Layered Beams

The building of structures from steel fibre reinforced concrete (SFRC) in the external and conventional rein­forced concrete (RC) in the internal layer represents an economical alternative of structures effectively using SFRC. The paper presents test results of flexural behaviour of layered beams with SFRC external layers and RC internal layer. The behaviour of these beams is compared to test results of SFRC and conventional RC beams. The test results show, that the flexural load capacity for all series of beams is nearly similar, but the deflections of layered beams are less comparing to monolithic ones. It also been shown that the equations indicated in the Eurocode 2 can be used to design the flexural reinforcement in layered SFRC beams.

Unsaturated Polyester Resin Mortar

This research is aimed to investigate the flexural behaviour of patched reinforced concrete beam with patching material made from unsaturated polyester resin mortar. The variable studied is the dimension of patching zone as compared to the control beam (without patching). Based on the load-deflection observation of the beam under a four-point bending loading, it is confirmed that the flexural behaviour of the patched reinforced concrete beam is similar to that of control beam at a loading up to about peak load. After this load the patched reinforced concrete beam tends to behave more ductile. The patched reinforced concrete beam show less cracking density compared to control concrete.

The purpose of this research is to investigate the influence of the freeze-thaw cycles on the flexural behavior of reinforced concrete members. The variation of the concrete stress-strain relationship due to frozen-thawed deterioration was considered. The temperature distribution was calculated based on the heat conduction theory, and the damaged region affected by freeze-thaw cycles was determined. By using Reponse-2000 program, the flexural behaviour of a reinforced concrete slab was analyzed and predicted. The analytical results show that with increase of number of freeze-thaw cycles, the yield moment, the ultimate moment and the curvature ductility decreased, while the relative depth of neutral axis and the midspan deflection increased.
