• A two-span continuous one-way slab with span length of 4.3 meters is integral with its beam supports which are 300 mm wide with spacing 2m on center. The slab carries a factored load of 27000 Pa. f'c = 21Mpa and fy = 275 Mpa. a. Determine the minimum depth of slab (mm). b. Compute the positive and negative factored bending moments (KN-m). c. Calculate the spacing of 10mm main bars (mm). C. d. Find the spacing of 10mm temperature bars (mm).

A cantilever beam with length of 3.2 m is reinforced with As=5720 mm^2 tension reinforcement and compression reinforcement A's =1905 mm^2 placed at 60 mm from extreme compression fiber. The effective depth is 550 mm and width of 400 mm. Use f'c=35 MPa and fy=415 MPa. 1. Calculate the magnitude of the neutral axis. 2. Determine the compressive force of the section. 3. Determine the safe concentrated live load that can be placed at the free end if the beam carries a total ultimate uniform load of 35 kN/m.
