In tall buildings, lateral forces, induced by wind and earthquake, are generally resisted by shear walls. A solid shear wall can, easily, be accounted for as a cantilever beam. However, shear walls pierced by doors, windows and corridors are harder to analyze since they are highly indeterminate. As a result of their high resistance to lateral forces, shear walls have become very popular in tall buildings.
In this study, the static analysis of flexibly connected non-planar non-symmetric pierced shear walls is carried out by a simplifying method widely used in the past for the static analysis of similar structures [1]. This method, called the Continuous Connection Technique (CCT), comprises an elegant tool for the predesign computations related to the treatment of high-rise buildings. In this method, the connecting beams are assumed to have the same properties and spacing along the entire height of the wall. The constant of the equivalent elastic rotational springs to model the plastically deformed beam-wall connections is assumed to be determined by suitable experiments and are assumed to have the same value at all connections in the shear wall. Consequently, the discrete system of connecting beams can be assumed to be replaced by continuous laminae of equivalent stiffness capable of transmitting action of the same type as the connecting beams. The properties of the structure are expressed as continuous functions of the longitudinal coordinate by employing the foregoing model.
