 Question Submitted By :: Civil-Engineering
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
Minimum reinforcement
The mild steel reinforcement in either direction in slabs
shall not be less than 0.15 percent of the total crosssectional
area. However, this value can be reduced to
0.12 percent when high strength deformed bars or
welded wire fabric are used.

Longitudinal reinforcement
The cross-sectional area of longitudinal
reinforcement, shall be not less than 0.8 percent
nor more than 6 percent of the gross crosssectional
area of the column.

NOTE - The use of 6 percent reinforcement may involve
practical diffkulties in placing and compacting of concrete;
hence lower percentage is recommended. Where bars from
the columns below have to be lapped with those in the
column under consideration, the percentage of steel shall
usually not exceed 4 percent.
