Analysis and Design of Masonry Structures in Seismic and Non-Seismic Areas
POR 2000 is a powerful Windows application for structural analysis of masonry-built structures subject to seismic and non-seismic actions.
It allows the controls foreseen by the regulations in force for the evaluation of static safety and for the definition of strengthening work. It represents the natural evolution and the increased potency of the Por 98 code. By means of simple operations, it allows the specialised input to structural typologies, an accurate definition of the geometry and mechanical characteristics of the structure and of the strengthening elements.
POR 2000 does not require additional modules. It is distributed in CD-Rom, together with help files, auto-installation program and manual in PDF format.

Why Coosing POR 2000?
For the simplicity of input (user-friendly interface) - The graphic input -that allows Dxf import- and the numeric input -with synchronised grids- create a simple and efficient working environment, that allowsusers to exploit the advantages of both systems and to complete the definition of the structure in a very short time.
For the high level of detail during the structural definition - With Por 2000 users can define structures in a high level of detail. The masonry can be ordinary or rei and the mechanical parametres can be set independently or derived based on correlations available in literature. On the wall panels it is possible to apply transversal misalignments, curbs and various types of reinforcement. It is possible to define lowered ceilings, sloping floors and tie rods between opposite panels.
For the reliability of the seismic modeling - The modeling assumes the MASCHI MURARI as resistant elements, being considered shear-type and with shifts in plant describable by rigid roto-translation. The validity of these assumptions stems from the building box-like behaviour, that determines inflections with void rotations and a strong torsional stiffness of the wall box. For this reason these assumptions have a wide-range applicability. In contrast, a seemingly more sophisticated modeling -that considers separate walls treated as frame structures- would neglect the effects of evrything related to the torsional rigidity of the wall box, thereby losing the most important aspect of the behaviour of the structure.
For the completness of the framework of cheks and the graphic summary - Por 2000 makes a complete framework of cheks, either for local mechanism, or for global ones, evaluated with the seismic pushover analysis. The numerical and graphical summary of results (pushover curves, domain strenght, maps of engagement) effectively represent the static and seismic response of the building and allow you to identify the areas of greatest weakness. Furthermore, these prove very useful for the design and the arrangement of the reinforcements.
Structural Modelling
Por 2000 adopts a sophisticated structural modeling, that includes:
- Definition Wizard for ordinary and armed masonry
- Deformable cutting off and flexural Maschi murari
- Homgenization of the flexural rigidity of seven contact
- Contribution of stiffness due to the sections of the floor
- Contribution of stiffness due to staggered foundations of basements
- Contribution of rods and curbs to checking connections
- Contribution of reinforcements achieved by iniection of mortar, armed plaster, fiber-reinforced materials in carbon or glass, active systems of tie-beaming
- Automatic detection of unsafe structural situations
- Nonlinear pushover analysis for earthquake in variable direction
The program provides an immediate graphical interpretation of the results obtained:
Pushover curves: also called capacity curves, represent the load-displacement balance path of the pushover analysis for each seismic direction and point out the limit states achieved and the safety margins available.
Resistaince domains: they are polar graphs that summarize the verification results for all the analyzed seismic directions, allowing the comparison between acceleration capacity on ground and the corresponding demand.
Seismic committment maps: they are intensity coloured maps that represent the deformation state of the MASCHI for each limit state of inerest (Sld, Slv, Slc) and allow the identification of MASCHI in criticalcollapse.
Verification committment maps: intensity coloured maps that represent the engagement of the single MASCHI in the local verifications.
Reliability for over 25 years
Por 2000 is a structural software (specific for the analysis of masonry buildings) highly optimized, user friendly intuitive even to designers not familiar with computer tools. The ease of the input and the immediate feedback along with the speed of analysis allow a rapid examination of several design variants, encouraging a better and more responsible design.
