Structural verification of glass, in the cloud
GLASSS is a web application by Maffeis Engineering S.p.A. for structural engineers and façade designers. Model a glass panel (shape, layers, interlayers, supports and loads), run a finite element analysis on our servers and check stresses and deflections against European or American standards. Every analysis produces a detailed PDF report.

Geometry
Choose shape, design the geometry, the curvature, the built up angle and the layers, eventual interlayers and relative material.
Supports
Add support points, edge supports types and spacers.
Loads
Add the load types and build the load combinations, you can set self wight, wind pressure, wind suction, snow, barriers, points, climate and altitude loads.
Options
Set the verification standard and options, review design values and set deflection option.
Analysis
Run analysis and see the results for displacements and stresses for every load combination.
AI result prediction
GLASSS features also a prototype of neural network trained on a large dataset of simple glass configurations. While entirely independent from the FEM, this artificial intelligence quickly estimates stresses and deformations with good order-of-magnitude accuracy, offering a major speed advantage over traditional analysis.
Checks
Check strength and deformation working ratios.
Report

Peer-reviewed algorithms.
The solid-shell finite element methods at GLASSS's core are grounded in research published in the International Journal of Solids and Structures. Not a black box — open science.
Advanced Analyses with GLASSS Pro
Impact test
Prove your glass structures are safe and resilient. Dynamically simulate sudden impacts (knocks, debris, wind) to determine precise failure limits and energy absorption. Optimize safety and meet compliance, effortlessly.
Cold Bending
Design complex, curved glass facades with confidence. Precisely calculate the internal stresses and structural integrity of cold-bent glass, eliminating guesswork and costly physical prototypes. Achieve stunning aesthetics, guaranteed.
Thermal Shock
Predict and prevent temperature-induced cracking. Accurately model stresses from rapid heating/cooling (sunlight/shadow lines) to proactively select the right glass and structural details. Ensure long-term performance in extreme conditions.
Structural Glass (Fins)
Streamline the engineering of all-glass facades. Easily model the load transfer and stability of vertical and horizontal structural glass fins. Achieve a sleek, transparent aesthetic with certified structural data.
