The rules on iron strength dimensions and standards for building structures are regulated in SNI (Indonesian National Standard). Iron sold in the market also many do not have SNI standard, this can doubt the strength of iron tug.
but this constraint is related when working on the reinforcement of steel in the field work, that is when grafting steel reinforcement. Improper grafting will make the strength of the reinforcing steel low. The reinforcement of steel reinforcement shall be in accordance with the SNI of 40D (40 times the diameter of reinforcement).
each in the iron connection also needs to be given a little bending to iron joints become more solid and increase the tensile strength of the reinforcement. in the drawings of this plan should also be mentioned the details of the connection, bengkokan and dimensions are clear.
below there is an example of a minimum length calculation for steel reinforcement connections as below:
Is known:
Reinforcement diameter = ( Ø 16 mm )
Asked: Minimum reinforcement length ( ........ ? )
Answer:
@aguessI understand another reason why the basic theory for tensile strength and tensile iron steel is based on the regulations of SNI. Please read this source:
