As young professionals step into leadership roles, they face different challenges in both practice and academics than those of generations past. In considering these challenges, this paper examines such issues as the structure of engineering education, licensing, collaboration between academics and practitioners, retention, economic impacts, and public awareness. The discussion will provide a roadmap for addressing key challenges facing young professionals within structural engineering and suggest continued areas of discussion for both practitioners and academics to safeguard the success of the next generation of leaders in the field.

Investigation for the Removal of Steel Tie Rods in a Historic Segmental Arch Floor

GMS investigated the removal of the tie rods in the floors of the landmarked Metropolitan Life Tower in New York City. This building was the tallest in the world when it opened in 1909.  The typical floor is constructed of segmental concrete arches supported on steel beams with tie rods perpendicular to the beams below the arches. We evaluated the removal of the rods which resist the thrust of the arches by performing linear and nonlinear 3d finite element analysis of the floor system. We load tested 5 locations in the building in order to confirm that the floor would perform satisfactorily if the tie rods were removed and to verify there would be no detrimental impacts on the adjacent building elements.
