Masonry17  - Verifiche Muratura

Masonry17 è uno strumento utile per il calcolo della rigidezza di un pannello murario e per il calcolo delle sue resistenze rispetto ai diversi meccanismi di rottura 1) Fessurazione diagonale 2)Pressoflessione 3)Slittamento della parete. Fornisce anche le variazioni di rigidezza della parete a seguito della variazione strutturale oppure variazione di rigidezza indotte dall'utilizzo di materiali di consolidamento quali fibre o altro. 

Masonry17 is a tool for TI-Nspire calculator that allows masonry resistance calculation. Based on Italian code D.M. 14.01.2008 Masonry17 provide stiffness variation of a masonry after refurbishment, resistance of three different mechanism: 1) Diagonal Cracking 2) Axial Force + Bending 3) Wall Slip.   

Software molto semplice ed utile soprattutto per indicazioni strutturali veloci. In particolare è possibile valutare l'effetto della variazione di rigidezza apportata da un intervento di consolidamento strutturale. Questo perchè se il consolidamento non apporta un incremento del 15% non si hanno variazioni sostanziali per la struttura dal punto di vista normativo (NTC08).

 

Masonry property can be define by user or using a traditional Italian typology 

Obviously material properties can be define for a specific case and can be related to a surveys campaign.

The property for material are: 1) compression strength 2) tangential strength 3) Elastic Modulo 4) Tangential Modulo.  

Insert the axial force.

 

Insert shear force.

Insert masonry type or insert "0" for the user's material definition. Italian code: masonry property defined in the database are related to LC1 as per NTC08.

Insert safety factor for masonry. Italian code: Insert gamma m as per NTC08.

Insert masonry height for stiffness and resistance definition. 

 

Insert width of masonry for stiffness and resistance definition. 

Insert thickness of masonry for stiffness and resistance definition. 

Insert the type of restrain: "1" for top of wall not restrained and "2" for top of wall fully fix  

The following results are shown: 1) Stiffness 2) Shear resistance for failure mechanism of axial force combine with bending moment 3) Shear resistance for slip mechanism 4) Shear resistance for diagonal cracking mechanism.

 

IQM - Indice della qualità della muratura

Questa semplice applicazione consente di definire dei coefficienti specifici per ogni tipo di muratura atti ad indicarne qualitativamente la resistenza al taglio, nel piano e fuori dal piano principale. I parametri che governano la valutazione sono: 1) Qualità della malta 2) Presenza di diatoni 3) Forma degli elementi resistenti 4) Sfalzamento dei giunti verticali 5) Presenza di filari orizzontali 6) Dimensione degli elementi resistenti 7) Qualità degli elementi resistenti. La valutazione segue rigorosamente le indicazioni presenti in letteratura le quali permettono di ottenere dei valori qualitativi.
