Q4. A post-tension concrete beam, 8m length of a rectangular section, 100 mm wide and 300 mm deep, is pre-stressed by five wires of 7 mm diameter located at an eccentricity of 50 mm. The initial stress in the wires being 1200 N/mm2. The modulus of elasticity of steel and concrete are 210000 and 35000 N/mm, respectively. Estimate the percentage loss of stress in steel due to creep of concrete, if the beam carrying a dead load of 3kN/m.

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.
