Performance Evaluation of Integral Abutment Bridges
To establish a maximum safe length and design details for zero skew steel and concrete bridges with integral abutments, a survey of the highway departments of all 50 states was conducted. The findings of the survey include maximum lengths of integral abutment bridges being constructed, advantages and disadvantages of these bridges as perceived by the various states, and the extent of field obse...
متن کاملpatterns and variations in native and non-native interlanguage pragmatic rating: effects of rater training, intercultural proficiency, and self-assessment
although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...
15 صفحه اولMonitoring of a Swedish Integral Abutment Bridge
One of the most commonly discussed problems regarding bridges with integral abutments is the influence of longitudinal elongation of the superstructure as a result of seasonal temperature variations. A bridge built with integral abutments is often supported by a row of piles made of steel or concrete. The longitudinal elongation of the superstructure induces a displacement and a rotation at the...
متن کاملEarth Pressure behind an Integral Bridge Abutment and Comparison with that behind a Conventional Bridge Abutment under Traffic Loads
Integral bridges are gaining increased popularity because of both economic and fast construction associated with the omission of bearing supports and expansion joints. In the present study the cyclic earth pressure behind integral bridge abutments under traffic surcharges are investigated and compared with that induced behind the abutment of conventional bridges (with isolated deck and abutme...
متن کاملDesign Considerations for Integral Abutment/ Jointless Bridges in the USA
This paper summarizes results of a major study on jointless bridges sponsored by the U.S. Federal Highway Administration. This study included extensive laboratory and field experiments as well as detailed analytical studies. A set of design recommendations were provided. Jointless bridges have reduced maintenance, improved riding quality, lower impact loads, reduced snowplow damage, and structu...
