A machine foundation is supported by four prestressed concrete plies driven to bedrock. The length of each pile is 24 m, and they are 0.3 mx 0.3 m in cross section. The weight of the machine and the foundation is 1360 kN. Given: unit weight of concrete = 24 kN/m¹ and the modulus of elasticity of the concrete used for the piles = 24.5 x 106 kPa. Determine the natural frequency of the pile foundation system.

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.
