Research on nonlinear, postbuckling and elasto-plastic analyses of framed structures and curved beams

Nonlinear Analysis of Steel Structure Bent Frame Column Bearing Transverse Concentrated Force at the Top in Factory Buildings

“…The above expression is composed of two parts, namely a sine curve A sin(kx − ϕ) and a sloping straight line A 3 x + A 4 . Since the bending of the compression rod is a nonlinear problem, and the simple superposition method cannot be applied to the nonlinear problem [11,12], the necessary and sufficient condition on which the above two deflection expressions can be superposed is that they are all under the working condition subjected to the vertical load P [13], as shown in Figure 3. Figure 3b-d suggests that the deflection curve in Figure 3b of the compression rod can be decomposed into two parts, that is the sine curve shown in Figure 3c-the deformation deflection curve of the rod under vertical load P and bending moment M at the rod end [14], and the sloping straight line in Figure 3d-the deflection expression of the deflection rod in the linear equilibrium state under vertical load P and horizontal shear force Q 0 and Q L at the end of the rod.…”
