Soil-Structure Interaction: Springs and Things
Presented By: Michael Paquette, P.E., Senior Project Manager, Langan (Philadelphia)
This presentation will discuss the use (and misuse) of springs when modeling soil-structure interaction. Soil and rock are complicated materials to predict the load-deflection response. For simplicity in design, the geotechnical engineer typically provides the structural engineer with an equivalent linear spring to represent the load-deflection response. This simplification can aid in design, but in some cases can produce an unconservative response in the structural model. We will discuss the following:
· How springs are developed for both shallow and deep foundations
· Slab-on-grade vs. mat springs
· Axial and lateral springs for piles
· When and why iteration of spring values is required
· State of practice – how springs are currently used in simplified and complex models
· Behold the future – some thoughts on the recent shift in modeling soil-structure interaction
About Our Speaker:
Mr. Paquette has 17 years of geotechnical experience in New York, New Jersey, Pennsylvania, California, and abroad. His experience includes geotechnical explorations and site evaluations, shallow and deep foundation design, soft clays, karst hazards and sinkhole evaluation, mine evaluation, retaining wall design, excavation support and underpinning, seismic and liquefaction analysis, ground improvement evaluation and design, surcharge and wick drain design, pavement design, and slope stability analysis. Mr. Paquette has worked on a wide range of projects, including school, stadium, hospital, offshore platform, commercial retail development, residential high-rise and low-rise structures, warehouses, park facilities, tunnel, waterfront structures, and wetlands. His experience includes notable projects such as Hudson Yards and the Kingdom Tower.
