Abstract
Key aspects for the design of seismic resistant steel and composite steel-concrete structures are the utilization of the steel material ductility as well as the selection of the appropriate structural system. These will allow for effective redistribution of the internal forces and dissipation of the energy induced to the structure by earthquake.
Aims of the project are (i) the development of prequalified, dissipative, partial-strength bolted beam-to-column joints for steel and composite structures and for use primarily in Moment Resisting Frames and (ii) the preparation, on the basis of the performance-based-design concept, of design guidelines for certain structural systems regarding the allowable deformations and their energy dissipation capacity. Additionally, when referring to low-to-moderate seismicity areas, criteria for the assessment of the need for energy dissipation in the structure will be developed. These investigations involve numerical studies as well as cyclic joint tests and static reference tests.
The project aims to selectively adopt already known, valuable principles of seismic design and develop new ones, applicable for areas of up to medium seismicity.
