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.

A three-lane northbound section of interstate (withthe design lane conservatively designed) has rigidpavement (PCC) and was designed with a 10-inch slab,90% reliability, 700 lb/in2 concrete modulus of rupture,4.5 million lb/in2 modulus of elasticity, 3.0 load transfercoefficient, and an overall standard deviation of 0.35.The initial PSI is 4.6 and the TSI is 2.5. The CBR is 2with a drainage coefficient of 1.0. The road wasdesigned exclusively for trucks that have one 24-kiptandem axle and one 12-kip single axle. It is knownfrom weigh-in-motion scales that there have been 13million 18-kip–equivalent single-axle loads in the entirenorthbound direction of this freeway so far. If a sectionof flexible pavement is used to replace a section of thePCC that was removed for utility work, what structuralnumber should be used so that the PCC and flexiblepavements have the same life expectancy (the new lifeof the flexible pavement and the remaining life of thePCC)?
