The beam shown below is a cross section of a beam for a 4-storey commercial building. Due to limited head room, the dimensions are limited to 250mmx360mm which is reinforced at the top by 2-16mm o bars and 3-25mm o bars at the bottom. Steel covering for both top and bottom bars are 60mm from the center of the bars. If the beam carries a super imposed load of 860kg/m besides its own weight, determine the actual stresses of concrete and steel in tension and compression if n=15, and has a simple span of 6meters

Concept explainers

Members with compression and bending

Compression members are structural elements that carry compressive axial force. They are the vertical members of a building that support beams and their design, which is governed by buckling and strength. Columns are known as struct or compression members, which are subjected to compressive forces. These members provide stiffness to the building and avoid any imperfection regarding the transfer of axial load. For instance, webs in a truss, braces in a framed structure, tiers, and so on.

Question

The beam shown below is a cross section of a beam for a 4-storey commercial building. Due to
limited head room, the dimensions are limited to 250mmx360mm which is reinforced at the top by
2-16mm o bars and 3-25mm o bars at the bottom. Steel covering for both top and bottom bars are
60mm from the center of the bars. If the beam carries a super imposed load of 860kg/m besides its
own weight, determine the actual stresses of concrete and steel in tension and compression if
n=15, and has a simple span of 6meters
