Dear sir, How to calculate the average spacing of ties, if a column having length of 3 m. The spacing of ties in CR (i.e. 1 m) is 125 mm and in NR (i.e. 2 m) is 175 mm. Thanks
Divide the column length into three parts as l/3 or l/4 then the regions closer to joints are subjected to greater moment and torsion hence requires closer spaced stirrups to bind the longitudinal rebars together than at central portion if 2-legged ties is used then area of stirrups = 2*pie*8^/4 =100.53 .. considering the shear requirement from design as 350mm2/m the spacing required = (1000/350)*100.53 = 287.2 mm As per 26.5.3.2 clause of IS 456 the spacing of ties should be less than maximum of least column dimension 16 * dia of smallest longitudinal bar 300 mm
Thanks
Welcome
Why you didn't apply any wund load or seismic load?
lateral load not considered

provide concrete 20 instead of 20000 kn/m2
Yes. I had entered *20 in kn/m2 it should have been 20.000 kn/m2 for M20 grade of concrete* as 1000 kn/m2 = 1 mpa
