Table 1

Instruments of the experimental part.

Measure	Device	Location
Acceleration	Piezoelectric accelerometer KS77C.10 ± 600 g	At a distance of 200 mm from the centroid of the experimental specimen
Vertical displacement	LVDT	Position 200 mm from the midpoint of the underside of the slab
Strain in steel	KYOWA brand steel strain gauge	Within the sample, two steel bars are situated, with one positioned at the uppermost section and the other at the lowermost, maintaining a separation distance of 200 mm from the sample’s center
Strain in concrete	KYOWA brand concrete strain gauge	The offset from the central axis of the underside of the specimen’s hammer measures 200 mm
