The mode is used to plot influence lines for multi-span continuous beams of constant section. Only the influence lines of bending moments and shear forces are considered.
The design of a multi-span beam is specified in the Design solution group of the General Properties tab. It is defined by the number of spans, their length and the presence or absence of cantilevers. If you specify stiff clamping (on the right and/or on the left), the respective cantilever can no longer be defined. The Section group is used to select a span and specify the distance from its left edge to a section for which you want to plot the influence lines. The influence lines can be obtained by clicking the Calculate button or opening the Influence Lines tab.
The Influence Lines tab provides the structural scheme of the beam and two influence lines (of bending moments and shear forces). If you place the mouse pointer over any point along the beam, the values of the moment and the shear force in the pointed section will be displayed.
Tables on the left from the influence lines contain information on the areas of the influence lines in segments between zero points. These values can be used to find the moment and/or the shear force under an evenly distributed temporary load.
