Static analysis of non-planar pierced shear walls with semi-rigid beam-wall connections using continuous connection technique
The lateral loads acting on high-rise reinforced concrete buildings are often resisted by specially arranged shear walls. Pierced shear walls weakened by doors, windows and corridors, necessitate particular attention, since they are highly indeterminate. In this study, the static analysis of non-planar pierced shear walls with yielded connections modelled as equivalent rotational springs is considered. To carry out a quick predesign of non-planar pierced shear walls, an elegant technique called Continuous Connection Technique (CCT) has been used in conjunction with Vlasov's theory of thin-walled beams. The governing differential equations, in the CCT, are the compatibility equations written for the vertical displacements at the midpoints of the connecting beams. There is a contribution pertaining to the semirigid beam-wall connections in these equations. The connecting beams are assumed to have the same properties and spacing along the entire height of the wall and all rotational springs have equal constants. ©2010 Academic Journals.
