The average value of the equivalent

The average value of the equivalent viscous damping coefficient for the cast-in-place joint at peak load was 0.2413. The average viscous damping coefficients at peak load of the precast prestressed concrete joints PPCJ1 and PPCJ2 were 0.2340 and 0.2470, respectively. The equivalent viscous damping coefficient was close for all joints. This similarity indicates that the energy dissipation capacity of the precast prestressed concrete joint was similar to that of the cast-in-place joint. Thus, the precast prestressed concrete joint had the same energy dissipation as the equivalent monolithic system.
