Flexural Behavior Of Reinforced Light Weight Concrete Beams Provided With Tension Bar Splices
El-sayed Mohamed Anter Abdallah;
Abstract
In order to examine the behavior of tension lap splice in light weight reinforced concrete beams and its variable factors an experimental program has been conducted.
The program included the testing of eight reinforced concrete beams under two equal concentrated loads applied at the middle third with the lap splices within this part of the beam, where the shear is zero.
An experimental and theoretical work has been conducted to investigate the effect of splices of reinforced light weight concrete, in the general flexural behavior of concrete beams. The present work deals with beams having at the location of maximum moments with different percentages of reinforced bar, (25% splices & 50%splices and 100% splices), effect the percentage of stirrups (5@8/m, no stirrups and 10@10/m) and effect of bar diameter, (bar 12 and bar 16 mm)
The experimental work consisted of three testing groups of beams. These groups percentage of splices bar, percentage of stirrups and bar diameter respectively.
Each group consist 3 beams and 2 beams reference without splices one of beam reference normal weight concrete and other beam light weight concrete.
The finite element method was conducted to verify and confirm the experimental results. The finite element analysis of the present work is capable of considering the yielding of reinforcement.
Finally the experimental and theoretical results from the finite element analysis, some recommendation for both designer and researchers which work in this area.
