Presentations Friday, Oct. 301: Solving the Riddle of Concrete Shear StrengthRobert Frosch, Ph.D, P.E., Purdue University, West Lafayette, Indiana9:00 am - 11:50 am9:00 am - 9:50 am1.0 PDHThe shear strength of structural concrete has been investigated for well over 100 years. While significant progress hasbeen made in the understanding of shear behavior, the advent of alternative reinforcing materials has provided clues thatcan be used to solve this ongoing riddle. This presentation will explore a new theory regarding the resistance of concreteto shear. Using this theory, a simplified design procedure is developed that can be used for the shear design of structuralconcrete members reinforced with either steel or fiber reinforced polymer (FRP) bars. Furthermore, the applicability of thedesign approach to prestressed as well as partially prestressed members will be explored.Robert J. Frosch is a Professor of Civil Engineering at Purdue University. He received his BSE fromTulane University in 1991 and his MSE and Ph.D from the University of Texas at Austin in 1992 and1996, respectively. He is active in both research and teaching specializing in structural engineering.He is a registered Professional Engineer in Indiana and Louisiana.

They develop substantial strength and stiffness,and with proper care in design achieve the ductility and inelastic deformation capacity needed for seismic performance.Gusset plate connections are an integral part of braced frames, since they join the braces to the beams and columns ofthe frames. These connections must develop the resistance of the brace and the frame and accommodate the inelasticdeformations required during seismic loading. This presentation focuses on design methods and inelastic performance ofgusset plate connections. The research work was motivated by seismic design requirements, but the implication of theresearch results has much broader implications for the design of lateral load resisting systems.Charles Roeder is a Professor of Civil Engineering at the University of Washington (UW). He has servedon the faculty for 32 years, and has performed a range of research related to the seismic performance ofsteel and composite structures. He is a member of a number of professional organizations includingASCE, AISC & SEAW.

M.ASCE, Principal, Weingardt Consultants, Denver, CO8:15 pm - 9:15 pm1.0 PDHWith the world's growing dependence on engineering and technology, increasing numbers of public, industry andcommunity leaders need to be well versed in the complexities and nuances of both. The situation, coupled with theinstability of global marketplaces and economies, ever-present infrastructure and environmental concerns, and anexploding world population, demands that honest pragmatic thinkers be in positions of high leadership and authority. Asprofessionals intuitively having such qualities, more engineers than ever before need to step forward and be heard, andget meaningfully involved in helping set public direction and policy. Discussed are why it's good business for structural'sto do that -- and why it behooves them to “run things and not just make things run” -- and what steps can be taken toprepare for necessary leadership roles within and beyond engineering.Richard George Weingardt is the founder of Richard Weingardt Consultants, Inc., a Denver, Coloradobasedconsulting engineering firm specializing in structural engineering.
