RESTORING FORCE CHARACTERISTICS OF REINFORCED CONCRETE SHEAR WALLS
|
´˜^i‰pjF
The results of a laboratory investigation on the restoring force characteristics of reinforced concrete shear walls surrounded by a frame for low-rise buildings are presented. Seventeen medium-size shear walls were subjected to static loads representing gravity and earthquake loads. The variables were wall reinforcement ratio, gravity load and loading history, that is, cyclic deflection amplitude and a number of cyclic loading. The results suggest that the restoring force characteristics of reinforced concrete shear walls can be modelized by the combination of envelope curve and the hysteresis loops corresponding to the deflection levels.
