Materials

All the modes of the application (except for the reference ones) require specifying a material the structural member is made of. This can be done by selecting a stone/brick type and grade, together with a mortar type and grade from the drop-down lists on the General tab.

This tab is also used to specify the importance factor, working life of the structure, age of masonry (under one year or over one year), and, in some modes, the construction season (summer or winter).

When the analysis of masonry from hollow bricks is performed according to SP 15.13330.2012 you can additionally specify the void ratio according to Sec. 6.1 of the given design code.

Each group of modes and individual modes have their limitations which are included in their descriptions.

The following limitations are common for all modes:

only solid masonry is considered;
only finished masonry can be analyzed (fresh masonry or masonry that has not gained strength yet are not considered);
top quality masonry (using leveling boards), for the design strength of which the reduction factors are not introduced, are not considered.

Limitations of bricks/stones — bricks/stones of the following types are not considered:

stones/bricks with courses from 200 to 300 mm high, and between 150 and 200 mm;
earth stones;
adobe bricks.

Technology limitations — the following masonry is not considered:

vibrated brickwork;
frozen brickwork;
rubble concrete.

There are mortar limitations: only heavy-weight mortars are used (cement, stiff, with organic plasticizers, with potash admix).

The application considers structural members made from the following materials:

Mortar
regular cement, mineral plasticizers; stiff cement; cement, organic plasticizers; cement, potash added.	General purpose mortar Lightweight mortar of density from 600 to 800 kg/m³ Lightweight mortar of density from 800 to 1300 kg/m³ Thin layer mortar (bed joint from 0,5 to 3 mm)

The button $image\ebx_-1068461429.jpg$ invokes a dialog box containing information on the design properties of the masonry used.

This window enables to obtain the information on the service factors of masonry and to specify conditions for the calculation of the design strength using the respective checkboxes.

You should keep in mind that service factors are the reduction factors for the design strength of masonry.

The title bar of the dialog contains a button, $image\ebx_-988961141.jpg$ , clicking which will open a dialog box for the customization of the units of measurement.

If the considered structure has damages, you have to check the respective checkbox on the General tab to open the Damage tab where you can specify the relevant information.
