CFRP SHEAR STRENGTHENING PERFORMANCE OF VARYING HOLLOWNESS RATIO REINFORCED SELF COMPACTING CONCRETE BOX T-BEAMS
Journal Title: International Journal of Electronics, Communication & Instrumentation Engineering Research and Development (IJECIERD) - Year 2017, Vol 7, Issue 3
Abstract
There is a few interesting research about reinforced concrete box beams under the effect of shear loads; therefore, a shear failure mechanism is not understood well. In the present paper, the effect of hollowness ratio variation and strengthening by CFRP strips on the structural performance of reinforced self-compacting concrete (SCC) box beams, subjected to shear loads is studied. Eighteen reinforced SCC beam specimens have a dimension of (1500x200x300mm) for length; width and height, respectively were poured and tested. The tested beams were divided into three groups based on the top flange dimensions. For each group, three variables were adopted; section, type (box or solid), hollowness ratio and strengthening by CFRP strips. Experimental results show that the increasing of the webs thickness from (50mm) to (62.5mm, 75mm and cast without hollow) ultimately result in capacity increase of about (11%, 18% and 40%), (6%, 9% and 17%) and (10%, 18% and 37%) for rectangular, T-beams with (300 mm) top flange and T-beams with (400 mm) top flange, respectively. Increasing in top flange width from (200mm) to (300mm) led to an increase in ultimate capacity about (30%, 24%, 20% and 10%) in comparison to its counterpart beams respectively. Increasing of top flange width from 300mm to 400mm led to an increase in the ultimate capacity about (18%, 25%, 27% and 18%) in comparison to its counterpart beams, respectively.
