Abstract
The joint U.S. State Department-Chilean Fulbright Program sent senior specialists to Chile after the 2010 "Maule" earthquake to perform collaborative studies with faculty from Chile's main universities. The study described here found that concrete-girder bridges built since 1995 without diaphragms and shear keys suffered extensive damage while older bridges designed and built with these features did not suffer as greatly from twisting or rotation about the vertical axis. Because of the steepness of embankment slopes, many bridge abutments exhibited slumping. Concrete retaining walls and mechanically stabilized embankment walls were not damaged. Liquefaction induced pier settlements and lateral spreading impacted bridge performance in coastal regions.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
