Noise & Vibration
This case study describes a design problem faced by the Indian Institute of Technology-Madras (IIT-Madras), a preeminent engineering institution in India, and Larsen & Toubro (L&T), one of Indiaâ€™s largest construction firms. Due to the rapidly increasing student population, IIT-Madras needs to construct more on-campus residences (hostels). However, because it is situated on the beautiful Guidny National Park, the university is restricted to 24% land use.
L&T recently completed a new group of high-rise hostels for IIT-Madras, but the older, sprawling-style hostels remain a popular choice among students. The two designs vary greatly in the areas of thermal comfort and social function. This case study explores how to design thermally comfortable and socially functional spaces while minimizing university land use.
The project head for the construction of an IT park (about four million square feet) in Chennai, India has to finalize the glazing system for his project. This glazing system must comply with the energy code requirements that are outlined in his contract. He turns to the projectâ€™s architect, along with Mr. Nandakumar, the FaÃ§ade Engineer from the Center for Excellence and Futuristic Development (CEFD) at the Chennai branch of Larsen and Toubro, to arrive at a solution.
The field of Nondestructive Testing (NDT) is a very broad, interdisciplinary field that plays a critical role in assuring that structural components and systems perform their function in a reliable and cost effective fashion. NDT technicians and engineers define and implement tests that locate and characterize material conditions and flaws that might otherwise cause planes to crash, reactors to fail, trains to derail, pipelines to burst, and a variety of less visible, but equally troubling events. These tests are performed in a manner that does not affect the future usefulness of the object or material. In other words, NDT allows parts and material to be inspected and measured without damaging them. Because it allows inspection without interfering with a product’s final use, NDT provides an excellent balance between quality control and cost-effectiveness.
This multimedia courseware focuses on an acoustical design of the polyvalent hall at the Swami Vivekananda International Convention Center on the island of Mauritius. The multi-use hall was praised as a “fabulous building and quite and achievement” after successfully hosting a United Nations conference without any acoustical problems. Later, as a band rehearsed for the building’s first rock concert, the sound quality fell severely short of expectations. A problem arose with the loud music, requiring a reconsideration of the hall’s design before it could provide satisfactory acoustics for any similar events.
The materials provided here will introduce students to the following concepts:
- Solving a design problem using global engineering standards
- Applying the mechanics of acoustical design and acoustics engineering
- Evaluating multiple alternative solutions to a design problem using a Decision Support System
