Architectural precast concrete construction relies on mechanical connectors at discrete location that may be damaged in a blast or seismic event, posing specific design problems to the engineer. These problems can be overcome with proper detailing. The performance of precast concrete cladding wall panel connection details may be enhanced by incorporating a specific connection hardware, herein described, that deforms elastically or inelastically to accommodate relative displacements due to building motion and/or energy associated with blast pressures.

This invention relates to a positioning apparatus for an upright panel of a building, the apparatus comprising a base adapted to depend from a structure associated with the building or construction thereof, a support for an edge of the panel, and a positional adjustment means depending from the base which provides for positional adjustment of the support relative to the base. A system for positioning a precast panel which incorporates the apparatus, along with methods for using the apparatus and method are also disclosed.

A building faade is secured to a building structure having a plurality of vertically stacked levels defined by horizontally arranged floors therebetween. The faade includes a framework which is mounted to one or more of the floors and one or more cementitious faade panels which are mounted to the framework. The cementitious faade panels include a cementitious planar member and a glazing frame secured to the cementitious planar member. The cementitious faade panels are mounted to the framework by adhering the glazing frame to the framework. The framework can be mounted to one or more of the floors before or after the cementitious faade panels are mounted thereto. Preferably, the glazing frame is adhered to the framework by structural spacer tape and/or structural sealant, and the glazing frame includes anchor studs embedded in the cementitious planar member.
