A model to simulate special concentrically braced frames nonlinear modeling of concentrically braced frames

May 11, 2012 · A fracture modeling approach simulated the nonlinear, cyclic response of SCBFs by correlating onset of fracture to the maximum strain range in the brace. The model accounts for important brace design parameters including slenderness, compactness, and yield strength.A simplified model for seismic response prediction of nonlinear modeling of concentrically braced framesmodified shear-building models more accurately estimate the nonlinear dynamic response of the corresponding concentrically braced frames compare to the conventional shear-building models. 2- Modeling and assumptions In the present study, three steel concentric braced frames with 5, 10 and 15 stories have been selected (Fig. 1).
