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.

Design a rectangular reinforced concrete beam to resist service moments of 120 kNm from dead loads and 110 kNm from live loads. The beam dimension are (b x d) 0.25m x 0.6m. Assume fck = 25 N/mm2 and fyk = 500 N/mm2.
An axially loaded tied column must sustain the following service loads: Total Dead Load = 1,000 kN Live Load = 1,600 kN Required Strength, U = 1.2D + 1.6L Reduction Factor = 0.65 Concrete f’c = 28 MPa Steel fy = 420 MPa Determine the required number of vertical bars to be distributed equally on all sides of the column if the column is 500 mm square using bar diameter = 20 mm. 8 4 12 16
The dimensions for a reinforced concrete beam are given as: b = 300mm d = 400mm d’ = 75mm It is to be designed for a service dead load moment of 30kN-m and a service live load moment of 40kN-m. Suppose f’c = 21MPa and fy = 276MPa, how many 20-mm bars are required to reinforced the beam in terms of steel area?
From load analysis, the following are the factored design forces result: Mu = 440 KN-m, Vu = 280 KN. The beam has a width of 400 mm and a total depth of 500 mm.

Normal weight concrete. Calculate the required area of compression reinforcement in mm2 due to the factored moment, Mu. Express your answer in two decimal places.
A square tied column is 430 mm x 430 mm with 8- 28 mm Grade 415 bars. The lateral ties are 10 mm diameter bars with 40 mm concrete cover. If the unsupported length is 2.50 m and Ku = 1.0, what is the safe ultimate load on the column based on the 2001 NSCP? f'c = 28 MPa. Moment on the column is neglected.

A rectangular beam has b = 350 mm and d = 430 mm with concrete compressive strength f’c = 30 MPa and steel yield strength fy = 345 Mpa. If compression steel area is required, it will be placed 70 mm from its cg up to extreme fiber. Calculate the following: a) Required steel area if the beam is subjected to dead load moment of 30 kN-m and live load moment of 25 kN-m b) If the beam has 5-16 mm diameter rebars, determine if it is compression-controlled, transition or tension-controlled. c) Required tension steel area at factored moment of 400 kN-m.
A 6-m clear-span simply supported beam carries a uniform dead load of 47.5 kN/m and a live load of 25 kN/m. The dimensions of the beam section are b = 350 mm, d = 550 mm. The beam is reinforced with four bars 25mm diameter in one row. It is required to design the necessary shear reinforcement. Given: f’c = 28 MPa and fy = 280 MPa.
