RIB RTslab 21.0

RIB RTslab by RIB Software SE is a specialized application for analyzing and designing slabs and foundation plates. Built on a finite element engine, it helps structural engineers model complex slab geometries, evaluate internal forces, and produce safe, economical reinforcement solutions. RTslab is suited for flat slabs, mat and raft foundations, transfer slabs, and floor systems with openings or irregular layouts.

Key capabilities:

• Efficient modeling of plate and slab systems, including openings, variable thickness zones, drop panels, and column capitals
• Flexible support definitions such as point, line, and elastic spring supports for soil–structure interaction
• Comprehensive loading options, including point, line, and area loads, as well as load combinations
• Linear elastic analysis with clear visualization of moments, shear forces, reactions, and deflections
• Reinforced concrete design with checks for ultimate and serviceability limit states, including flexure, shear, punching shear, crack control, and deflection
• Practical reinforcement proposals and result maps that support detailing and quantity estimation
• Reporting and documentation tools, with options to export results and drawings for collaboration and review
• Integration within the RIB structural ecosystem to support coordinated workflows

With its intuitive interface and focused slab design features, RIB RTslab streamlines the path from concept to code-compliant design and documentation.
