| Abstract | This present study shows the effect of Energy Dissipating Cladding System (EDCS) on the structure's seismic behavior and develop improved low damage cladding-frame system. Cladding panels are designed by isolating it from structural system using either flexible or slotted connection reducing its possible interaction with the structure to minimize cladding damage. However, it is still found to have interaction between the facade and the structural system. This study exploits the interaction by integrating EDCS to minimize damage. The EDCS consists of full-height pre-cast cladding panel incorporated with viscoelastic damper (YED). This system when incorporated into the building frame behaves as a bracing system and source of energy dissipation without having to use inelastic property of the structural system during seismic event. This study shows the effects of EDCS incorporated into struc- tural system of lO-story, 6-bay steel ordinary moment frame (OMF). YED is designed as the main energy dissipator by implementing it at the connection and a new EDCS system is designed where cladding provides additional stiffness to the system. Analysis has been done using seven time-history and the designs are based on the average response of seven earth- quake. This research contains four main study;design of EDCS in building retrofit; design of new EDCS frame; comparison diagonally braced frame and EDCS frame; and sensitiv- ity of a designed damper stiffness. From non-linear time history analysis, It was found that EDCS proved to be effective in reducing inters tory drift and member forces. EDCS frame also performed better compared to VED braced frame in reducing member forces. There- fore, the combined behavior of energy dissipation from VED and supplemental stiffness from cladding can be integrated together in a cladding frame to reduce damage and improve seismic performance of a building. |
