Advantages of performing strain-based analysis for pile design

Posted on
 

 Per the current state of practice, a pile design is typically completed by checking the following design items: Static settlement which includes elastic compression of pile, immediate and consolidation settlements of soil; Structural and geotechnical bearing capacity of pile in static and seismic conditions; Seismic settlement under downdrag forces induced by the surrounding soil during… Read More
