CE - 809: Structural Dynamics
Description and Rationale
• As modern structures are becoming slender and light, they are also becoming more susceptible to dynamic loadings.
• Various examples of real-life dynamic problems that frequently confront civil engineers include:
• Aerodynamic stability of long-span bridges
• Earthquake response of multi-story buildings
• Impact of moving vehicles on highway structures, etc.
• The traditional engineering solutions to these problems, based on “static force” and “static response”, are no longer valid in most cases.
• Many of these problems have to be tackled by applying the knowledge of structural dynamics.
Thus, a basic understanding of the dynamic behavior of structures as well as the underlying principles is essential for structural engineers.
With recent advances in computing and modeling tools, and with growing challenges in terms of increase in population, urbanization, complexities in structural forms and innovative systems, the practicing structural engineers and designers nowadays need to equip themselves with various advanced skills. The demand and complexity is rapidly increasing for built environment including accommodation, offices, and commercial areas to accommodate rapidly growing urban population. Resultantly, the cities and infrastructure of future will need to be denser, complex and taller. These challenges require great expertise and computational capabilities in terms of using state-of-the-art analysis procedures, latest computer modeling software and developing insight into the complex dynamic behavior of structures.
Pakistan is located on a highly earthquake-prone and seismically active part of the world. The country lies on a tectonically active Himalayan orogenic belt developed as a result of slow collision (extended over last 30-40 million years) among the Indian, Arabian, and Eurasian tectonic plates. This geological setting has resulted in a number of active seismic sources and faults in the region which are capable of producing moderate- to large-magnitude earthquakes. Besides having a high level of seismic hazard, the country is also confronted over the years with high rate of population increase and rapid growth of urbanization. With all these challenges and high seismic risk, there is an urgent need of equipping the practicing engineers, designers, structural engineering students with state-of-the-art information about the dynamic analysis of structures.
This course aims to develop basic expertise and skill among students about various practical aspects of dynamic analysis of buildings and structures.
