Abstract

To improve the assessment of steel braced frame structures under earthquake and other severe loading conditions, a new class of physical theory model is implemented using the Open Sees computational framework. The model can simulate flexural and axial behavior, including global lateral buckling and low-cycle-fatigue initiated fracture. Full-scale experiments of individual braces are used to validate and calibrate the model. Using calibrated models, a three-story, code compliant, chevron braced steel frame is analyzed considering a wide variety of seismic excitations. These analyses are used to assess the ability of the structure to retain specific levels of post-earthquake lateral load capacity. Results indicate that representative short-period braced frames are likely to loose a significant portion of their initial lateral load resisting capacity as a result of rare and unusually severe earthquake motions.
