PART B 2. (a) What is the criterion of failure of reinforced concrete flexural elements? What distribution of compressive stress is normally assumed across the compression zone of a reinforced concrete beam, and how does this compare to the actual stress distribution? (b) Obtain the ultimate moment of resistance of the beam section indicated in Figure 2, if the grade of the concrete used in the section is 35N/mm?, and the yield stress of the steel is 500N/m2 s) 750 6T20 350 ST25 6T25 200 Figure 2
The cantilever-reinforced concrete beam shown in Figure 1 is subjected to a uniform load (including beam weight) and a concentrated load at the free end of the beam. 1.) Determine the cracking moment capacity, . 2.) Calculate the maximum unfactored applied moment and state whether the concrete beam has cracked under the applied loads. 3.) Compute the maximum compressive stress of concrete at the bottom of the beam and the maximum tensile stress at the centroid of the steel bars. Can you work it out and show all the steps on paper, and any other helpful little steps to explain the process.
Compression controlled failure in reinforced concrete beams as per NSCP 2015 is when the tensile strain of rebars is less than the yield strain. True False
The concept of ‘barreling’ was discussed as it related to the standard testing of concrete cylinders. In addition to be observed in concrete this is observed in other materials. What is meant by ba rreling (i.e., the bulging of the center portion of the cylinder during the test) and how would it influence the results of a compressive test?
A 150mm diameter cylindrical concrete specimen was tested for splitting tensile strength. The splitting tensile stress at failure is 4.14 MPa, what is the applied force in kN? The sample length is 300mm
A center point loading is used to test concrete for flexure. The sample is 150mm x 150mm and has a clear span of 600mm. The sample failed when the load applied is 100,000N. What is the flexure stress at failure in MPa?
The tensile test has been performed on a 50 mm long steel tube having 18 mm external diameter and 12 mm internal diameter. The axial load of 2 kN produced a stretch of 3.36 x 10-³ mm and a lateral contraction of the outer diameter of 3.62 x 104 mm.

A concrete cylinder sample has a diameter of 4 inches and a height of 6 inches. The maximum load carried by the sample after its failure is 275 KN. Determine the compressive strength of the sample in psi. (use 1lbf = 4.45 N, round-up your answer to the nearest whole number that is divisible by 5, no need for unit)
A 150mm diameter cylindrical concrete specimen was tested for splitting tensile strength. The Sample failed when the applied force was 120 kN. What is the splitting tensile stress at failure in MPa? The sample length is 300mm
Q1- A concrete cylindrical sample 14.8 cm in diameter and 30.5 cm long is subjected to compression. The sample failed under a compressive load of 698.4 kN and the stress-strain relation showed a complete elastic behavior. If the deformation at 60% of the strength is 0.21 mm, determine the: i- Strain at failure in percent. ii- Young's Modulus of Elasticity in GPa. iii-Length of the sample at half strength in mm. iv- Strain at three quarters of the strength in percent.
In the ultrasound test performed in the axial direction on a 75x75x285 mm edge concrete prism weighing 850 g, it was measured that the sound passed through the 285 mm length in 78 microseconds. It was determined that a sample made of the aforementioned concrete made a unit shortening of 7.4x10-4 under 200 kgf/cm2 tension. The f - ε behavior of concrete is represented by the SMITH-YOUNG function. Calculate the possible compressive strength of the concrete in question. (Take the value of e as 2.71.)
