Considerations For The Tornado-Resilient Structural Design Of Low-Rise Buildings, Cody J. Van Der Kooi
Considerations For The Tornado-Resilient Structural Design Of Low-Rise Buildings, Cody J. Van Der Kooi
Electronic Thesis and Dissertation Repository
Building codes and standards have begun to incorporate tornado-specific loads to help protect community infrastructure against these potentially devastating storms, with a specific focus on low-rise buildings. The current tornado design loads are derived from atmospheric boundary layer (ABL) winds, even though it is relatively unclear to what extent tornado and ABL wind loads are equivalent for a given intensity. This research focuses on the tornado-resilient design of the main wind force resisting system (MWFRS) and component and cladding (C&C) elements of a low-rise gable roof building. Tornado loads derived from the results of experiments completed in a vortex simulator …
Uncertainties In Internal Pressure Of Oil Pipelines And Implications For The Reliability Analysis, Yue Liu
Uncertainties In Internal Pressure Of Oil Pipelines And Implications For The Reliability Analysis, Yue Liu
Electronic Thesis and Dissertation Repository
The internal pressure is the most important operational load for oil and gas pipelines. The maximum operating pressure (MOP) is the maximum pressure the pipeline is qualified to be operated according to a given standard. In deterministic fitness-for-service (FFS) assessment of in-service pipelines containing flaws such as corrosion defects and cracks, the remaining pressure containment capacity of the pipeline is evaluated and compared with MOP multiplied by a factor of safety to determine if immediate rehabilitation actions for the pipeline are necessary. However, the actual internal pressure of an in-service pipeline is however uncertain and fluctuates with time. Due to …
