Abstract:
Explicit formulation for the flexural strength of a shear wall with boundary elements is presented. This development is based on the material properties conforming to the Indian Standard, but the underlying principle applies to other international standards, as well. Integral action of web and boundary elements is retained using the Bernoulli’s assumption of plane section along with the principle of mechanics. Design charts with normalized force and normalized moment as the axes are constructed using this explicit formulation and based on a few normalized geometrical parameters. Various combinations of grade of steel and grade of concrete are used for the construction of design charts to serve dual purposes. Design charts first offer an assessment of the approximate framework generally adopted in seismic design of shear walls with boundary elements involving a force-couple idealization. Interaction charts also offer a handy and offhand tool that best suite to the design office applications. Rectangular shear walls are also considered in the construction of design charts for completeness.
