Potential HEPM donor cells (2000 to 4000) were pulse labeled with 3H-uridine (10 microCi/mL; 3 hr) and then cocultured for 3 hr with 200,000 to 400,000 potential recipient cells in the absence or presence of 2-methoxyethanol (ME; 0.13-0.30 M) or 2-isopropoxyethanol (IPE; 0.05-0.1 M).
Open image in new window Fig. 14 a Circular SRCFT (C 2 IPE), b square SRCFT (S 2 IPE).
Circular SRCFT column reinforced with IPB (120, 160, 200) steel section, 2 IPE steel section, and cross-shaped steel section, respectively = CB (120, 160, 200), C 2 IPE, C-Cross.
Square SRCFT column reinforced with IPB (120, 160, 200) steel section, 2 IPE steel section, and cross-shaped steel section, respectively = SB (120, 160, 200), S 2 IPE, S-Cross.
Then, three types of circular SRCFT columns (C-Cross, CB 200, and C 2 IPE) and square SRCFT (S-Cross, SB 200, and S 2 IPE) columns of each groups with the same cross-sectional area of reinforcing steel sections (IPB200, 2 IPE, and cross section) have been analyzed.
Considering the results, C-Cross, C 2 IPE, and CB 200 sections have the higher amount of moment of inertia, higher shear strength, and energy absorption capacity, respectively.
Furthermore, columns C-Cross, C 2 IPE, and CB 200 showed the best performance with regard to stiffness, the maximum shear strength, and energy absorption capacity, respectively.
In addition, C-Cross, C 2 IPE, and CB 200 specimens showed the best performance regarding stiffness, ductility, and energy absorption capacity, respectively.
Figure 18 shows that C-Cross, CB 200, and C 2 IPE sections have the higher amount of shear strength, respectively.
Figure 13a shows that the yield load and stiffness of C-Cross specimen are higher than that of the CB 200 and C 2 IPE specimens.
