Relevant Inputs
Each calculator asks for the information needed for its stated scope, while keeping the underlying assumptions visible.
About VitraLab
Facade engineering tools for the small details that decide the job.
VitraLab began with structural glass calculations and is growing to cover facade connections, fixings, brackets, aluminium, steel, and the details that carry a design into construction.

Purpose
Not only glass. The facade as a structure.
A facade is not just a pane, frame, or bracket. Load must travel safely through glass, aluminium, steel, screws, bolts, bearings, anchors, and supports. VitraLab brings calculations for these components into one place.
Readable Checks
Outputs should show what governs, why it governs, and whether the design passes.
Defined Scope
From glass panels to fixings and frame components, the focus is usable project calculation.
Big systems fail through small details.
VitraLab is for the engineer who wants those details visible, checkable, and easier to communicate.
Structural glass checks: ULS, SLS, deflection, wind, maintenance, barrier, monolithic, laminated, and DGU output.
Facade context: support conditions, load paths, component forces, and connection details.
Connection checks: screw pull-out, bearing, shear, tension, bolt resistance, and aluminium or steel bearing behaviour.
Results: inputs, assumptions, utilization, and result summaries remain available for review.
Engineering Basis and Verification
Defined scope, traceable methods, controlled software behaviour
VitraLab Engineering prepares and maintains the technical content behind the calculators. Each tool identifies the standard or draft, calculation method, assumptions, and limits that apply to its output.
Technical Basis
Calculation routes identify the applicable standard or reviewed draft and expose the governing actions, assumptions, and engineering result.
Software Checks
Automated checks help maintain consistent calculator behaviour as the application develops. These are internal development checks and do not represent independent verification or certification.
Engineering Review
A qualified engineer must still verify project actions, supports, fixings, serviceability criteria, National Annex requirements, and the suitability of every result.
Engineering Check Coverage
Calculation tools for facade structures
VitraLab covers common glass, fixing, bolt, bearing, and connection calculations used in facade design.
Screws & Fixings
Pull-out, shear, tension, bearing, and combined actions for screws, bolts, and their supporting materials.
Bolts & Plates
Shear, tension, bearing, spacing, edge distance, and allowable resistance checks.
Aluminium & Steel
Local bearing, section behaviour, connection response, and supporting member checks.
Curtain Walling
Stick and unitised facade checks, from member actions to connection details.
Load Paths
Wind, dead load, imposed load, and local reactions carried through the facade assembly.
Reports
Calculation outputs arranged for engineering review, coordination, and design decisions.
