Proposed Guidelines for Performance-Based Seismic Bridge Design

项目名称：	Proposed Guidelines for Performance-Based Seismic Bridge Design
摘要：	The current AASHTO Guide Specifications for LRFD Seismic Bridge Design �guide specifications� do not address performance-based seismic bridge design or provide design criteria for bridges that are critical or essential. Furthermore, the guide specifications do not provide direction to assist owners and designers who wish to consider seismic risk mitigation beyond the life safety objective. A bridge may have different operational requirements depending on the post-earthquake functions (for example, serving the community by providing emergency vehicle access), which would suggest a higher performance objective than the basic levels included in the design codes. Research is needed to provide guidance to help bridge owners and designers define enhanced seismic performance objectives and design bridges to meet those objectives. The objectives of this research were to develop: (1) proposed AASHTO guidelines for performance-based seismic bridge design and (2) proposed revisions to the AASHTO Guide Specifications for LRFD Seismic Bridge Design to link with the proposed AASHTO guidelines for performance-based seismic bridge design.
