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.

It is to be supported on a square footing withf′ c = 17 MPa and fy = 420 MPa. The soil has an allowable bearing pressure for bearing cap-acity of 650 kPa (based on LRFD methods) and an allowable bearing stress for settlement of 160 kPa.

Answer Completely
A 300 mm x 400 mm column is to be supported by 419 m thick square footing @its center. Service DL = 620 kN, service LL = 538 kN, CC to bar centroid is 90 mm, fc' 22 MPa and fy = 414 MPa. Consider the weight of the footing and soil to be 14.84% of the dead load. SBC = 212 kPa 300 400 300 Determine the critical ultimate punching shear stress in MPa Note: Present the width (B) in multiples of 100 mm.
An RCC square footing of side length 3 m and uniform effective depth 250 mm is provided for a 300 mm x 300 mm column. The line of action of the vertical compressive load passes through the centroid of the footing as well as of the column. If the magnitude of the load is 380 kN, then the nominal transverse (one way) shear stress in the footing is N/mm2.
