Calculation features of compressed-bent build-up timber columns with nonlinear-deformable shear bracings

Abstract Object of research is build-up compressed–bent and eccentrically compressed columns on yielding nonlinear – deformable shear bracings. Purpose the development a numerical method for calculation columns, allowing to take in account influence deflection elastic axis bar increment bending moment from action longitudinal compressive force dependence between forces deformations Problem-solving consists dividing column into separate sections, system equations compiled condition equality concentrated shears. The loading process divided set number stages, at each bracings, stresses branches, buckling function element are determined. obtained values bracings used specify stiffness component arising due eccentric application when deflecting. To obtain resulting values, forces, deflections branches stage summed up.
