Some notes and sketches on SHEAR WALL.

DIFFERENT PLAN CONFIGURATION OF SHEAR WALLS AND CORE WALLS.

Forces acting on and within a shear wall.

A transfer diaphragm provides a force path for horizontal shear forces from the upper wall to the offset ground floor wall.

A curved bond beam behaves differently depending on the direction of horizontal force.

How foundations resist overturning moments and shear forces from a vertical structure, in this case a shear wall. Common shear wall materials, their typical ranges of height and general comments

The forces within a confined masonry wall.

Ground floor plans of a four and an eight-storey building showing the structural footprints first for gravity forces only, and then for seismic forces where resisted by shear walls and moment frames.

Ground floor plans showing different shear wall layout options that provide symmetrical resistance for x direction seismic forces (Y direction and gravity structure not drawn)
