Cross Section Page
General Tab
It consists of 7 columns that describes and defines the parameters used in modeling the Hollow box cross section.
Variable Tab
Consists of a set of a set of expressions for abscissa and ordinate shown in the right side of this table.This expressions are arithmetical terms of constants and defined formulas.
The variation between two points of the table can be entered:
- Constant The ordinate of the table do not vary to the next point.
- inear The ordinate of the table varies linearly to next point.
- Parabolic variation of type 0 The ordinate of the table varies parabolically to the next point. The slope of the curve at the beginning and at the end is set to 0.0.
- Parabolic variation of type 1 The ordinate of the table varies parabolically to the next point. The slope of the curve at the beginning is set to 0.0.
- Parabolic variation of type 2 The ordinate of the table varies parabolically to the next point. The slope of the curve at the end is set to 0.0.
Two options below the drawing will let the user to observe the Variation on the current span or Variation along the entire bridge length.Begin/End excess length are also considered when stations are defined for the first and last span.
