The seismic ductility spectra (SDS) method is a crucial tool to quickly evaluate the ductility
demand of bridge columns with varied constitutive models. However, conventional SDS …

Advanced seismic isolation devices and systems have been recognized as promising
measures toward resilient design of bridge structures. This paper proposes a base isolation …

Unbonded prestressed reinforced concrete (UBPRC) column has attracted the attention of
many researchers in bridge seismic design because of its small residual displacement …

ABSTRACT A novel model is constructed to investigate the coupling effect of pulse period
(Tp) and peak pulse velocity (Vp) on structural demands with the varied fundamental period …

This study presents the derivation of closed-form component limit state expressions for high-
strength concrete columns reinforced with high-strength steel bars (HSC-HSSB) from an …

Abstract The Shape Memory Alloy (SMA)-restrained bearing consists of a typical sliding
bearing and SMA wires. The SMA wires are adopted to limit the excessive displacement …

Structures designed with high ductility often have significant residual displacement. As a self-
centered structure, unbonded prestressed reinforced concrete (UBPRC) columns can …

The acquisition of a flexural backbone curve for columns primarily relies on finite element
analysis and experiments, of which the complexity and high cost are significant challenges …

The seismic resonance behavior of soil-pile-structure systems (SPSS) with scour effects is a
complex problem due to the interaction of soil, pile foundation, and structure. This study …

Earthquake and flood scour are two main causes of failures to highway bridges. This study
developed an alternative fragility analysis framework of bridges based on endurance time …
