THE APPROXIMATION OF THE EQUATION FOR BENDING STIFFNESS OF TRUSS CONSTRUCTION

Abstract

The bending stiffness of the construction is one of the key factors for stress condition analysis, stability and dynamic behavior. The parameter that directly influences the stiffness of the construction is the cross-section moment of inertia, so its defining is necessary. The way of forming the truss filler is also a parameter that significantly influences the bending stiffness, so the research of its influence is also needed. This paper shows the simplified model which approximately defines the moment of inertia of truss construction. The most usual ways of truss construction filler forming for different spans are analyzed. The truss construction deflection dependence on the way of filling and span of construction is defined.
