uation 1: A concrete overhang beam with the section shown is to support a 150 mm thick concrete slab with a tributary width of 2.70 m. The beam also supports a 3.20 m height of 100 mm thick concrete partition wall. Unit weight of concrete is taken to be 24 kN/m³. Determine the dead load in kN per meter length of beam and determine the maximum fiber stresses (tensile & compressive) due to the imposed dead loads. Draw the complete V&M diagrams. -wall 300 mm

1.2m 10 cm O 7cm -7cm O This concrete beam has four A-35 steel rods of one centimeter diameter and a square cross section. It experiences a compressive axial load of 200kN. You must calculate the stresses developed in the two components in the figure.

Concrete beam.

A concrete floor slab 100 mm thick is cast monolithic with concrete beams 2.0 m on centers. The beams have a span of 4.0 m, web width of 250 mm and overall depth of 500 mm. The tensile reinforcement consists of 6 - ø20 mm bars in two rows with 25 mm vertical clear spacing. Use material strength f'c = 21 MPa and fy = 415 MPa. Calculate the following considering a T-geometry: Effective flange width of an interior beam in mm = _______ Depth of uniform stress block at ultimate stage in mm to the neares whole number = _______ Tensile steel strain compatible with concrete strain of 0.003 in 3 decimal places = __________
