Overview
The Design Result Dialog provides a comprehensive interface for reviewing and managing post-tensioned slab design results.
The dialog consists of four main areas:
Result Control Panel
Live Design View
Design Result Table, and
Action Button Panel.
Result Control Panel
Provides options for controlling the display mode, result type, and filtering conditions used to review design results.
Live Design View
Provides a graphical representation of the Design Strip for real-time verification of span configurations and reinforcement arrangements.
The view displays:
Span lengths and Design Section numbers for each span.
Reinforcement arrangements assigned to each Design Section.
Locations of supporting columns and walls.
Basic top and bottom reinforcement information.
When View Mode > By Span or By Design Section is selected, selecting a row in the result table highlights the corresponding Span or Design Section in the graphical view, allowing users to quickly identify its location within the structure.
Design Result Table
Displays detailed design results in tabular format for each Design Strip, Span, or Design Section based on the selected View Mode.
Results that do not satisfy the design criteria are highlighted for easy identification and review.
Action Button Panel
Provides tools for report generation, reinforcement updates, result export, and model-view synchronization.
The panel also includes controls for selecting or deselecting result table rows before performing follow-up actions.
The dialog window can be resized by dragging the lower-right corner, providing additional viewing space when reviewing result tables containing a large number of columns, such as stress verification results.
