Seminar Description
Have you ever wondered if your building has an undetected irregularity and if there are code provisions that were not applied but should have been? This web seminar will put those fears to rest because the seminar thoroughly covers each type of horizontal and vertical irregularity defined in ASCE 7-16. The definitions are explained in detail with illustrations. The many code provisions that are triggered when a particular type of horizontal or vertical irregularity exists are next discussed in detail. The provisions range from 1) requiring that dynamic, rather than equivalent static, analysis be used as the basis of design to 2) requiring that structures with certain structural irregularities not be built beyond a certain height or not be built at all, if they are assigned to high seismic design categories to 3) setting redundancy factor equal to 1.3 because of an extreme torsional irregularity. The background to these requirements is provided, whenever practicable and reasons why buildings need to be penalized for structural irregularities are explained. Frequently asked questions and answers on the identification of structural irregularities and how they affect the design of the structure are also presented. Any changes in structural irregularity provisions to be made in ASCE 7-22, which will be adopted by the 2024 IBC, are noted. The web seminar includes three question-and-answer periods.The views and opinions expressed in this seminar are those of the speaker(s) and do not necessarily reflect those held by S. K. Ghosh Associates LLC.
Speaker Bio
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.
