Relationship Between Number and Size of Required Steel Reinforcement to Beam Dimension of Standard Public School in Malaysia

Overdesign of structural components may result in unnecessary wastage of materials and contribute towards higher construction cost. One structural component most frequently overdesigned is the Reinforced Concrete beam where the amount of steel reinforcements used are way much higher than required to cater for intended design loading. This paper scrutinizes the relationship between the size of beam towards number and size of the required steel bar of the general public school, the number and size of the tension reinforcement bar needed due to the variation of beam size in each ratio based on the general public school and the number and size of the shear reinforcement bar needed due to the variation of beam size in each ratio based on the general public school to become the guideline for the beam design.
