Dear Experts,

I want to know the roll of Cladding System in tall buildings. How do cladding system interact frame elements. If u have any papers in reference to role of cladding in tall buildings please enlighten us with it.

Thanks
Raqueeb.

SUMMARY
建筑包层提供了潜在的passive response modification in building structures designed to resist seismic loadings. The cladding connections can be designed to dissipate energy through inelastic material hysteresis driven by seismically induced interstory drift. When properly designed, precast cladding panels can easily support the added interstory forces and the ductile connectors can stably dissipate energy without compromising connection integrity. From a design point of view, this passive response modification can be used to (a) improve serviceability or (b) reduce cost. Improved serviceability is achieved by optimizing the
connectors to maximize energy dissipation and consequently to reduce the peak drift. Reduced cost, as measured by reduced structural weight, is achieved by starting with a baseline structural
design and systematically reducing member sizes while adding passive damping in the connectors while maintaining the same baseline performance (as measured by peak drift). Approach (a) is shown to reduce peak displacements by more than 40% from baseline values and has potential for both new and retrofit/rehabilitation applications. Approach (b) is shown to
reduce structural weights in new designs by at least 14% for the most conservative design assumptions.
