JTRP Technical Reports
Debris accumulation at bridge piers has been a significant problem at a number of bridge sites in Indiana, increasing risks of upstream flooding, scour, and stream instability. The current study aimed at identifying factors contributing to debris accumulation in order to formulate guidelines for the design of new bridges that would minimize their occurrence or impact. Three related approaches were taken: i) a systematic study of the available underwater bridge inspections reports, ii) a program of periodic visits and visual examination of bridge sites that were thought to be prone to debris accumulation, and iii) continued video monitoring of three …

JTRP Technical Reports
The literature review of prior heat straightening research indicated that significant research has been conducted on the development of: (i) heat straightening repair techniques and their field implementation, (ii) guidelines and recommendations for heat straightening repair, (iii) empirical procedures for estimating plastic rotations achieved during heat straightening, (iv) empirical procedures for predicting residual stresses caused by heat straightening, and (v) the effects of heat straightening on the structural properties of repaired bridges. Currently, there is a need for additional research on: (a) the fatigue performance of heat straightened beams, (ii) the effects of single and multiple heat straightening on the …
