The Measurement of P-, S-, and R-Wave Velocities to Evaluate the Condition of Reinforced and Prestressed Concrete Slabs

Table 3

S-wave velocities (m/s) at test grid points in slabs S1, S2, and S3.

Test point	S1				S2				S3
	AB	CD	EF	GH	AB	CD	EF	GH	AB	CD	EF	GH
I	1830	1870	2020	1800	2270	1790	1830	2320	1910	1930	1890	1900
II	1950	1870	1840	1780	1800	1790	2070	1800	1930	1810	1900	2030
III	1880	1840	1840	1900	1780	1800	1830	2050	1960	2040	1950	2010
IV	1890	2160	1890	1890	1840	2070	2150	1920	1890	1980	1970	2050
V	2020	1890	2010	2040	2110	2040	2040	1920	1890	2010	2010	1970
Min	1780				1780				1810
Max	2160				2320				2050
Avg (m/s)	1911				1961				1952
Std (m/s)	95				169				62

Avg = average velocity and Std = standard deviation.
