The continuous beam shown in Fig. 1 is part of a beam-and-slab floor system of an office building and is typical of a series of beams spaced at 4 m intervals. In addition to the dead load, the live load on the floor is 3 kPa. Using f'c = 32MPa, N32 bars for main reinforcement, a) Find the maximum positive and negative moments using the AS3600 simplified method. b) Design the beam cross-section for the maximum amount of tensile steel...

I just need help with (I). I can not seem to find the self-weight
equation to add to my dead load.
1. A reinforced slab built integrally with beam consists of four spans (8' 6" on- center). The clear span of the slab is 7' 6" for all spans including the end span. The service live load is 160 psf and the service dead load is 30 psf (excluding self-weight). Given: f'.= 4,000 psi, normal weight concrete, fy= 60,000 psi....

Name beam shown in Figure is a W16 x 31 of A36 steel. It supports a reinforced concrete floor slab that provides continuous lateral support of the compression flange The service dead load is 450 lb/ft. This load is superimposed on the beam: it does n include the weight of the beam itself. The service live load is 550 lb/ft. Does this bean have adequate moment strength? (25 430 550
5. Determine the mid-span short-term deflection of a simply supported beam with the section shown in Figure Q5. Design data: Concrete strength: fcu 30 MPa.

Need help with E and F please.
3. The beam shown in the figure below is carrying superimposed dead load of 25 kN/m and use and occupancy load of 45 kN/m. For preliminary analysis, assume a self weight of 10 kN/m. We are required to find the maximum positive (tension at the bottom) and negative (tension at the top) moments due to the factored loads, and then design the beam CIV E 374-RC-Lab 3 Fall 2018 (a) Determine the maximum...

A reinforced concrete cantilevered beam with a span of 5 m extends from the wall, as shown in the figure below. The beam has a rectangular cross-section and supports a uniform dead load (DL) of 15 kN/m (excluding the self-weight) and a uniform live load (LL) of 25 kN/m. The beam width is restricted to 400 mm.
