The construction industry is the primary reason for resource consumption and CO2 emissions worldwide. Post-earthquake resiliency is a key to reducing such impact. However, repairing a damaged building is still too expensive and, in most cases, unpractical after a strong earthquake. There is a large body of research related to dissipative systems (and repairable in a few cases), claiming good structural characteristics. However, there has not been yet major evidence in putting the research findings into practice, increasing the reliability of the technical and economic data needed for industrial and commercial use. EU-RFCS DISSIPABLE (2018-2022) is a pilot/demonstration project that aimed to improve the steel building industry's long-term sustainability and resource efficiency by increasing the post-earthquake resiliency of steel-concrete composite structures. The project focused on dissipative and repairable components made of steel elements (pins, plates, short beams) that any steel manufacturer can easily reach.
In this workshop, the following results will be presented and discussed with the participants:
• Full-scale hybrid tests based on numerical/physical simulation.
• Shaking table tests of 3D building specimens under natural seismic excitations.
• Benefits of high strength steel and stainless steel for seismic resistant steel structures
• Embodied CO2 and cost comparisons between the tested and conventional buildings based on the life cycle inventory collected during the 4-year project.
• Design guidelines and instructions for use showing a systematic assembly, removal, repair and reassembly procedures of the dissipative elements.
