Calculate the design strength of the middle beam. The section is a simple span of 8m. fc' 24 MPa and fy = 325 MPa. It is a monolithic slab with supporting beams. Center %3D to center spacing between beams are 1.5 m. Dimensions: Flange thickness is 75mm; web width is 400mm; top to bottom height of 650mm. SITUATION I: Reinforced 7 - 28mm diameter in two layers with bottom layer with 5 steel bar to the edge of concrete is 70mm at the center, and bottom layer to the top layer is 65mm at the center. SITUATION II: Reinforced 12 - 28mm diameter in three layers with bottom layer with 5 steel bar to the edge of concrete is 70mm at the center, bottom layer to middle layer with 5 steel bars is 65mm at the center and bottom layer to the top layer with two bars is 60mm at the center. Solve for the following 1. Effective flange width 2. Analysis procedures 3. Check if the section adheres with the code by steel ratio 4. Check if the section adheres with the code by strain limit 5. Moment Capacity of the beam

Design criteria for structural loading

The different loads such as loads due to self-weight (dead load) and external loads such as live load, wind loads, seismic load, snow load, and other loads and load combinations that influence the design of a building are called structural loading. The nature of the applied load differs from changes in the location, design, and type of materials used. The design criteria require that structures must be designed and constructed to be able to withstand all load types that are expected to act upon the structure and render its usage for the designated purpose. The structural members such as beams, slabs, columns, and foundations help the structure to withstand the applied load. There are different institutes such as ASCE and ACI that provide building design codes to assure minimum safety requirements and quality of the structures.
