Experimental activities in framework of SERA - INMASPOL project

The Institute of earthquake engineering and engineering seismology in Skopje as a part of SERA (Seismology and Earthquake Engineering Research Infrastructure Alliance for Europe) participated in three scientific projects ( INMASPOL, SC-CBF and Influence of the floor-to-wall interaction on the seismic response of coupled wall systems) as research centre offering its capacities and laboratory equipment from the department Dynamic testing and informatics.

The project assessed the efficiency of the innovative intervention method through testing of full-scale masonry infilled RC building on shaking table. The seismic tests validated in-plane and out-of-plane infill performance when modified, repaired, or strengthened with PUFJ (Polyurethane flexible joints) and FRPU (Fiber reinforced PU) systems. The project was successfully realized, and valuable data was obtained.

The test specimen was one fully symmetrical 3D frame of one storey with 4 RC columns, 4 beams, a slab and 4 infill masonry walls constructed, all designed according to current Eurocodes. The real scale building had plane dimensions of 2.7×2.7m and total height of 3.25m. It was exposed to many seismic tests on the shaking table, using the scaled Kefalonia earthquake record as well as random and sine sweep excitations to determine the change of the dynamic characteristics.
