What have you looked for? Building regulations in most countries specify the calculations to use along with safety factors. You also need to supply details of the beam, a 4*4 in pine or steel rsg with a 20” depth @ 10” width? – Solar Mike Nov 13 '18 at 05:06

Hi Mike, Frankly no safety factors seen, to construct pillar 4*4 feet deep and four 16mm and two 12 mm steel rods are used – chethan bhounsley g Nov 13 '18 at 05:36

This question is impossible to answer on this site. You'll need to hire a licensed engineer to look at your particular case. See [this question](https://engineering.stackexchange.com/q/6467/1832) to understand why. – Wasabi Nov 13 '18 at 12:00
