| 摘要： | TRB's National Highway Cooperative Research Program (NCHRP) Web-Only Document 245: Bridge Superstructure Tolerance to Total and Differential Foundation Movements develops an understanding of the levels of support movements that bridges may tolerate before exceeding strength or service limit states. This research explores analytical procedures to objectively determine the acceptable levels of bridge foundation movements based upon superstructure tolerance considering American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD) strength and service limit states (Phase II). The report also proposes revisions to the AASHTO LRFD Bridge Design Specifications that provide rational guidance for foundation movement limits that shall include vertical and rotational movements (Phase III and IV). |
