Stability of Horizontally Curved I-Girder Bridges During Early-Stage Construction

This proposed project investigates the stability performance of horizontally curved I-girders during construction. Emphasis will be given to early stages of construction when little or no lateral support is provided. Specifically, all phases of construction including girder lifting, placement, transport, erection, as well as concrete deck placement will be studied. Five research tasks will be carried out, which include: (1) survey of bridge erectors, designers, and inspectors; (2) preliminary finite element analysis of the SR-203 bridge under construction; (3) field testing on the SR-203 bridge over Pea River; (4) finite element parametric study, and (5) development of construction guidelines. Upon completion, the project will establish a set of guidelines that provide safe and economical erection practices for curved steel plate girder bridge erections. The results will also provide valuable insights into the safety of current practices and provide guidance to formulate safe construction procedures during curved girder erection and construction. Computer tools, in the format of software program or Excel spread sheet, will be developed to help bridge owners to review and examine the erection plans submitted by contractors.
