CONSIDERATION OF POUNDING AND SSI IN ENERGY-BASED SEISMIC DESIGN OF BUILDINGS [PDF]
The energy demand on a given construction is commonly determined, in terms of equivalent velocity, from smoothed design spectra that are ordinarily derived after dynamic analyses on SDOF systems. The application to actual multi-story buildings is far from trivial, given that their behavior must be characterized with MDOF models; in this context, a ...

Damage-Involved Structural Pounding in Bridges under Seismic Excitation
During severe earthquakes, pounding between adjacent superstructure segments of highway elevated bridges was often observed. It is usually caused by the seismic wave propagation effect and may lead to significant damage.

Cross‐Entropy of Power Spectral Density Function: A Modal Identification Framework
ABSTRACT The power spectral density (PSD) function of measured structural response contains a significant amount of information, including the modal parameters (natural frequencies, damping ratios). Output‐only system identification or modal identification technique can be used for extracting such modal parameters from the measured response or its ...

ABSTRACT Conventional single intensity measure (IM) fragility approaches with simplified component dependency assumptions overlook the progressive damage accumulation and evolving inter‐component correlations that govern system behavior under mainshock‐aftershock (MSAS) loading.

Seismic Study of An Isolated Cable-Stayed Bridge under Near-Fault Ground Motions
During strong earthquakes, pounding may occur on large-span bridges and their approach bridges. The effect and mitigation measures of such pounding have rarely been explored in previous studies.

Pounding effects during an earthquake, with and without consideration of soil‑structure interaction [PDF]
The pounding between adjacent buildings can cause both architectural and structural damages. The paper presents some aspects related to the Vrancea seismic motions pattern, a review of observed damages after a strong earthquake due to pounding of ...

ABSTRACT Seismic fragility assessment of reinforced concrete (RC) bridges exposed to corrosive environments must reliably capture time‐dependent deterioration impacts. Climate change compounds this challenge through nonstationary temperature and humidity variations that accelerate bridge corrosion.

On critical pounding mechanism of base-isolated buildings using an optimized multi-hazard method
In many studies on the effect of pounding on isolated structures, the failure to consider all potential pounding scenarios, including floor-to-floor (FF), floor-to-column (FC), and pounding with a moat wall, can introduce uncertainty into the obtained ...

This paper explores how climate‐resilient technologies, such as smart grids, digital twins, and self‐healing materials, can enhance urban resilience. It highlights the urgent need for proactive planning, public‐private collaboration, and data‐driven innovation to future‐proof underground infrastructure amid accelerating climate and urban pressures ...
