Abstract: This paper reviews eight previous studies on the variable-amplitude (VA) fatigue strength of structural steel details: (1) four studies in the

Abstract: Composite steel-concrete bridges constitute a major portion of the national bridge inventory. Many of these structures are approaching or have passed their service lives and are in need of repair and rehabilitation. External ...

Abstract: The paper introduces a design space for the design of prestressing tendons concentric with members for strengthening steel truss bridges. The design space contains all feasible solutions for the cross-sectional area of the ...

Abstract: The writers summarize all fatigue test data for cover plates on steel beams that were reported since 1969. The earlier studies established the fatigue strength of thin cover plates of Category E fatigue strength as well ...

Abstract: This paper presents the fatigue behavior of 39 welded and 12 cover-plated beams fabricated from A588 weathering steel. One set of beams was boldly exposed to the environment; the other was exposed under a metal deck that ...

Abstract: A practical design optimization of fiber-reinforced polymer (FRP) patches for repairing fatigue cracks in metallic structures is presented. The design procedure combines finite-element (FE), genetic programming (GP), and ...

Abstract: The finite element method was used to develop accurate stress intensity factor (SIF) solutions for two-tip web cracks and symmetric three-tip cracks in I-beams under tension or bending. Governing parameters for cracked ...

Abstract: This paper addresses the debonding strength of partial-length, adhesively bonded carbon fiber-reinforced polymer (CFRP) plates that are used to strengthen steel beams. Bonded CFRP plates tend to debond under static and ...
