Numerical simulation on seismic pounding damage in a simply-supported steel bridge [PDF]
Heliyon, 2023 Steel bridges are generally considered to perform well during seismic activity. Nevertheless, they still suffered much unexpected seismic damage in the Kumamoto earthquake, especially seismic pounding damage.

On critical pounding mechanism of base-isolated buildings using an optimized multi-hazard method
Results in EngineeringIn 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 ...

Assessment of seismic vulnerability of RC frames at the end-of-row of buildings with floor-to-floor alignment using multi-strips analysis MSA [PDF]
JES: Journal of Engineering Sciences, 2022 During earthquakes’ excitation, adjacent buildings start vibrating out of phase (in different directions) leading to collisions with each other causing severe damage in a phenomenon known as structural pounding.

Pound for Pound Export Diversification [PDF]
SSRN Electronic Journal, 2020 We propose a short-run model of the extensive margin of trade and deploy it to distinguish and quantify domestic and cross-border margins. Our empirical focus is on the domestic extensive margin of trade (domestic distribution of a product) and its importance for quantifying policy and globalization effects on the international extensive margin of ...

Study on Pounding Response of Adjacent Inelastic SDOF Structures Based on Dimensional Analysis
Advances in Civil Engineering, 2021 The dimensional analysis method is applied to study the pounding response of two inelastic single-degree-of-freedom (SDOF) structures under simplified earthquake excitation. The improved Kelvin pounding model is used to simulate the force and deformation

Collision in the expansion joint effects on the seismic behavior of large-scale aqueduct
Journal of Asian Architecture and Building Engineering, 2021 Under earthquake, two beams of the aqueduct’s expansion joint may collide; thus, this will endanger the safety of the structure and even lead to girder falling accident.
