Seismic pounding mitigation of a modern heritage R/C bell tower [PDF]

open access: yes, 2013
Pounding is one of the greatest sources of seismic vulnerability of pre-normative R/C structures, as they have often been built at poor distance from adjacent buildings.

Concept, Tests, and Optimum Design of Novel Negative Stiffness Friction Dampers for Seismic Protection of Long‐Span Bridges

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2719-2741, September 2026.
ABSTRACT Viscous dampers (VDs) are widely used to mitigate the excessive responses of long‐span bridges. However, VDs face some intricate challenges in engineering practices, including high damping coefficient requirement, potential base shear amplification and tremendous damping force under high velocity. To address these issues, this study develops a

Damped interconnection-based mitigation of seismic pounding between a R/C tower and a masonry church [PDF]

open access: yes, 2013
Damped interconnection represents an advanced strategy to mitigate the effects of seismic pounding between adjacent structures built at poor mutual distance. The effects of pounding can be particularly severe in slender R/C structures, including civic or

Evaluation of the Adequacy of Design Specifications for Nonstructural Components in a Reticular Structure

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 10, Page 2132-2150, August 2026.
ABSTRACT Nonstructural components (NSCs) installed in large‐span reticular structures were frequently severely damaged during earthquakes, even when the primary structure remained intact. Existing seismic design specifications for NSCs were predominantly developed for upright structures such as multi‐storey buildings and offer no guidance for reticular

The Effect of Magnitude Mw and Distance Rrup on the Fragility Assessment of a Multistory RC Frame Due to Earthquake-Induced Structural Pounding

open access: yesBuildings, 2023
The effect of an intensity measure’s (IM’s) sufficiency property on the probabilistic assessment of reinforced concrete (RC) structures due to floor-to-floor structural pounding conditions is examined.

Development of Full‐Scale Experiment‐Based Seismic Fragility Functions for Code‐Compliant Fire Sprinkler Piping Systems

open access: yesEarthquake Spectra, Volume 42, Issue 3, August 2026.
Fire sprinkler systems are critical for fire safety, but their functionality can be impaired by seismic damage. This study develops new seismic fragility functions for acceleration‐sensitive damage requiring monitoring, maintenance, and repair in code‐compliant fire sprinkler piping systems, using experimental data from full‐scale experimental tests ...

State-of-the-art review on seismic induced pounding response of bridge structures

open access: yes, 2013
Seismic induced pounding damage to bridge structures was repeatedly observed in many previous major earthquakes. To avoid this adverse effect, extensive research efforts have been made by many researchers. This paper presents a state-of-the-art review in

Seismic Pounding between Three Adjacent RC Buildings Considering Soil-Structure Interaction [PDF]

open access: yesJES: Journal of Engineering Sciences
In highly populated cities, the close spacing of buildings often results in interaction effects, including structure–soil–structure interaction (SSSI) and seismic pounding (SP), which occur because of the limited gaps left between adjacent structures. In

Enhancement of Seismic Resilience of Structures With Tuned Mass Damper Inerter by Using Effective Damping Ratio

open access: yesEarthquake Spectra, Volume 42, Issue 3, August 2026.
This study investigates the performance of a tuned mass damper inerter (TMDI) in enhancing the seismic performance of structures by focusing on the concept of effective damping ratio (EDR) and its enhancement through the effective damping ratio enhancement (EDRE) approach. An analytical model is developed for a single‐degree‐of‐freedom system subjected

Regional Seismic Wavefield Propagation [PDF]

open access: yes, 2004
Through the examination of local and regional seismic waveform data the crust and upper mantle of southern California are investigated. Using local and regional seismic phases such as Pn, Sn, PL, and surface waves, seismic wave velocities of interesting
