<p>This paper investigates experimentally the effectiveness of a new seismic design philosophy, in which soil failure is &ldquo;utilized&rdquo; to protect the superstructure. A physical model of a simple bridge pier is used as an example. Two alternatives ...

<p>Soil-structure interaction may play a major role in the seismic response of a bridge structure. Specifically, soil layers of low stiffness and strength may result in permanent displacement of the abutments and foundations, thus imposing important kinematic ...

<p>This Reference Manual is intended principally to serve as a supplement to the Participant&rsquo;s Workbook for the FHWA&rsquo;s National Highway Institute Course on Load and Resistance Factor Design for Highway Bridge Substructures. The Reference Manual ...

This report explores current practices pertaining to each step of the design process, along with the limitations identifies emerging and promising technologies examines the principal challenges in advancing the state of the practice and investigates future ...

<p>This research project was funded to investigate the possibility that, by measuring and modeling the dynamic response characteristics of a bridge substructure, it might be possible to determine the condition and safety of the substructure and identify its ...

This report contains the findings of a study to develop resistance factors for driven pile and drilled shaft foundations. These factors are recommended for inclusion in Section 10 of the AASHTO LRFD Bridge Design Specifications to reflect current best practice ...

<p>Presented here is an analysis of the effects of soil-foundation-structure interaction (SFSI) on seismic response of highway bridges. Of particular importance is the issue of input motions, their scaling and application to the SFS models. The analysis presented ...

<p>Load factor design (LFD) codes have been used in the US since the 1970&rsquo;s, and in the highway industry since 1977, but their application was limited to the design of superstructure components. Introduction of the AASHTO LRFD Bridge Design Specifications ...
