Reliability Analysis Of Shallow Foundations Bearing Capacity On Sand, Ali Alhajami
Reliability Analysis Of Shallow Foundations Bearing Capacity On Sand, Ali Alhajami
Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research
Bearing capacity of shallow foundation is one of the most challenging problems for engineers. The difficulty comes from multiple sources of variability and uncertainty. There is an uncertainty in live load. Soil properties including: unit weight, cohesion, and angle of friction represent sources of variability in the determining bearing capacity. The current theories used in practice only estimate bearing capacity and does not give an exact value for it because of these sources of variability. Currently, there are Terzaghi, Meyerhof, Vesic, and Hansen theories for dealing with this problem. Based on previous research Terzaghi theory was found to be the …
Resilience Of Bridges Following Aftershocks, Diego Francisco Espinosa
Resilience Of Bridges Following Aftershocks, Diego Francisco Espinosa
Electronic Theses and Dissertations
The ability to predict the reduction in capacity of a structure after an earthquake is vital in the process of assessing a structure after a main-shock or an after-shock. Main-shocks are normally followed by a few aftershocks in a short period of time. Researchers in the past have focused for the most part on the effects of main-shocks on buildings. Very little research has been performed on the ability to predict the reduction in capacity of bridges in aftershocks. This thesis focuses on providing a way of assessing the reduction in capacity for main-shocks as compared to aftershocks and the …
