LRFD Design and Construction of Shallow Foundations for Highway Bridge Structures

项目名称：	LRFD Design and Construction of Shallow Foundations for Highway Bridge Structures
摘要：	Shallow foundations are used for a large percentage of bridges, retaining walls, and other transportation structures. Research is needed to develop reliability-based resistance factors and to incorporate those factors into design specifications. Transportation agencies across the nation will be using these specifications. LRFD design specifications for shallow foundations of highway structures should be developed using a reliability-based calibration procedure, consistent with the calibration of load and resistance factors for bridge superstructures. Load and resistance factors should account for uncertainties related to load combinations, site conditions, soil and rock type and properties, and methods of testing and analysis. It is believed that resistance factors for shallow foundations in Section 10 of the current AASHTO LRFD Bridge Design Specifications do not satisfy these requirements. The objective of this project was to develop recommended changes to Section 10 of the AASHTO LRFD Bridge Design Specifications for the strength limit state design of shallow foundations.
