Centrifuge modeling of rocking-isolated inelastic RC bridge piers [PDF]

, 2014
Experimental proof is provided of an unconventional seismic design concept, which is based on deliberately underdesigning shallow foundations to promote intense rocking oscillations and thereby to dramatically improve the seismic resilience of structures.

Optimum Location And Bracing System As Alternative To Shear Walls For Retrofitting Of RC Buildings Against Seismic Loading

Eurasian Journal of Science and Engineering, 2023
The defective structures must be retrofitted to resist the effects of earthquakes due to the potential risks connected with reinforced concrete structures designed in many parts of the world in accordance with codes that are now proven to guarantee ...

Interaction of Air Pressure and Groundwater as Main Cause of Sub‐Daily Relative Seismic Velocity Changes

Geophysical Research Letters, 2023
Our study investigates variations of seismic velocity that occur over short time scales of hours. We use coda wave interferometry to inspect 5 months of continuous data from a seismological array in southern Germany.

Analytical modeling of reinforced concrete columns subjected to bidirectional shear [PDF]

, 2017
Under general seismic loading, reinforced concrete columns may be subjected to lateral loads in more than one direction. Available experimental data on columns subjected to bidirectional forces indicate that higher levels of damage and a higher loss of ...
