10.1 Introduction What's piles-Piles are structual members of timber, concrete,and/or steel that are used to transmit surface loads to lower levels in the soil mass. How pile transmit loads-by skin (or side)friction (resistance)and point (or end)resistance. Skin (or side)friction (resistance)-vertical distribution of the load along the pile shaft Point (or end)resistance-direct application of load to a lower stratum throught the pile point 10.1 Introduction ◼ What’s piles-Piles are structual members of timber, concrete, and/or steel that are used to transmit surface loads to lower levels in the soil mass. ◼ How pile transmit loads-by skin (or side) friction (resistance) and point (or end) resistance. ◼ Skin (or side) friction (resistance)-vertical distribution of the load along the pile shaft ◼ Point (or end) resistance-direct application of load to a lower stratum throught the pile point
