Summary: | This paper reviews available experimental and finite element test data pertaining to the negative moment-plastic rotation behavior of continuous-span steel I-girders with compact or ultra-compact flanges. Current American specification formulas for the pier-section strength of these types of members and a moment-plastic rotation model recently developed by the authors are examined against the experimental and finite element test results. Several weaknesses in current specification provisions are observed. The new

model avoids these weaknesses and provides a lower-bound approximation of the complete moment-plastic rotation response at the pier section. |
