However, the ACI code specifies that minimum reinforcement (i.e maximum spacing) should be provided for such area. Theoretically, if concrete shear design strength is greater than shear force, then no stirrup is required. Now, distribute stirrups according to ACI code requirements: V s,required=187.22 KN required spacing which 140 mm V s,required= V u, at distance (d)- V c= 335.65-148.426= 187.22 KN, Stirrups should be designed to withstand this amount of shear force which is in excess of shear strength of concrete. Since V u, at distance (d)=335.65 KN> V c= 148.426 KN, Therefore shear reinforcement is required. So, shear force at a critical section of the beam is computed as follow: However, for simply supported beam, the location of the critical section for shear design is at distance (d), where (d) is effective depth. Shear force at the face of support is 411 KN. Material properties: fc′=28 MPa, and fyt=420 MPa Solution:Ĭompute shear force on the beam by using equation or draw shear diagram: Design the beam for shear using vertical U stirrups. It is reinforced with 4914 m 2 of tensile steel, which continues an interrupted into the supports. Finally, draw the design beam with longitudinal and shear reinforcement.Ī simply supported rectangular beam 400 mm wide having an effective depth of 550 mm carried a total factored load of 137 KN/m on a 6 m clear span.If Vs is greater than 0.33fc’^0.5bwd, then these maximum spacing shall be halved.The required spacing shall be equal or less than maximum spacing calculated using Equation 6.And, place stirrups accordingly in groups of varying spacing. However, over long spans, it is more economical to compute the spacing required at several sections.Distribute stirrups uniformly over short span beams.Find spacing for the stirrup, use Equation 3 or Equation 4.Multiply shear reinforcement area by a number of stirrup legs to calculate shear reinforcement area.

One from shear reinforcement consisting of hoops or stirrups, which may be placed vertically or inclined at some angle with horizontal.Īnother is in the form of web reinforcement that may consist of flexural reinforcement which can be bent diagonally upward (where it is no longer needed to resist bending) to reinforce the web.įigure-3: Location of Critical Section for Shear Design ACI Code Provision for Shear Design of RC Beam 1. When the concrete cross-section has an insufficient area to maintain shear stresses below permissible values, additional resistance to shear may be provided in two ways. Shear compression failure, where the beam has a small shear span/depth ratio of the magnitude of 1-2.5 for concentrated loading and less than 5 for distributed loading.Diagonal tension failure, where the strength of the beam in diagonal tension is lower than its strength in flexure.Flexural failure in which cracks are mainly vertical in the middle third of the beam span.Procedure for the Shear design of RC Beamįundamentally, three modes of failure or their combination occur:.ACI Code Provision for Shear Design of RC Beam.Location of Critical Section for Shear Design.
