DFI has published a new research report, Design Considerations for Bonded Micropile-to-Structure Connections, authored by Jesús Gómez, Ph.D., P.E., BC.GE, GEI Consultants.
This report focuses on developing the basis for a design or verification method of bonded micropile-to-existing concrete footing connections using simple design steps. The method allows designers to assess the available capacity of a proposed micropile-to-existing footing connection constructed by direct bonding of the micropile to the footing. This effort was funded through DFI’s Committee Project Fund and endorsed by the joint DFI-ADSC Micropile Committee.
“This paper is a culmination of Dr. Gomez’s dedication and hard work for an important part of micropile design for retrofits and existing foundations,” says Dennis Ambio, Apex Geotech Solutions and DFI-ADSC Micropile Committee co-chair. “We expect that his findings and research lead to achievable constructability results and answer often asked questions surrounding designs for bonded connections with existing footings.”
