Design Load Combinations of the 2012 IBC
The design load combinations in Section 1605 of the IBC and the load combinations with overstrength factor in ASCE 7-10 Section 12.4 are known to cause a lot of confusion among code users. This web seminar is aimed at removing that confusion by explaining the strength design, the basic allowable stress design (ASD), and the alternative basic ASD load combinations in Section 1605 of the 2012 IBC. The equivalency or lack thereof among the three sets of load combinations is discussed as well as advantages of using one method over another. It is pointed out that 2012 IBC Section 1605 requires the use of the load combinations with overstrength factor in Section 12.4 in certain situations. These situations and the load combinations with overstrength factor themselves are explained. Numerical examples are given of combining load effects using the load combinations in IBC Section 1605 and ASCE 7-10 Section 12.4.

Dr. S. K. Ghosh is known internationally for his work in earthquake engineering. He has influenced seismic design provisions in the United States for many years by serving on or chairing numerous committees and advisory panels. He specializes in the analysis and design, including wind and earthquake resistant design, of reinforced and prestressed concrete structures. Dr. Ghosh is active on many national technical committees and is a fellow of ASCE, SEI, ACI, and PCI. He is a member of ACI Committee 318, Standard Building Code, and the ASCE 7 Standard Committee (Minimum Design Loads for Buildings and Other Structures). He is a former member of the Boards of Direction of the Building Seismic Safety Council (BSSC), the American Concrete Institute (ACI), and the Earthquake Engineering Research Institute (EERI). In addition to authoring many publications in the area of structural design, he has investigated and reported on structural performance in recent earthquakes.
Dr. Hajihashemi joined S. K. Ghosh Associates Inc. in June 2013 after obtaining his Ph.D. from the University of Memphis. During his Ph.D. program, he conducted a research project, funded by Tennessee DOT, on the evaluation of displacement-based seismic design methods in current highway bridge codes and specifications. He pursued his interests in seismic and structural code-related activities by joining SKGA and is currently engaged in producing code support publications, his first being the Application Guide for the 2012 IBC Concrete Provisions.
