Analysis of barrette foundations subjected to mechanical and thermal loads

Lyesse Laloui, Alessandro Francesco Rotta Loria

In recent years, there has been increasing interest in the use of rectangular barrette foundations for the structural support and energy supply of tall buildings when circular piles become inefficient or uneconomical. In such applications, so-called energy ...
