LEAP CONBOX 12.01

LEAP CONBOX by Bentley Systems is specialized bridge engineering software for analyzing and designing cast-in-place reinforced and post-tensioned concrete box girder superstructures. It enables engineers to model single- and multi-cell, multi-span configurations with constant or variable-depth sections; define tendon layouts and construction stages; and perform code checks in accordance with AASHTO LRFD. Previously offered as part of the LEAP Bridge Concrete suite, its capabilities are now available within Bentley’s OpenBridge Designer environment.

Key capabilities:

• Parametric geometry creation for box girders, including multi-cell sections, haunches, skews, and variable-depth profiles.
• Prestressing and tendon management, including draped profiles, jacking sequences, losses, and time-dependent effects such as creep, shrinkage, and relaxation.
• Load definition and moving-load analysis compliant with AASHTO LRFD (e.g., HL-93), with automatic load combinations and checks at Strength, Service, and Fatigue limit states.
• Structural response evaluation for stresses, deflections, shear, torsion, and envelopes across construction stages and the final condition.
• Reinforcement design assistance for slabs and webs, post-tensioning checks, and constructability considerations.
• Comprehensive deliverables, including customizable calculation reports, tendon schedules, quantity summaries, and detailing aids.
• Integration with Bentley’s bridge design workflows, supporting coordinated modeling and documentation within OpenBridge Designer.
