This part contains segments with parameters of lateral torsional buckling. It is an optional part of XML file. Every segment is marked by the element <lateralBuckling>. This element supports following attributes:
type | - The direction of considered bending moment. Available values: "my" (LT buckling for moment My), "mz" (LT buckling for moment Mz)
|
start | - The beginning of a segment with web stiffeners. If not defined, the member beginning is considered
|
end | - The end of a segment with web stiffeners. If not defined, the member end is considered
|
length | - The fundamental length for the calculation of lateral torsional buckling. If not defined, the segment length is considered
|
shape | - The shape of the moment area. Available values: "1" - "7" (according to the shape of moment area). The additional attribute "ksi" (ratio between bending moment at the beginning and end, permitted range is <0, 1>) has to be specified for the value "3". The additional attributes "position" (the position of the load, range <0, 1>), "k" and "kw" (available values "jj" joint-joint and "ff" fixed-fixed) has to be specified for values between "4" and "7".
|
use | - The setting which switches on or off the consideration of lateral torsional buckling. Available values: "true" (LT buckling considered), "false" (LT buckling not considered). If not defined, the value "true" is used.
