Concept explainers

Load and resistance factor design

Load and resistance factors design (LRFD), also known as Limit state design (LSD), refers to the design method used in building engineering. A boundary condition is a condition of a structure where it can no longer meet the relevant design requirements. The condition may refer to the load level or other actions on the structure, while the terms refer to the integrity of the structure, suitability for use, durability, or other design requirements. A structure designed for LRFD is limited to keeping track of all possible actions during its design time and is always ready for use, with the appropriate level of reliability in each boundary condition. LRFD-based construction codes clearly define the appropriate levels of reliability in their instructions.

20 A rectangular pile (0.75 x 0.93 m.) is driven in a clayey soil arrangement composed of two different layers. First layer has a height of 5 m., cohesion of 53 kPa, friction factor of 0.88. Second layer has a height of 8 m., cohesion of 78 kPa, and friction factor of 0.84. Compute the allowable load that the pile can carry if the factor of safety is 2.17. Round off to two decimal places.
Check the total settlement of a group of pile as shown in Figure 1. The total allowable settlement is set not exceed 3% of the pile diameter and the overconsolidated ratio (OCR) of the clay is more than 1. The groundwater table is located 15m beneath the ground level. The diameter of the pile, b is 0.5m and the spacing between piles, s is 2m.The pile group is subjected to foundation load of 5425kN. The laboratory testing data for the soil samples taken are as follows: At 5m, eo = 0.55, Cc = 0.32, C; = 0.09, o'o = 150kN/m?

Two different single acting hammers are being considered for an open- ended pipe pile. Hammer A has a ram weight of 30 kN and a stroke of 3 m. Hammer B has a ram weight of 15 kN and stroke of 5 m. Both hammers use similar appurtenances. Which hammer will deliver the most energy to the pile? Which hammer will generate the highest stresses in the pile?

A square concrete pile of 10 m length is driven into a deep layer of uniform homogeneous clay. The average unconfined compressive strength of the clay, determined through laboratory tests on undisturbed samples extracted from the clay layer, is 100 kPa. If the ultimate compressive load capacity of the driven pile is 632 kN, the required width of the pile is mm. (in integer) (Bearing capacity factor Nc = 9; adhesion factor a = 0.7)
