Shear walls optimization in a reinforced concrete framed building for seismic risk reduction

Seismic hazards represent a permanent threat to buildings. The paper argues that risk-oriented approaches provide an interesting solution account for the long-term resilience of buildings, both design new structures and rehabilitation existing ones. proposed research draws upon standard definition risk as function vulnerability, hazard exposure develop optimization-based methodology appraisal buildings in seismic conditions. allows identify optimum layout thickness shear walls reinforced concrete frame, based on target performance. This is achieved through coupling evolutionary computing environment with object-oriented structural analysis tool, involving its native Application Programming Interface (API). latter automate search wall configuration solution. validated Beichuan Hotel building Old (China), heavily affected by 2008 Wenchuan Earthquake. evidences adoption leads reduction about 80% compared as-built scenario, additional benefits from financial functionality perspective.
