Reinforced concrete beams 290 mm wide and 536 mm deep are spaced 2.59 m on centers. Columns are 389 x 389 mm square. The beams support a slab 126 mm thick carrying a superimposed dead load of 5.18 kPa. Concrete weighs 24 kN/m³. No live load reduction should be applied on this problem. Use main bar diameter = 20mm and stirrups diameter = 10 mm spaced @ 115 mm. Use fc = 22.25 MPa and fy = 278 MPa Use the following dimensions: s = 2.59 meter L = 8.65 meter Calculate the maximum service live load in kPa that can be carried by beam DE based on shear design criteria.
