Unreinforced masonry wall collapse in non-rehabilitated specimen (left), less damaged, rehabilitated specimen (right)

A shaking table test, a part of international joint research project with Turkey and Germany, was carried out to develop a seismic rehabilitation scheme of reinforced concrete frame with an unreinforced masonry wall for strengthening its out-of-plane capacity. Both non-rehabilitated specimen and rehabilitated specimen were tested on shaking table. From the results, the effectiveness of the rehabilitation scheme was verified.

Test set-up

Specimen after failure

This experimental study was carried out to establish methodologies to evaluate the residual axial capacity of reinforced concrete columns after shear failure. From the results, the mechanism of column resistance against axial force was clarified and accurate formulas to evaluate their residual axial capacity were established.
