Abstract:

A shear wall has been the most common structure system used to stabilize building structures against horizontal forces caused by wind or earthquake. With the advent of reinforced concrete, shear wall systems have become widely used to stabilized efficiently, even the tallest building structures, by gaining concrete strength over 130MPa. A common shear wall system used for tall office buildings groups shear walls around the service core, elevator shafts and stairwells to form a stiff box structure. In contrast with office buildings, high-rise residential buildings have fewer demands for elevators, lobbies, and services. Hence, they do not usually have large stiff concrete shear wall boxes to resist horizontal forces. A more common system will incorporate a small box structure around a smaller number of elevators and stairwells and include discrete shear walls between apartments. To design shear wall arranged service core, the bending, shear, and warping stresses due to wind or earthquake loads are combined with stresses due to gravity loads. The box system's walls can then be designed as unit length wall spanning either floor to floor and between return walls.
