BBS OF 2L Rectangular Stirrups In this article, I’m going to discuss, how to calculate the cutting length of a rectangular stirrup. Before proceeding with the calculations, let me introduce you to the components of a Stirrup or a Tie. As you can clearly visualize from the above picture, a rectangular stirrup is bent at 3 of its corners by an angle of 90 degrees, and 2 number of 135-degree bends along with 2 number of hooks given at the 4th corner. Example: Calculate the cutting length of a rectangular…

Reinforcement lapping zone in Beams

Muyeen Mubarak

Lapping zone in Beams: As I have already told you in my previous article, If the span of a structural member needs to be increased beyond the standard length (12m) of the reinforcement bar, then we must increase the length of bars by adding extra steel bars. The most important thing, we can’t add the bars directly from end to end to avoid the risk of steel sliding out of concrete. That’s why we overlap the bars at certain points to allow a smooth transfer of loads from one bar…

Basics of bar bending schedule

Bar bending schedule-Introduction: The Bar Bending Schedule (BBS) depicts the bend shapes and cut lengths of bars according to the structural drawings.  Because bars are bent in different shapes according on the curvature of the member, each member will have its own BBS. Basics of Bar Bending Schedule (BBS) In this article, I will discuss the basics of Bar Bending Schedule, in which I am going to discuss the various sizes of reinforcement bars used. The next topic will be about hooks, in which I will discuss the reasons for providing…

Reinforcement lapping zone in column: The standard length of reinforcement bars is 12 meters, as we all know. If the span of a structural member, such as a beam or column, needs to be increased beyond the usual length of the reinforcement bar, we must also raise the length of steel bars by adding extra reinforcement bars. If the straight bars are added end to end, there is a risk of steel sliding out of concrete, which can be avoided by overlapping the bars. The goal of overlapping of reinforcement…
