THIN STEEL MANTLE AS LATERAL CONFINEMENT IN REINFORCED CONCRETE COLUMNS, TEST RESULTS . NORDIC CONCRETE RESEARCH. PUBLICATION NO 8

This paper presents an experimental investigation on the effect of a steel mantle on strength and deformation behaviour of eccentrically loaded high strength concrete columns. Circular concrete columns of 250 mm diameter with a thin steel mantle were studied with references in spirally reinforced columns. Concrete compressive strength in the main series was 85 MPa and in reference series 45 MPa. Test results are compared to load-moment interaction diagrams calculated using stress-strain relationships from the new Norwegian Code NS 3473 'Design of Concrete Structures' published in 1989. The test results showed that a steel mantle improves moment-rotation characteristics and prevents a brittle type of failure.(A) For the covering abstract see IRRD 828653.
