In this paper, twenty-one high-strength concrete cylinder specimens with diameter of 150 mm and 300 mm in height were cast, laterally pre-tensioned with steel strap in different confining layers and tested to failure under uniaxial cyclic and monotonic compression loading. of any study addressed the uniaxial cyclic response of such confinement. A number of studies have been reported the behaviour of SSTT-confined concrete under uniaxial monotonic compression loading but none. The remarkable advantages and promising increment in concrete ultimate capacity as well as ductility by using steel straps as lateral confinement has brought the steel strapping tensioning technique (SSTT) as one of the most affordable confining technique in market. The examples run and the comparisons made prove the effectiveness of the proposed numerical procedure. In order to illustrate the pro-posed method and its accuracy and efficiency, this program was used to study several representative examples, which have been studied previously by other researchers. A computer program was developed, aimed at obtaining the ultimate strength capacity and reinforcement required by rein-forced and composite cross-sections subjected to combined biaxial bending and axial load. paper shows very good stability in the presence of strain softening effect exhibited by the concrete in compression and tension and convergence stability is not affected by the shape of stress-strain relation-ships of concrete, the type and amount of reinforcements or the residual stress distribution in encased steel elements. The new numerical procedure developed in this. The design procedure allows cross-sections to be designed by solving directly for the reinforcement required to provide a cross-section with adequate strength. This paper presents an efficient numerical procedure for the rapid design of arbitrary-shaped composite steel-concrete cross-sections that are subjected to biaxial bending and axial force.
