Securing the future of masonry and historical structures across the globe. DIANA is used to analyze masonry structures 100-1000 years old, ensuring that future generations can continue to enjoy their architectural artistry and splendor.
Assessment of historical buildings and monuments
Renovation and retrofitting of historical buildings
Masonry structures of often either smaller private dwellings, or larger historic structures representing a country’s history. Whilst iconic historic structures often provide a valuable source of income, and private dwellings are of extreme importance to their owners, there is rarely a large budget to ensure their outlook.
In a non-intrusive way and cost-effective way, DIANA provides a suite of unique analysis capabilities and material models, enabling you to analyse and make recommendations to ensure the future structural stability of these buildings.
Predicting the failure mechanism of masonry structures
Optimized solutions based on the comprehensive masonry models
For historic structures, original construction data is rarely available, there is often a lack of understanding of the materials with which they were built, of the construction sequence, or of events that may have occurred during the life of the structure.
For the analysis of stone, brick or masonry buildings, DIANA provides you with the ability to analyse in detail as a whole, or in part – under standard – or extreme loading, such as earthquakes.
Detailed reports can be easily produced to form your recommendation for a modern masonry structure of just a few years – now subject to additional loads. Or, a historic building which has undergone changes throughout its lifetime – and is likely to incur more in the future.
Dedicated features for the analysis of masonry & historical structures
