- Abstract
- Seismic behavior and design of heavy facades/claddings and connections in buildings has been investigated, and unique cyclic racking tests of representative precast concrete facade/cladding panels and connections have been carried out. Test results consist of cyclic load-displacement curves; time-history plots of loads, displacements, accelerations, etc., during each test; analysis of peak response quantities, e.g., displacements and load-levels reached; estimated rigidities of the cladding panel-connection assembly at increasing levels of peak displacements of block cycles; as well as the relationship between drift levels and behavior of cladding panel-connection assemblies. Dynamic testing of a representative reduced scale three dimensional model two story steel-framed building structure with and without precast concrete cladding panels, was carried out. Results provide quantitative experimental data on the earthquake resistance and stiffness of cladding connections and the overall seismic behavior of cladding connection assemblies.
