| Popis: | The bonding connection in steel–concrete composite beams is investigated in the case of static loading and normal strength concrete. Two 3-point bending tests performed on 4 meter span beams confirm that bonding could be very efficient allowing a large plastic strain without any shear failure if the bonding joint is properly designed. The measurements are close to the numerical results provided by non-linear beam models or non-linear FE model. However all the studied beam models do not allow a very accurate prediction of the behaviour close to the interface at failure in the case of shear failure. A realistic shear failure criterion suitable for bonded composite beams may improve numerical results. |
