![]() ![]() ![]() VU QUBE 2000 CODENow, 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. VU QUBE 2000 TRIALSelect trial web-steel area based on standard stirrup sizes ranges from NO.10 to NO.16.If step 5 is met, compute shear force (V s) that should be resisted by stirrups, use Equation 1.The design of beams for shear should be based on the following relation: 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.This short shifter will accept the standard GMH/GM gear knob only. NOTE 2 – CUBE Speed gear knob is not suitable for this shifter. CUBE Speed have high quality bronze bushes which are much better quality than the factory bushing NOTE 1 – It is highly recommended to change the shifter cup bushing when installing a new shifter as the factory plastic bushes are often broken or worn and will give a very vague sloppy shift. Can be easily installed by enthusiasts with good mechanical knowledge and hand tools. Comes with installation instructions and all hardware as pictured.No difficulty in selecting reverse and 6th as found in some other short shifters.Eliminates bridge and pick up which rattles and binds on the factory shifter.Virtually eliminates the chance of missing third gear.Prevent expensive gearbox damage from over shifting through use of positive shift stops.Shifter throw is reduced by 40%, which equals quicker shifts! The CUBE Speed Commodore T56 short shifter (Classic) is possibly the best improvement you could ever make to your car! ![]()
