Damage response of conventionally reinforced two-way spanning concrete slab under eccentric impacting drop weight loading

open access: yesDefence Technology, 2023
Reinforced concrete (RC) structures are generally designed to carry quasi-static gravity loads through almost indispensable components namely slab, however, it may be subjected to high intense loads induced from the impact of projectiles generated by the

Was it an Earthquake? [PDF]

open access: yesNature, 1886
YESTERDAY morning (Thursday, April 8), at 5.35, the door of my room vibrated regularly for about three or four seconds. I did not perceive any motion of the room itself. I was up at the time, and quite still. Perhaps the best way of finding out whether anyone else experienced anything of the same nature, so as to determine whether it was in any way ...

A possible characteristic of foreshocks derived from the evaluation of loading/unloading induced by earth tides

open access: yesFrontiers in Earth Science, 2022
The detection of the potential of a larger event immediately after a moderate earthquake is a quite difficult problem. In this work, we devised an approach to determine whether an earthquake is a foreshock to a larger mainshock by evaluating loading ...
