Quantification of intermediate diaphragm effects on load distributions of prestressed concrete girder bridges

摘要

While there has been much research on the effects of intermediate diaphragms on load distributions in the past few decades, no significant work was conducted to develop convenient formulas to quantify these effects. Through this study, expressions were developed to account for the influence of intermediate diaphragms on load distributions for prestressed concrete bridges. Values obtained from these expressions were found to be accurate when they were compared with those from a 3-D finite-element analysis for different bridge configurations.
