SIZE EFFECT ON STRAIN ENERGY ABSORPTION CAPACITY OF REINFORCED HIGH STRENGTH CONCRETE COLOMUNS UNDER UNIAXIAL COMPRESSION LOADING
タイトル（掲載誌）愛知工業大学研究報告. B, 専門関係論文集 = Bulletin of Aichi Institute of Technology. Part B
一般注記In the present study, the effect of specimen size on the absorption energy of RC colomns is discussed based on the reported test data of reinforced high- and ultra-high strength RC rectangular columns reported earlier by the authors and the new data of ultra-high strength RC cylindrical columns. Experimental factors include the section size of specimen (b=9.7,15,20 and 25cm for square cross sections, D=10,15,20 and 25cm for circular cross sections), concrete compressive strength (Fc=700 and 1000kgf/(cm)^2), the six types of hoops, pitch of hoops (S=∞, b/4,b/6 and b/8) and yield strength of hoops (σy=3000,5000 and 15000 kgf/(cm)^2 level). Following statements can be drawn from the test results. 1) The absorption energy up to failure Wp of RC columns increses with incresing concrete compressive strength and the magnitude of lateral confinement, which depends on the pitch, yield strength and shape of hoops. 2) Size effect on the absorption energy up to failure Wp of RC columns is rather small when the magnitude of lateral confinement is very high, or the value of Wp itself is large.
