FUSEIS PIN LINKS: INFORMATION BROCHURES AND DESIGN OF CASE STUDY

Abstract eng:
In the frame of the INNOSEIS research project, which is funded by RFCS, information documents for INERD-pin and FUSEIS-pin links have been produced by NTUA for dissemination to all partners of the construction sector such as architects, structural engineers, construction companies, steel producers and all potential decision makers of the construction sector. For each of the two systems, an approximately 40-page information brochure has been drafted in English. They contain a description of the main features of the system, overall dimensions, preferred structural materials, range of sizes, member shapes, typical cross sections and limitations, possible arrangements for conceptual design, recommended structural details etc. and indicative application examples of selected building structures. In addition, information is given regarding the non-linear force-deformation characteristics and ductility/strength capacities of the systems, the hysteretic behavior of elements under cyclic loading, including rules for stiffness and strength degradation. Finally, pre-normative q-factors are proposed and reference is made to application examples in design practice, previous publications and literature. Case studies on the seismic design of steel buildings incorporating the systems are presented. FUSEIS pin links have been applied on a 2-storey and on a 4-storey office steel building while INERD pin connections have been applied in an existing 6-storey commercial reinforced concrete building. Each case study refers to the conceptual design, loads and load combinations, modelling, analysis, detailed design and structural detailing. Design follows the provisions of the Eurocodes and the pre-normative guidelines that were developed within the project. The existing building was designed according to an outdated national seismic code. It does not comply with the requirements of EN 1998-1, hence the need for upgrading.
