Speed School of Engineering University of LouisvilleDr. McGinley is a structural engineer and building scientist with an excess of 25 years of research and forensic engineering practice in building systems. Prior to joining U of L, he served 20 years at North Carolina A & T State University in the Civil, Architectural, Agricultural and Environmental Engineering Department. He is an expert in masonry building systems, in particular, masonry building envelopes. Dr. McGinley's research has included research on the structural performance of masonry walls, water penetration experiments on envelopes and the building envelope performance of brick veneer and steel stud wall systems. He has also been involved in, multidiscipline efforts on the evaluation of the energy systems of existing buildings and demonstration projects evaluating condensing heat exchangers and thermal mass effects of night time ventilation. He has been a primary author of all seven editions of the Masonry Designers Guide.Dr. McGinley has been actively involved in the Masonry Society as the Chair of the Design Practices committee (1992-1998) and member of the research committee, member of the Board of Directors and the code and standards committee. He is also involved with ASTM on committees C-12 and C15 and currently chairs the Subcommittee on Lab accreditation and the Task groups on the Bond Wrench testing Apparatus and Field evaluation of mortars. He received the ASTM Gilbert C. Robinson Memorial Award in 2001 and the ASTM Award of Merit and title of Fellow in 2008 for his efforts at ASTM. In September 2012, he received the TMS - J.B. Scalzi Research Award for his masonry related research contributions. He is also a member of the Masonry Joint Standards Committee, served as Chairman of the Reinforcing and Connectors Subcommittee and now chairs the Flexural Axial Load and Shear Subcommittee.

Brick veneer wall systems have been damaged under severe out-of-plane seismic and wind loads. Consequently, the out-of-plane behavior of these wall systems has been investigated under both static and dynamic loading, but with a focus on low-rise buildings. This paper investigates the out-of-plane seismic performance of these wall systems in medium-rise buildings. Current prescriptive code requirements for these systems are evaluated in typical medium-rise steel and concrete building frames. Analytical models of the building frames and the veneer wall systems are developed. These combined frame and wall system models are subjected to the design based and maximum considered earthquake levels of selected ground motions. A parametric study was conducted over the range of stiffness and strength of these systems encountered in common US construction practice. An incremental dynamic analysis was performed until the models became unstable. Using this approach, it was possible to identify the component of the system that would potentially lead to its “Failure” or “Collapse”. As a result of this analysis, it was concluded that the current prescriptive code requirements for masonry veneer wall systems are adequate for seismic loading in the critical out-of-plane direction. The analysis also found that the code provisions are quite conservative for flexible frames. As the frame flexibility decreased, the conservatism of the provisions also decreased, and were found to be much less conservative for the stiffest frame system investigated.
