| Abstrakt: |
Support conditions, specifically axial restraint, have a significant impact on the behaviour and load carrying capacity of flexural members such as slabs. However, in conventional design these beneficial effects are ignored since they cannot be accurately quantified. In the current work two reinforced concrete one-way slab specimens were tested in three point bending with and without axial restraint. Each specimen was instrumented with distributed fibre optic strain sensors to assess the impact of the support conditions on the internal strain behaviour. The load deflection data for the two specimens is used to assess the impact of the support conditions on stiffness and capacity. The internal strain data is used to evaluate the degree of support restraint and the impact on the internal stress state for each specimen. |
