2. A concrete slab of uniform thickness is continuous for six spans and is supported by 12-inch-wide concrete beams at 10 ft o.c. The following loads are applied to the slab: DL 100 psf (includes self-weight) and LL = 50 psf Determine all moments and shears. = -10 ft- -10 ft- -10 ft- -10 ft- -10 ft- -10 ft- 12 in. (TYP.)

The concrete post is reinforced axially with four symmetrically placed steel bars, each of cross-sectional area 900 mm2. Compute the stress in each material when the 1000-kN axial load is applied. The moduli of elasticity are 200 GPa for steel and 14 GPa for concrete. Compatibiltiy Equation . Ust Bearing |1000 kN plate Steel- Concrete 300 mm 300 mm Section a-a

The simply supported I-beam shown in cross-section and elevation is to carry a uniform service live load totalling 8 kN/m over 12m span, in addition to its own weight. The beam will be pretensioned using multiple seven-wire strands, eccentricity is 130mm and constant. The 28-day compressive strength of concrete is 40 Mpa. Calculate deflections

"Q1.16-.A rectangular beam has dimensions of 270 mm by 670 mm with an effective depth of 620 mm and is reinforced with 5- 20 mm ø. Concrete cover is 50 mm. The concrete cylinder strength f'c = 30.7 MPa and the tensile strength in bending is the modulus of rupture. The yield point of the steel is 449.5 MPa. The beam carries a bending moment of 67 kN-m. Use transformed section method to answer the following: (1) Compute the concrete compression stress at the top, (2) Compute the concrete tension stress at the bottom, (3) Compute the stress in the steel. (4) Assess the adequacy of the beam design." Use the editor to format your answer width, b ... effective depth, d total depth, h
