Histra Bridges

Potente solutore a matrici sparse sviluppato da ricercatori dell'Università di Catania che permette l'esecuzione di analisi statiche non lineari a controllo di forza e spostamento per la valutazione della capacità portante della struttura in condizioni statiche e sismiche.

Lettura facile e chiara dei risultati
La visualizzazione dei risultati è semplice ed intuitiva, dando una chiara visione della risposta globale e locale di ciascuna fibra, mediante opportune mappe di colore in termini di tensioni, deformazioni, deformazioni plastiche, indicatori di danno, sia nelle viste 3D che con grafici 2D di facile lettura. E’ possibile tracciare la risposta in termini di curve di capacità e di linee di influenza del moltiplicatore di collasso al variare della posizione del carico mobile, per individuare quelle posizioni che determinano il minimo valore della capacità portante della struttura. I risultati ottenuti possono essere esportati in tabelle con files formato XLS ed in grafici nei formati standard più comuni.

Histra Bridges

High-performance sparse matrix solver developed by researchers at the University of Catania, enabling nonlinear static analyses under both force-controlled and displacement-controlled procedures for the assessment of structural load-bearing capacity under static and seismic conditions.

Clear and intuitive interpretation of results
Results visualization is straightforward and user-friendly, providing a clear representation of both global and local structural response at the fiber level through dedicated color maps showing stresses, strains, plastic strains, and damage indicators, available in both 3D views and easy-to-read 2D charts.

The software allows plotting capacity curves as well as influence lines of the collapse multiplier as a function of moving load position, enabling identification of the load configurations that produce the minimum structural capacity.

Computed results can be exported as tables in XLS format and as charts in the most common standard file formats.
