SUGGESTING DEFLECTION EXPRESSIONS FOR RC BEAMS
Journal Title: International Journal of Civil Engineering and Technology - Year 2019, Vol 10, Issue 3
Abstract
This experimental work aims at presenting load-deflection expressions for the concrete beams that reinforced with three different reinforcement ratios of ACI 318- 14, which are minimum, maximum and the average of them. Three groups of beams were cast, each group contained three beam specimens. Three types of loading are used, 1-concentrated force, 2-concentrated forces and partial uniformly distributed load. It is also seen that, when reinforcing ratio increases from minimum to maximum, in case of 1-concentrated force, ultimate capacity increases by about 280% and deflection decreases by about 33%, respectively. Whereas, in case of 2- concentrated forces, ultimate capacity increases by about 258% and deflection decreases by about 50%, respectively. Finally, in case of uniformly distributed load, ultimate capacity increases by about 289% and deflection decreases by about 28%, respectively.
