What is a BBS?Find out the cutting length for a 300*300 column with 40 mm cover?

Answer Posted / amit sharma

300*300 10dia
Cover deduction from sides 40*2=80
1. Ring size = 300-80 = 220
Sides 4*220=880
2.For hook take 10*d=10*10*2 = 200
Now deduction for bend. so below 16 dia its 1.5d or above 2d so
5*1.5*10 = 75
Now = 880+200+75 =1155
Now every one forget one thing when we bend the ring around the bar suppose that bar is 32 dia so dia/2 is also include at every bend of the ring.

In foundation design, while we do the base pressure check, we normally check if the attained pressure value is less than the GROSS BEARING CAPACITY of the soil which is the sum of net bearing capacity of soil and the overburden pressure. Actually, the overburden pressure acts against the net bearing capacity of the soil and I feel that we are actually increasing the bearing capacity value and doing the check. I feel that this is NOT right. Please clarify on this.

A doubly reinforced concrete beam is 25 cm wide and 50cm deep to the centre of tension reinforcement. The centre of compression is steel is 5cm from the compression edge. The areas of the compression and the tension steel are 10.16cm2 and 12.56 cm2 if m=18 and the bending moment at the section is 7,000,000 N-cm. Calculate the stress in concrete and steel.
