About skyline plots

When you select the "With Span Detailing" or "User Provided Reinf" contexts, RAM Concept plots the reinforcement with a "skyline" plot.

In a skyline plot, each calculated value is valid for a portion of the span (as shown by a horizontal line) instead of the values being interpolated between cross sections. While this is primarily just a graphical difference, the actual detailing of the reinforcement into bar callouts is performed using the skyline plot values.

For rule set designs, the effects of the Span Detailing Context (other than the skyline plotting) are as shown in the following table.

For the Design Status layer, the effects of the Span Detailing Context (other than the skyline plotting) are as shown in the second table below.

Table 1. Effects of span detailing context on rule set plots
Value	Without span detailing	With span detailing	User provided reinforcement
Top Bottom Top and Bottom	As calculated per section	Values calculated per section are lengthened according to the span detailer rules (see Section 53.1 "Span detailing" of Chapter 53, "Reinforcement Notes") .	Vector component of area of user individual bars intersected by the cross sections
Top Dev Bottom Dev	As calculated per section	As calculated per section	Vector component of developed area of user individual bars intersected by the cross sections
Shear Shear Density Shear Spacing	As calculated per section	As calculated per section	(none)

Table 2. Effects of Span Detailing Context on Design Status Plots
Value	Without span detailing	With span detailing	User provided reinforcement
Top Bottom Top and Bottom	As calculated per section	Values calculated per section are lengthened according to the span detailer rules (see Section 53.1 "Span detailing" of Chapter 53, "Reinforcement Notes") .	Vector component of area of user individual bars intersected by the cross sections
Top Dev Bottom Dev	As calculated per section	Plotted values are the maximum of the reinforcement calculated per section and the amount of developed reinforcement calculated from the span-detailed amounts of non-developed reinforcement (see Section 53.1 "Span detailing" of Chapter 53, "Reinforcement Notes") . These values are used in the final capacity check calculations.	Vector component of developed area of user individual bars intersected by the cross sections
Shear Shear Density Shear Spacing	As calculated per section	As calculated per section	(none)
