A T-beam (internal) for a floor system has a slab thickness of 100mm and a total depth of 550mm. It has a web thickness of 300mm. The T-beam is casted monolithically with the slab. The beam has a simple span of 6.0m with a spacing of 2.4m center to center. The beam carries a live load moment of 163 kN.m and a dead load moment of 84 kN.m. Assume f’c = 20.7 MPa and fy = 413.7 MPa. Assume steel covering to the centroid of the reinforcement is 65mm. Determine the following and discuss your solution: (a) Effective width of flange (b) Depth of compression block (c) Steel area required

Question
A T-beam (internal) for a floor system has a slab thickness of 100mm and a total depth of 550mm. It has
a web thickness of 300mm. The T-beam is casted monolithically with the slab. The beam has a simple span
of 6.0m with a spacing of 2.4m center to center. The beam carries a live load moment of 163 kN.m and a
dead load moment of 84 kN.m. Assume f’c = 20.7 MPa and fy = 413.7 MPa. Assume steel covering to the
centroid of the reinforcement is 65mm. Determine the following and discuss your solution:
(a) Effective width of flange
(b) Depth of compression block
(c) Steel area required
