3. - Minimum diameter of ties (stirrups) is ¼ the diameter of the larger longitudinal bar diameter but not less than 8 mm . The minimum volume of hoops ( ties or stirrups ) is 0.25 % of the volume of concrete . 4. - Hoops of columns as well as spirals are to be placed also within the depth of the beams ( Fig . 6 ) . 5 Stirrups aid in the retention of primary reinforcement bars and prevent columns from buckling. They are used to secure beams and columns at the right intervals to prevent them from buckling. Additionally, they prevent RCC constructions from collapsing as a result of seismic activity (earthquakes). Stirrups in Constructions In concrete construction reinforcement bars to be used find the cutting length of each bar find the number of stirrups calculation or number of distribution bars calculation if it is a slab find the cutting length of stirrups or extra bars top rods, now calculate cutting length of column cutting length footing depth cover m bar Steps for BBS of Column: Generally, there are five steps for preparing the bar bending schedule of column these five is given below: Find the length of Vertical Bar.
