Stability of Building Structural Engineering Based on Fractional Differential Equations

Abstract The compression rod is an important stress member of house building and bridge structure. When the load on reaches critical load, entire structure will lose its stability. We use fractional-order differential equation curvature to bend apply fourth-order equation's general solution establish rod's stability model in construction engineering. In this paper, discrete boundary conditions are applied algebraic system by substitution method obtain characteristic about buckling rod. research found that proposed paper simple. relation deduced reasonable efficient.
