Masonry & Historical

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 new masonry and historical structures 

Masonry structures are often either smaller private dwellings or larger historic structures representing a country’s history. While 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 upkeep. DIANA provides a suite of unique analysis capabilities and material models in a non-intrusive and cost-effective manner, enabling you to analyze and make recommendations for the renovation, retrofitting, and future structural stability of these buildings.

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 analyze 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.

Special features for Masonry & Historical

Meso-level modeling

At meso-level bricks are modeled with continuum elements and joints with interface elements

Bricks
  • Elastic or viscoelastic material
Joints
  • Discrete crack model with or without crack dilatancy
  • Coulomb friction model
  • Combined Cracking-Shearing-Crushing Model
    User Supplied Subroutines

Macro-level modeling

  • Anisotropic Rankine-Hill plasticity model for 2D plane stress, with optional crack rate dependence
  • Multi-directional fixed crack models in combination with shrinkage and viscoelasticity
  • Total-strain crack models
  • Engineering masonry model

Mass & damping

  • Mass density per unit volume
  • Reduced mass density for dead weight correction
  • Distributed mass elements with damping properties for defining non-reflection boundaries
  • Consistent and lumped concentrated translational masses and rotational inertia
  • Viscous or Rayleigh damping
    Structural or hysteretic damping
  • Continuous damping via discrete spring/dashpot elements

Reinforcement modeling
