Many techniques have been used in repair and strengthening of
reinforced beam, among which are external steel beams, external
pre- stressing, epoxy injection, additional concrete overlay, external
steel plates, additional longitudinal and transver
se - steel bars.
Fifteen R.C. beams were tested until failure and the deflection,
surface strains, internal steel strains, external steel strains and crack
patterns were measured, the results were analyzed and conclusions
were summarized. Finally, the recommendations were stated with
the needed future work.
Using high strength concrete made a big step in designing and
constructing reinforced concrete structures. In this research, shear
resistance of high strength concrete beams with average resistance
of (65Mpa) and without shear reinforcement was ca
lculated by
making Experimental tests, also we studied the effect of cross
section shape on shear resistance, and measured the deflection in the
middle of the beams then we compared these results with the
mathematical results and with results from other researchers, finally
we developed a relationship to determine shear capacity in high
strength concrete T beams.
This research studies the elements of "story telling" in the
Andalus‘s poetry in " al-Twaef " age in. Some poets tended to display
in their poems some elements of the art of storytelling. They narrated
their adventures and certain incidents that f
aced them. However some
made used of some elements, though in incomplete way. Some did
concentrate on certain elements more than others. This would be the
area the present research aims to explore.
The research will deal with the diverse, relationships that exist
among these elements, and their dependence on each other. This will be
done through the study of some poetical samples. The method will be
analytical that endeavours to explain the structure of the poetical
stories.
