Dimensional response analysis of multistorey regular steel MRF subjected to pulselike earthquake ground motions [PDF]

, 2010
An alternative and efficient procedure to estimate the maximum inelastic roof displacement and the maximum inelastic interstorey drift ratio along the height of regular multi-storey steel MRF subjected to pulse-like ground motions is proposed. The method

Fuzzy-Valued Intensity Measures for Near-Fault Pulse-Like Ground Motions

Computer-Aided Civil and Infrastructure Engineering, 2013
Two fuzzy-valued (FV) structure-specific intensity measures (IMs), one based on squared spectral velocity and the other on inelastic spectral displacement, are presented to characterize near-fault pulse-like ground motions for performance-based seismic design and assessment of concrete frame structures.

Synthesis of Near-fault Ground Motion Using a Hybrid Method of Stochastic and Theoretical Green’s Functions

Frontiers in Built Environment, 2016
The effect of near-fault ground displacement is a significant factor when structures straddle a fault, because the fault produces both static step-like deformations and dynamic pulse-like ground motions. It has been observed that the static displacements

Shaking Table Test of a Base-Isolated Frame Structure under Near-Fault Ground Motions

Buildings, 2022
A five-story moment frame structural model with a base isolation system was tested on a shaking table. The isolation system comprised both linear natural rubber bearing (LNR) and nonlinear viscous dampers (NLVDs).
