Effects of green roof damping and configuration on structural seismic response

Frontiers of Structural and Civil Engineering   Pages 1133-1144 doi: 10.1007/s11709-023-0959-9

Abstract: The soil of a green roof can serve as a damper to dissipate the energy generated by earthquakes or otherResults of preliminary analysis show that a green roof soil can increase localized damping by 2.5% underconducted on a three-story building in SAP2000 to monitor the structural behavior with and without a green roofThe increased damping in the green roof soil is beneficial to the structural performance, i.e., it reduces
