By using a fixed point theorem of mixed monotone operators in cone, this paper studied a fourth-order nonlinear singular boundary value problem, namely a class of elastic beam equation.
In this paper, simply supported reinforced concrete slabs under monotone Sransverse loads are analysed by the nonlinear finite strip method in which low order strips with two joint lines are adopted.
