Abstract :
Aimed at better understanding the seismic behavior of reinforced concrete (RC) walls, typically used in one-to-two stories housing in several Latin American countries, a large investigation project has been carried out. Previous experimental programs considered the behavior of walls subjected to monotonically and cyclically increased loads. This paper compares and discusses displacement and shear strength capacities, as well as the dynamic characteristics of six RC walls tested under shaking table excitations. Variables studied were the wall geometry (solid walls and walls with openings), type of concrete (normalweight and lightweight), web steel reinforcement ratio (0.125% and 0.25%) and type of web reinforcement (deformed bars and welded-wire mesh). Shaking table tests were essential for assessing dynamic characteristics, such as changes in fundamental frequencies and damping factors of RC walls for low-rise housing.
