Field Tests on Micropiles Under Dynamic Lateral Loading

Procedia Engineering, 2016
AbstractMicropiles are increasingly used as foundation support of new buildings in seismic areas as well as for the seismic retrofitting of structures that have experienced seismic damage. Hence, it is essential to enhance the knowledge of the dynamic behavior of micropiles under horizontal loading.
