This seminar addresses the following hot topics which have generated many questions and quite a bit of discussion among structural engineers. #1: New Simplified Wind Design Provisions for the 2009 IBC - A simplified wind design procedure, with broader applicability than that of Method 1 - Simplified Procedure of ASCE 7-05/2006 IBC, has been approved for inclusion in the 2009 IBC. The procedure is an alternative to Method 2 - Analytical Procedure of ASCE 7-05/2006 IBC and is in some ways similar to the wind design procedure that was in the 1997 UBC. The procedure is discussed in detail. #2: Load Combinations - The three sets of load combination equations of ASCE 7-05 and the 2006 IBC are discussed and their differences, such as in the dead load factor, are addressed. The advantages and disadvantages of using one set versus another are explained. The special seismic load combinations or load combinations with overstrength are also discussed. #3: Redundancy - The redundancy factor of ASCE 7-05 and the 2006 IBC, which is required to be determined in the design of structures assigned to Seismic Design Categories (SDC) D through F, is explained and frequently asked questions are answered. #4: Diaphragm: Rigid or Flexible? - A flow chart is presented and explained so that, given any diaphragm situation, its flexible, semi-rigid, or rigid classification according to the provisions of ASCE 7-05 can be determined conclusively and quickly. #5: Significant 2009 IBC Concrete Chapter (ACI 318-08) Changes - A large number of very substantive changes have been made from the 2005 to the 2008 edition of ACI 318. Selected changes of major importance are presented and briefly discussed in this session. ACI 318-08 is referenced by the 2009 IBC. Thus, the changes discussed are also the changes in concrete design provisions from the 2006 to the 2009 edition of the IBC. #6: Nonstructural Components and Nonbuilding Structures: What does the 2006 IBC require? - The seismic design requirements for nonstructural components and nonbuilding structures are explained. Requirements and exceptions are outlined including a discussion of the seismic force demand equations for nonstructural components, nonbuilding structures similar to buildings and nonbuilding structures not similar to buildings. Guidance on how to determine whether or not an item is a nonstructural component or a nonbuilding structure is provided. Total Duration: 6 hrs 22 mins PDH Earned: 6

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.

Ms. Susan Dowty received her Bachelor of Science degree in Civil Engineering from Cal Poly, San Luis Obispo in 1984 and her Master of Science degree from California State University, Long Beach in 1990. She is a registered civil and structural engineer in the State of California and has over twenty years experience in the administration and development of the Uniform Building Code provisions. She has played an active role in the development of structural provisions for the International Building Code, serving as the Structural Committee Secretariat. She has also been instrumental in the development of a number of structural engineering related publications produced by ICC and SKGA. She served as the consultant for the reformat of the ASCE 7-05 seismic provisions and served a four-year term on the California Building Standards Commission.
