Passive Force On Skewed Abutments With Mechanically Stabilized Earth (Mse) Wingwalls Based On Large-Scale Tests, Bryan William Franke
Passive Force On Skewed Abutments With Mechanically Stabilized Earth (Mse) Wingwalls Based On Large-Scale Tests, Bryan William Franke
Theses and Dissertations
Passive force-deflection behavior for densely compacted backfills must be considered in bridge design to ensure adequate resistance to both seismic and thermally induced forces. Current codes and practices do not distinguish between skewed and non-skewed bridge abutment geometries; however, in recent years, numerical models and small-scale, plane-strain laboratory tests have suggested a significant reduction in passive force for skewed bridge abutments. Also, various case studies have suggested higher soil stresses might be experienced on the acute side of the skew angle. For these reasons, three large-scale tests were performed with abutment skew angles of 0, 15 and 30 degrees using …
Lateral Resistance Of Piles Near Vertical Mse Abutment Walls At Provo Center Street, Kent R. Nelson
Lateral Resistance Of Piles Near Vertical Mse Abutment Walls At Provo Center Street, Kent R. Nelson
Theses and Dissertations
Full scale lateral load tests were performed on four piles located at various distances behind MSE walls. Three of the four test piles were production piles used to support bridges, and the other pile a production pile used as part of the bridge abutment. The objective of the testing was to determine the effect of spacing from the wall on the lateral resistance of the piles and on the force resisted by the MSE reinforcement. Lateral load-displacement curves were developed for pile at various spacing and with various reinforcement ratio (reinforcement length, L divided by wall height, H). The force …
