Abstract
The potential lateral stiffness contribution of heavy-weight claddings on buildings and the role of cladding in altering dynamic properties and linear seismic response were investigated. The prototype structure studied was a 24-story steel frame office building of core construction with a contoured precast panel facade. Results obtained from a sheer stiffness model were compared to those obtained from three-dimensional finite element models. Lateral stiffness was shown to be heavily dependent on details of the panel-frame attachment. The addition of cladding models to conventional frame models of highrise buildings was found to alter predicted overall structure frequencies and linear seismic response.
