Scaling of constant‐ductility residual displacement spectrum

Earthquake Engineering and Structural Dynamics, 2020
SummaryStructures undergoing inelastic displacements during earthquake ground motions are known to sustain some amount of residual displacements, which may make those unusable or unsafe. In this study an attempt is made to estimate residual displacements for elastic‐perfectly‐plastic single‐degree‐of‐freedom oscillators with a given ductility ratio ...

Residual displacement ratios of structures under mainshock-aftershock sequences

Soil Dynamics and Earthquake Engineering, 2019
Residual displacement demand is a key indicator of seismic damage and plays a pivotal role in post-earthquake decision making on damaged structures. This parameter can be effective as an estimator of the residual capacity of structural systems damaged ...

CONSTANT-DUCTILITY RESIDUAL DISPLACEMENT RATIOS

Proceedings of the 7th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2015), 2019
This paper presents a predictive model for evaluating the central tendency and related record-to-record variability for the residual displacements of simple inelastic oscillators under seismic excitation. For this study, yielding single-degree-of-freedom systems were considered, with bilinear backbones and non-degrading hysteretic rule characterized by

A simplified reliability estimation method for pile-supported wharf on the residual displacement by earthquake

Soil Dynamics and Earthquake Engineering, 2020
Pile-supported wharves undergo lateral displacement as well as structural damage due to earthquakes. Therefore, residual displacement and structural safety assessment are necessary for earthquake-resistant design of pile-supported wharves.

Residual displacement ratios of SDOF systems subjected to ground motions recorded on soft soils

Soil Dynamics and Earthquake Engineering, 2018
120 earthquake ground motions recorded on soft soil sites were employed to assess, through response history analysis of simplified systems, the residual displacement demand, Cr, defined as the ratio of the residual displacement to the maximum elastic ...
