Seismic Performance of a Green Roof Structure

Sustainability addresses the need to reduce structure’s impact on environment but does not environment’s structure. To explore this relationship, study focuses quantifying of green roofs or vegetated seismic responses such as story displacements, interstory drifts, and floor level accelerations. Using an archetype three-story steel moment frame, nonlinear time history analyses are conducted in OpenSees for a shallow deep roof using suite ground motions from various distances fault identify key trends sensitivities response.
