Several solid element based brace models were built in ABAQUS software and a quasi-static cyclic axial loading was applied to determine their hysteretic response.
Recommendations are made on how to alter the performance outcome such as using alternative ground motion selection approaches (e.g., conditional mean spectrum), using higher fidelity brace models, and having acceptance criteria based on cumulative ductility demand or energy dissipation.
Other scoliosis brace models include the Providence, the Boston and the Milwaukee.
The Charleston's exaggerated shape, different than the corset-like straightness of other brace models, worked to bend my spine in the opposite direction of the curve.
For the first time, this paper provides a comprehensive bracing model for sheathing-braced stud walls that integrates the two forms of lateral resistance: local and diaphragm.
The intense velocity of x-brace model proportional to ODBS is generated imposing loads by impulsive tendency within the time domain of acceleration.
Elements and parameters of the model were described, comparisons between the model and pinned equivalent bracing model were performed.
The later experimental work on directly knee braced model frames by Zahrai and Jalali (2014) and Sutat et al. (2011) also showed the applicability of this method.
An improved equivalent bracing model of cold-formed steel shear wall with concrete-filled rectangular steel tube column as reinforced end studs was proposed, for seismic analysis of mid-rise cold-formed steel structures.
