Abstract

Abstract

Λ-shaped folding plate grid structure is a type of folding plate structure， and its component element form is Λ-shaped. First， the classification of this kind of structure and the configuration of the Λ-shaped folding plate elements were introduced. Then， a static analysis of the folding plate grid structure with isosceles triangular Λ-elements was carried out， and formulas for the moment of inertia， the stresses in the upper and lower chords， and deflection were derived. Subsequently， a series of key problems related to the Λ-shaped folding plate grid structure were studied， including the flexural rigidity of the grid structure， the out-of-plane stability of its compression chords， the effects of uneven snow load distribution， and some strengthening measures necessary for cantilevered Λ-shaped folding plate grid structures. Finally， an economic analysis of Λ-shaped folding plate grid structures was conducted. Focusing on the steel consumption of the top and bottom chords， the relationship between steel consumption and the form of the Λ-shape element was established.
