Abstract: Steel-concrete composite columns are strong and efficient structural members. However, their strength is not consistently recognized within design standards. In particular, current provisions regarding the strength of ...

Abstract: Roof collapses due to ponding instability are among the most frequent structural failures. Although methods of design for other types of instability have evolved and improved with computational advances, the most commonly ...

Abstract: The calculation of flexural buckling loads for structural members remains a relevant topic of practical and theoretical interest. In addition to well-known solutions for prismatic members, solutions are available for the ...

Abstract: Strongback braced frames (SBFs) are a relatively new structural system intended to reduce structural damage during seismic events and improve resilience. SBFs combine buckling-restrained braces, which provide the primary ...

Abstract: Design for stability requires quantifying the effective length of columns. While guidance adopted from building design is sufficient for many cases in bridge design, conservative assumptions are often made when assessing ...

Abstract: This paper presents selected results from an experimental and computational evaluation on the behavior of slender concrete-filled steel tubes (CFTs) under combined axial compression and biaxial flexure. A complex loading ...

Abstract: The direct analysis method is the primary means of assessing system stability within a standard specification. This method, and in particular its use of reduced stiffness, has been thoroughly validated for use in frames ...

Abstract: Design codes for steel structures continue to provide additional opportunities for the use of more advanced methods of nonlinear analysis. As the complexity of the analysis increases, it becomes more important for the ...

Abstract: Resistance factors (ϕ-factors) are reliability-based factors of safety used in load and resistance factor design (LRFD) of structural systems. The ϕ-factors specified in the consensus standard for the structural design of ...
