Experimental Study of the Seismic Performance of L-Shaped Columns with 500 MPa Steel Bars

Table 1

Material property of steel bars and concrete of the L-shaped columns.

Specimen	Reinforcement				Concrete
	Bar	Yield strength/MPa	Ultimate strength/MPa	Elastic modulus/(10^5 MPa)	Cubic compressive strength/MPa	Prism compressive strength/MPa	Elastic modulus/(10^4 MPa)
L-shaped column (500 MPa)	500D8	519	800	2.01	51.6	31.6	3.35
	500D16	587	747	2.01
L60-400	HPB235D8	372.9	454.4	2.13	56.0	37.5	3.90
	HRB400D18	473.5	647.3	2.20

500D8 and HPB235D8 are, respectively, stirrups of L-shaped columns with 500 MPa bars and with HRB400 bars; 500D16 and HRB400D18 are, respectively, longitudinal bars of L-shaped columns with 500 MPa bars and with HRB400 bars.
