Numerical Analysis of the Bearing Capacity of Thermoactive Piles Under Cyclic Axial Loading
This chapter presents a numerical study of the bearing capacity of thermoactive piles, aiming to ensure the capacity of this type of foundation due to thermal cyclic variations. A section deals with load transfer analysis, to study the response of a pile under a single additional thermal load. Since each year the thermoactive pile undergoes a cycle of temperature variations during the operational time, it is necessary to take into account the cyclic loading effects. A 3D numerical model of a thermoactive pile in cohesionless soil mass is then performed using a constitutive interface behavior law under cyclic loading. The constitutive law of soil—pile interface under cyclic loading, the Modjoin law, can reproduce kinematic hardening under cyclic loads and thus control the cyclic degradation effects. The influences of different end‐connections at the pile—upper structure interface as well as the different service loads applied are discussed.
