Biography
Roberto Leon is a Professor in the School of Civil and Environmental Engineering at the Georgia Institute of Technology.
His research interests center on dynamic behavior and design of structures with partially-restrained composite connections, composite floors and floor systems, bond of reinforcement under cyclic loads, testing of full-scale and model structures in the laboratory, and field instrumentation of structures.
Roberto’s research includes extensive experience with seismic performance of steel systems, with emphasis on bolted connections and flexible framing systems, and original research on performance of composite joist floor systems and trussed girder systems.
Roberto is a member of the AISC Specification Committee, the AISC Seismic Design Committee, the AISC Load, Analysis and Systems Committee, and the BSSC Provisions Update Committee. He is a registered professional engineer in Minnesota, the co-author of a book on composite construction, a non-technical book on bridges and tunnels, and is the author and co-author of over 80 articles in refereed journals.
Abstract
In order to be included in the 2009/2010 cycle of the International Building Code, the American Institute of Steel Construction has recently completed news version of its specifications for steel and composite structures under normal and seismic loads. The provisions for buildings contain significant expansion of the scope for composite columns and stability provisions. For composite columns, in particular, new rules for concrete-filled columns with slender steel sections and for load transfer between steel and concrete have been included. The accompanying seismic design provisions have been completely rewritten to match the format of the standard for non-seismic loads, and contain extensive new provisions for composite systems. This paper presents some highlights of these changes, with emphasis on composite members and systems.
