Question
A one-way slab has a rigid support (both fixed) and a span of 4m. The slab is to carry a uniform live load of 3.2 kPa. Assume f’c = 30 MPa and fy = 345 MPa for all bars. Unit weight of concrete is 24 kN/m3 . The slab concrete cover is 25mm. Use 12mmØ main bars and 10mmØ temperature bars. a. 1 pt. Determine the maximum negative moment (kN-m) of the slab per meter strip. b. 1 pt. Determine the spacing (mm) of main bars based on the negative moment slab per meter strip. c. 1 pt. Determine the spacing (mm) of temperature bars of the slab per meter strip.
