Abstract

Seismic behaviour of r/c columns and beams with interlocking spirals M.A. Tsitotas, LA. Tegos Department of Structural Engineering, Aristotle University Thessaloniki, 540 06 Thessaloniki, Greece SUMMARY Columns of a rectangular cross-section with interlocking spirals are the latest development in bridge-building, where they are applied on piers of high earthquake-resistance requirements. This method can also be applied even on soft stories of buildings, like pilotis. Flexural behaviour of structural elements in general, with interlocking spirals, but mainly their behaviour due to shear, must be further investigated, analytically and experimentally. This study refers to this problems, comprising an experimental and an analytical part. More precisely in the experimental part, the response of columns and beams with interlocking spirals is compared to the response of conventionally reinforced ones, and useful conclusions are drawn on the performance of these structural
