The current project is designed to assess the level of damage that a realistic irregular bridge will undergo after the occurrence of an earthquake. This study encourages an improved understanding of post-seismic return to service and repair of an irregular bridge. A more sophisticated approach will be used to analyze the complex vibrations of the bridge in response to a seismic excitation and to simulate the progressive collapse of the bridge during an earthquake.
Surface waters, such as lakes and rivers, often have high amounts of natural organic matter formed from decaying plants and animals. Drinking water treatment plants that use these water sources often face with high levels of carcinogenic chlorine disinfection by-products (DBPs) which are result of reaction between natural organic matters and chlorine that is added to water for disinfection. Canadian water quality guidelines set maximum acceptable levels for these harmful DBPs and hence water treatment plants are obliged to come up with appropriate solutions to meet the guidelines.
