Static resistance loading of reinforced concrete beams using normal and steel fiber self-compact concrete, with loading applied at the one – third of the beam (four points) was studied. The reinforced concrete beams have been designed under static load according to ACI-318R-2014 [1]. The static loading consists of dead load and residential live load based on ASCE-07-2010 [2].as the beam a part from residential building that scaled down and modeled to not at full scale but as like the traditional experimental test. A three-dimensional finite element models by ANSYS15.0 software [3], have been established to provide a numerical solution as an alternative approach to the experimental models, with some acceptable accuracy. Experimental tests for normal, self – compact and with and without steel fiber concrete to specify compressive strength, tensile strength, and modulus of elasticity presented. Modeling analysis as simply supported beams as approximate situation of beam that was performed to evaluate the performance of ordinary, self-compact and steel fiber self-compact concrete beams under static loading.

This research aims to evaluate of using the glass fiber on the properties of fresh and hardened self compacting concrete (SCC).The work involves four mixes , the mix proportion of these mixes is(1:1.75:2),and water cement ratio is(0.4), superplasticizer of ( 5 ) % of cement content, limestone powder of (100Kg /m3) ,and glass fiber (0,1,3,5)% of mixes volume respectively .
Slumpflow, L-Box and V-funnel tests are using to determine the workability of all mixes, the values of slump flow are (710,680,655,615)mm, the values of t50cm are (2,3,3,5) second, the blocking ratio (H2/H1) values are (0.93, 0.87, 0.86, 0.82) and the flow time through the V-funnel are (6, 9, 11, 12) seconds respectively, the mechanical properties studied in this work are compressive strength with average value of six spacements are (28.6,29.2,29.8,31.5) , (47.3,48.7,51.3,54.7)N/mm2 of (7,28) day ages respectively , and splitting tensile strength with average values of six spacements are (4.1, 4.3,4.6,5.1) , (5.2,5.8,6.1,6.5)N/mm2 of (28,56) days ages respectively .
Flexural strength (Modulus Of Rupture)(MOR) was tested with average values of three spacements are (4.1,4.3,4.6,5.1) , (5.2,5.8,6.1,6.5)N/mm2 of (28,56) day ages, for glass fiber ratio of (0,1,3,5)% respectively .
