method for dynamic analysis of linear structures subjected to
multicomponent seismic input is developed. The method is based on elementary concepts of …

A response spectrum rule for combining the contributions from three orthogonal components
of ground motion to the maximum value of a response quantity is presented. This rule …

This paper aims to develop an improved understanding of the critical response of structures
to multicomponent seismic motion characterized by three uncorrelated components that are …

Resistant Concrete Structures (1997). We are grateful for his consent to reproduce a number …

The existing rules for combining peak response to individual components of ground motion
are evaluated. The response values re to two horizontal components of ground motion …

Highway bridges in seismic zones are commonly designed with oblong columns, featuring
different force-displacement relationships and seismic capacities along different response …
