Shake table tests on nonlinear steel fuses for the acceleration-control of nonstructural components Open
During recent major earthquakes, modern seismically designed buildings have demonstrated a low risk of collapse and life-safety limit states. However, both direct and indirect economic losses are often primarily due to damage to nonstructu…

A novel bidirectional friction damper for retrofitting of RC precast structures: Experimental and numerical assessment Open
Precast RC structures, commonly used since the '60 s for industrial and commercial buildings, often feature poor connections among the main structural elements and between structural and non-structural components due to sub-standard old bu…

Effect of cyclic thermal loading on the behaviour of integral abutment bridges: a large-scale experimental study in a soil pit Open
We investigate abutment–backfill interaction in integral bridges (IBs) under thermal loading over a large number of cycles for a 120-year life span as specified by modern design codes. To better understand the associated mechanisms and ass…

Methodology for Reliability Analysis of Reinforced Concrete Structures over time Considering Combined Corrosion Open
One of the main causes of deterioration in reinforced concrete structures (RC) is the corrosion of steel bars. Many factors, including materials, environments, and loading conditions, which often have uncertain characteristics, affect the …

Incorporating soil‐structure interaction into simplified numerical models for fragility analysis of RC structures Open
Simplified building models are a valuable option for seismic assessment at the regional scale. These models often use calibrated springs to model column behaviour, and recent advances have made them suitable for capturing torsional respons…

SSI‐induced seismic earth pressures on an integral abutment bridge model: Experimental measurements versus numerical simulations and code provisions Open
Integral abutment bridges (IABs) generate strong soil–structure interaction (SSI) effects due to their high structural stiffness and transmission of inertial and thermal loads generated at the deck directly to the abutments. Despite an inc…
View article: Sufficiency assessment of intensity measures for natural and spectral-matched ground motion records
Sufficiency assessment of intensity measures for natural and spectral-matched ground motion records Open
A correct Intensity Measure (IM) selection is essential for Performance-Based Earthquake Engineering (PBEE) applications, as any probabilistic seismic demand model (PSDM) depends significantly on the IM. If a single IM can describe the com…

Functionality assessment of road network combining flood roadworthiness and graph topology Open
Flood hazards can affect road networks by closing roads, extending travel distances and lengthening travel times. This paper innovatively integrates flood hazard, road network topology and vehicle vulnerability via a severity factor to ass…
View article: Low-cycle fatigue behaviour and strain-life model of stainless steel reinforcing bars
Low-cycle fatigue behaviour and strain-life model of stainless steel reinforcing bars Open
Reinforced concrete (RC) structures, often subjected to repeated static and dynamic loadings, are prone to fatigue failure of their steel reinforcing bars (rebar), which is worsened by corrosion in high chloride concentration service envir…

Conceptual study of an innovative friction damper for the seismic retrofit of precast RC structures with poor connections Open
Precast RC structures have been widely used in industrial and commercial buildings since the 60 s in the most developed areas. However, during those decades of economic growth, most buildings were constructed without seismic design criteri…
