Schedule of Beams

The document provides details on the schedule of beams including their dimensions, longitudinal and transverse reinforcement at supports and midspans. Beams include grade beams, floor beams and one composite floor beam. Reinforcement consists of top and bottom round steel bars of 16mm diameter. Stirrups are 10mm round steel bars spaced at varying intervals along the beams.
