QI) Based on only deflection requirements, determine the span length of a simply supported one-way slab with a thickness of 150 mm if the total deflection after 5 years equals 32 mm. The slab is loaded with 4 kN/m service dead load and 2 kNim service live load. The slab is supporting nonstructural constructions that are likely to be damaged by large deflection. Assume that the total service moment is less than the cracking moment and use E= 23500 MPa and f, 420 MPa.

Question
Q1) Based on only deflection requirements, determine the span length of a simply supported one-way slab with
a thickness of 150 mm if the total deflection after 5 years equals 32 mm. The slab is loaded with 4 kN/n service
dead load and 2 kN/m service live load. The slab is supporting nonstructural constructions that are likely to be
damaged by large deflection. Assume that the total service moment is less than the cracking moment and use
E = 23500 MPa and f,= 420 MPa.
Q2) Check the cracking control requirements according to the ACI 318-95 and the ACI 318-14 for a concrete
beam that has a width of 350 mm. The beam is reinforced with 6020 (one row) and 10 mm diameter stimups.
Use f, = 420 MPa.
