Example | C2. 1 Introduction in this chapter, we describe methods for determining the equation of the deflection curve of beams and finding deflection and slope at specific points along the axis of the beam 9. In this case, the application of a ten-sile stress produces elongation in the x-direction and contraction in the y-direction, and the dis-torted element remains rectangular. The effective flange width is automatically calculated for the specified Code based on the distance to edge or adjacent beam specified in the Beam - Composite command. Contextual translation of "composite beam" into Dutch.
