Key Aspects For Lrfd Implementation For Driven Pile Capacity By Dynamic Methods, Natalie R. Ehrlich
Key Aspects For Lrfd Implementation For Driven Pile Capacity By Dynamic Methods, Natalie R. Ehrlich
Civil and Environmental Engineering Master's Project Reports
Inputs and interpretation procedures for pile wave equation analysis, which correlates measured field dynamic driving response to axial pile static capacity, are highly dependent on site-specific soil conditions and field practices. The 6th Edition of the AASHTO LRFD Bridge Design Specifications provide generalized guidelines for pile design, but do not account for variability in region-specific soils and field practices. A comprehensive literature review of region-specific resistance factor recalibration efforts across the U.S. has given insight into the range of implementation issues encountered, especially the key decisions around choosing a restrike (BOR), along with measures of efficiency and treatment of …
Parametric Study Of Rocking Shallow Foundations Under Seismic Excitation, Benjamin I. Herdrich
Parametric Study Of Rocking Shallow Foundations Under Seismic Excitation, Benjamin I. Herdrich
Civil and Environmental Engineering Master's Project Reports
Conventional design of structures relies on incorporating a certain level of inelastic deformation into select components to provide seismic energy dissipation, while ensuring the foundation remains relatively stationary. However, this inelasticity comes at the cost of severe damage to the structure, which often is no longer suitable to occupancy after a seismic event. In contrast with conventional structures, structures with rocking foundations shift the ductility demands away from the structure itself, and onto the underlying soil, which may result in less damage and greater stability. The purpose of this study is to explore the behavior and performance of a simple …
