Changes between ASCE 7-05 and ASCE 7-10
This seminar presents a detailed and comprehensive overview of the substantive changes from ASCE 7-05 to ASCE 7-10. Major revisions have taken place in both the wind design and the seismic design provisions. Wind design has changed more substantially than any time since the publication of ASCE 7-95. The reorganization of the wind provisions are addressed and the changes to the wind maps and the corresponding changes to the load factors are explained. In addition, the new simplified version of the general analytical procedure under Method 2, which is applicable to buildings of all heights, is addressed.
Explanation of the new seismic maps is presented as well as how they affect seismic design results. There are many other significant changes to the ASCE 7 seismic provisions (Chapters 11, 12, 21 and 22), such as changes to Table 12.2-1 (the R-values table) and new provisions for wall anchorage, that are included.
In addition to covering changes to the wind and seismic provisions, the seminar also presents an overview of the substantive changes to the other provisions found in ASCE 7. These include the introduction of performance-based design procedures, enhancement of the general structural integrity requirements, revisions to load combinations, new live loads, and changes to snow load provisions.
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.
