Lecture on "Fundamentals of Seismic Design of High-Rise Buildings" was held on October 27, 2021, at 16:00 via Zoom.
The lecturer was full professor Dr Ratko Salatić, M.Sc. Civil Engineering, from the Faculty of Civil Engineering, University of Belgrade.
Below are the abstract of the lecture, the lecturer’s biography, and the video recording of the lecture.
Abstract
In seismically active areas, seismic loads represent the most intense loads acting on a structure, thus requiring special attention in the design process. The fundamental characteristics of seismic design are its complexity and demanding nature. Moreover, the probability of seismic load occurrence is significantly lower than that of other types of loads. Seismic design is mandatory for all structures built on highly seismic soil. This creates a serious engineering challenge to balance the complexity of the problem with clear and efficient design methods. The biggest challenge in such analyses is the nonlinear response of the structure under the strongest expected earthquakes.
The lecture focuses on the fundamentals of seismic design for high-rise buildings, with a critical review of well-known seismic design methods. To find the balance between complexity and efficiency in design, assumptions, as well as advantages and disadvantages of each seismic design method, will be considered. Since the application of Eurocode 8 provisions is significantly more complex than the previous, now obsolete regulations, a thorough understanding of current design methods is essential for practical use. Besides reviewing all seismic analysis methods, the lecture will cover current design methods: spectral analysis, direct dynamic integration, equivalent static load method, multimodal analysis, simplified modal analysis, ductility factor method, and pushover analysis. Modeling of the structure, assumptions, and steps in each method will be discussed. The lecture is limited to high-rise buildings, which represent the largest group of structures requiring seismic design.
Speaker biography
Dr Ratko Salatić, M.Sc. Civil Engineering, is a professor at the Faculty of Civil Engineering, University of Belgrade, employed there since 1988. After graduating, he worked at “Energoprojekt Hidroinženjering” in the Special Purposes Bureau. He earned his master’s and doctoral degrees at the Faculty of Civil Engineering in Belgrade, specializing in seismic analysis. At the faculty, he teaches undergraduate, master’s, and doctoral courses including Structural Dynamics and Earthquake Engineering, Structural Stability, Theory of Structures 2, Special Chapters of Earthquake Engineering, Seismic Analysis of Structures, Advanced Structural Dynamics, and Advanced Structural Stability. Within the broad field of structural theory, Dr Salatić focuses on the dynamics and stability of structures, with most of his research addressing these areas. His work investigates modern problems related to the stability of line and surface supports within their post-elastic behavior. He also researches and analyzes the nonlinear behavior of both reinforced concrete and steel structures under seismic loads, which were the topics of his master’s thesis and doctoral dissertation. Additionally, under the mentorship of Prof. Dr. Miodrag Sekulović, Dr Salatić was among the first at the faculty to actively study structural behavior control. He served as the president of the Continuing Education Commission of the Serbian Chamber of Engineers from 2005 to 2017. He is a member of the Expert Operational Team of the Republic Emergency Headquarters. In 2017, he was one of the nine founders of the Serbian Association for Earthquake Engineering.
