PCI eLearning Course T520: Girder Stability-Introductory Material and Hanging Girders-Mast 1989, Lateral Stability Part 2

Mast 1989, Lateral Stability Part 2

Pdf Summary

This special report discusses the lateral stability of long prestressed concrete beams and presents a theory for evaluating their stability. The theory is verified through testing and the results align with predictions. The report emphasizes the importance of understanding beam behavior on elastic supports. The effective stiffness of cracked prestressed concrete beams is explored and a simplified relationship is proposed. The report also discusses factors of safety, measurements of roll stiffness, and the use of elastomeric bearing pads.
