Beam Section Properties at Last Stage

 

 

 

Once the construction stage analysis is performed, transformed section properties at the last stage can be produced in a tabular format. Transformed section properties including tendons can vary with tendon properties, time of grouting and modulus of elasticity of concrete. Since it produces transformed section properties at the last stage where the changes in construction stages are reflected, we can check accurately what section properties are applied at PostCS (final stage) to calculate stresses due to additional loads such as moving loads and temperature loads.

Elem: Element number

Part: i-end and j-end of an element

Area: Transformed section area

Ixx: Torsional Resistance about ECS x-axis

Iyy: Moment of Inertia about ECS y-axis

Izz: Moment of Inertia about ECS z-axis

Cyp: Distance from the section's neutral axis to the extreme fiber of the element in the local (+) y-direction

Cym: Distance from the section's neutral axis to the extreme fiber of the element in the local (-) y-direction

Czp: Distance from the section's neutral axis to the extreme fiber of the element in the local (+) z-direction

Czm: Distance from the section's neutral axis to the extreme fiber of the element in the local (-) z-direction

WArea: Transformed area for computing selfweight

Section varies with construction stages of tendons as follows:

Construction Stag

Section for computing stress

Section for computing weight

Placing tendons

Net section

Translational Distance: Transfer distance of neutral axis (distance shifted from the original neutral axis to the neutral axis of the transformed section)

Note

The location of the centroid, which is used for determining the distance the neutral axis has moved, is calculated for the section that does not reflect any tendon, reinforcement or Section Stiffness Scale Factor.

 

Local-y: Transfer distance of neutral axis in ECS y-direction

Local-z: Transfer distance of neutral axis in ECS z-direction

Element Coordinate System of a beam element

 

Note

Section Stiffness Scale Factor is not considered in Beam Section Properties at Last Stage" table. In order to check the section properties including the changes due to Section Stiffness Scale Factor, refer to *.out file which is generated after an analysis in the same folder the model file is saved.
