Abstract
In this study, several peak and energy vector-valued ground motion intensity measures (IMs) are proposed to predict maximum inter-story drift and hysteretic energy demands of 3D reinforced concrete (R/C) buildings subjected to narrow-band motions. The selected vector-valued IMs are based on the spectral acceleration, pseudo-velocity, velocity and input energy at first mode of the structure as first component. As the second component, ground motion parameters based on peak, integral and spectral shape proxies such as the well-known Np are used. The objective of the present study is to provide vector-valued IMs whit the ability to predict the maximum inter-story drift and hysteretic energy demands on 3D framed structures. It is observed that vector-valued IMs based on Np provide a high relation whit maximum inter-story drift and hysteretic energy demands of reinforced concrete framed buildings.
