Alashker, Yasser, Auteur ; Honghao Li, Auteur ; Sherif El-Tawil, Auteur |Assumptions must necessarily be made when the collapse response of structures is investigated using simulation models. The type and extent of modeling assumptions depend on the computational resources available, modeling expertise, and results s[...]

Chung-Chan Hung, Auteur ; Sherif El-Tawil, Auteur |One of the weaknesses of the operator splitting method (OSM) is that its corrector step employs the approximation that incremental forces are linearly related to the tested structure's initial stiffness matrix. This paper presents a new predicto[...]

Chung-Chan Hung, Auteur ; Sherif El-Tawil, Auteur |Researchers have long recognized the importance and potential benefits of utilizing the tangent stiffness matrix of a test specimen in hybrid simulations employing implicit and mixed-integration schemes. However, the computation of the tangent s[...]

Alashker, Yasser, Auteur ; Sherif El-Tawil, Auteur ; Sadek, Fahim, Auteur |This paper discusses the progressive collapse resistance of steel-concrete composite floors in which steel beams are attached to columns through shear tabs. This is a common type of system used for the gravity bay portions of steel buildings. Th[...]

Chung-Chan Hung, Auteur ; Sherif El-Tawil, Auteur |High-performance fiber-reinforced concrete (HPFRC) materials have a unique strain-hardening behavior in tension that translates into enhanced structural response, especially under reversed cyclic loading. Recent experimental research has shown t[...]

Sherif El-Tawil, Auteur ; Harries, Kent A., Auteur ; Patrick J. Fortney, Auteur |Hybrid coupled walls (HCWs) are comprised of two or more reinforced concrete wall piers connected with steel coupling beams distributed over the height of the structure. Extensive research over the past several decades suggests that such systems[...]
