Techniques, Materials, and Design Considerations for Strengthening & Repair of Existing Concrete Structures
Nate Poen - Structural Technologies
There are many factors that create the need for strengthening. They include construction and design errors, increase in live load, new code requirements, low concrete strength, voids created during concrete placement, new penetrations and prevention of progressive collapse from blast loads. This presentation will describe the design strategies, different techniques, materials and design concepts used for upgrading concrete structures which will also be illustrated through actual case studies including two design by Frank Lloyd Wright – Fallingwater and the Guggneheim.
Nate Poen is a Manager, Strengthening Solutions for Structural Technologies. His responsibilities are to aid the contracting and structural engineering communities to formulate value engineered solutions to strengthen existing concrete structures. Structural Technologies primarily works on strengthening existing structures on adaptive reuse or renovation projects and also repairs design/construction defects on ground up jobsites. Prior to his position at Structural Technologies, Nate was a Territory Manager at EFCO Corp. where he aided clients to find engineered concrete formwork solutions in the heavy civil/bridge market. Nate is a Civil Engineering graduate of Iowa State University.
