A method is described for constructing a concrete building from precast concrete wall and floor panels. Each floor construction has a plurality of spaced-apart dowels which project upwardly above its surface along the proposed joint between the floor and a proposed wall, and each of the wall panels includes along its length vertical voids which extend for its full height at a spacing from one another generally the same as the spacing between the dowels projecting upward from the floor construction. The load bearing walls of the building are formed by erecting wall panels for the same vertically at the proposed joint with the dowels extending into the wall panel voids. Reinforcing rods are introduced into the voids to overlap the ones projecting upward from the floor, and the voids are filled with mortar to tie each of such wall panels to the floor below. A mortar junction resistant to horizontal shear forces is formed between the floor construction and the wall panel at the time the panel is otherwise interlocked to the floor to resist vertical stress forces. The floor construction is formed by supporting floor panels horizontally adjacent one another spanning the space between a pair of parallel, load bearing wall panels. Post-tensioning cables are positioned between and threaded through such floor panels, and recessed keyways are provided at the joints between adjacent panels. Mortar placed in such joints interlocks the adjacent panels to resist horizontal shear stresses, and the cables are post-tensioned to otherwise support and tie the floor panels together to resist vertical loading and seismic forces.

In a method of forming a concrete building, the steps of erecting a pair of load bearing wall panels generally parallel to and spaced apart from one anOther; supporting at least two floor panels for a floor construction horizontally adjacent one another on said walls spanning the space therebetween placing a post-tensioning cable for said floor construction along the joint between said adjacent floor panels transverse to said load bearing walls with the portions of said cable over said walls positioned vertically above a portion of said cable positioned over the space between said walls; filling the joint between said adjacent floor panels with mortar; and post-tensioning said cable after said mortar is set. In a method of forming a concrete building, the steps of: forming a horizontal base structure with a plurality of spaced apart dowels projecting thereabove along a pair of proposed joints between said structure and a pair of proposed load bearing walls, which joints are generally parallel and spaced apart from one another; providing a pair of preformed wall panels having voids extending vertically therethrough at a spacing from one another generally the same as the spacing between said dowels at said proposed joints; placing each of said wall panels respectively along an associated one of said proposed joints with the base structure dowels at said associated joint projecting into an associated wall void; inserting a reinforcing bar into each of a plurality of said wall voids having a dowel projecting thereinto to a location at which said bar overlaps said dowel; supporting at least two floor panels for a floor construction on said two wall panels horizontally adjacent one another and spanning the space between said wall panels; placing a post-tensioning cable for said floor construction along the joint between said adjacent floor panels transverse to said wall panels with the portions of said cable over said wall panels positioned vertically above a portion of said cable positioned over the space between said wall panels; forcing mortar into each of said wall panel voids within which a reinforcing bar overlaps said dowels to tie each of said reinforcing bars to its associated dowel; filling the joint between said adjacent floor panels with mortar; and post-tensioning said cable in said joint after said mortar in said joint is set.
