This model shows precisely which part of the section is affected by the resultant of a sectional area or a release. The illustration focuses on the interaction between the wall and the ceiling, with the line hinge and line release being the main focus of the analysis. The linked image shows a schematic representation of the transition zone with clearly marked supports and intersections, which vividly visualizes the distribution of the resulting forces. The model helps engineers to validate connection concepts and to accurately capture internal forces.
