Determining the Optimal Scalar Intensity Measure of Floor Communication Towers

Shock and Vibration, 2022
Various structural types and ground motion characteristics lead to distinct intensity measures of structural seismic performance. For the lattice high-rise steel structure of communication towers, determining the intensity measures to adjust ground ...

Dimensional response analysis of bilinear systems subjected to non-pulselike earthquake ground motions [PDF]

, 2011
The maximum inelastic response of bilinear single-degree-of-freedom systems when subjected to ground motions without distinguishable pulses is revisited with dimensional analysis by identifying time scales and length scales in the time histories of ...

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

DESIGN RESPONSE SPECTRA FOR PULSE-LIKE GROUND MOTIONS

Journal of Structural and Construction Engineering (Transactions of AIJ), 2010
In recent inland shallow earthquakes, pulse-like ground motions have been observed which subsequently caused severe damage to buildings. However, the response of buildings to pulse-like ground motions has not been sufficiently characterized yet. In this study, we investigate the effect of pulse-like ground motions on the design of structures and define

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).

Energy-based response prediction of reinforced concrete buildings with steel damper columns under pulse-like ground motions

Frontiers in Built Environment, 2023
The response of structures under pulse-like ground motions is characterized by the large amount of energy input in a few cycles. Consequently, structures with insufficient strength may suffer severe damage owing to excessive deformation.

Effects of pulse-like ground motions and wavelet asymmetry on responses of cantilever retaining wall

, 2023
Fault-rupture processes produce pulse-like ground motions in near-fault regions. These motions are characterized as large-amplitude long-period pulsing that can cause severe structural damage.

The effect of directivity-induced pulse-like ground motions on fracture risk of welded steel column splices [PDF]

, 2019
Recent, worldwide earthquakes have highlighted the destructive potential of near-fault, pulse-like ground motions caused by forward directivity. This study investigates the fracture risk of welded steel column splices (WCSs) in near-fault regions ...
