Abstract

Abstract

In order to study the influence of prestress, shear-span ratio and vertical girder spacing on the shear properties of new type prestressed trussed steel-reinforced concrete beams, in this paper, five prestressed trussed steel reinforced concrete beams and one non-prestressed trussed steel reinforced concrete beam were designed and fabricated for the static shear test. The cracking load, ultimate load and deflection deformation of specimens were studied. The experimental results showed that the application of pre-stress and the reduction of the distance between vertical webs improved the shear capacity of members and effectively limited the generation and development of cracks, while the shear capacity of members decreased with the increase of the shear-span ratio. Based on the shear failure mechanism and experimental data, the shear bearing capacity formula of prestressed trussed steel-reinforced concrete beams was presented for engineering design reference.
