24 * Brick material definition is available for //Plane wall// objects only.
25 * The effect of mortar on design can be considered in two ways:
26 *1. In case of "masonry unit (brick) only"-type //Brick //library materials //Mortar strength//, //Constants// according to EN1996-1-1 (3.1-3.4) and calculation method of //Modulus of elasticity// can be set in //Application data //dialog.
27 *1. In case of "masonry (brick + mortar)"-type Brick library  material no extra settings are required from //Application data// dialog.

37 Masonry design calculation is carried by vertical //Wall //stripes. The stripes help to accurately account for the openings, the load / support / slab-connection conditions of a wall, which may vary along the length. The stripe-division is performed automatically based on the //Default //(maximum) //stripe width //parameter that we specify at //Configure masonry design//.

44 (((
45 * The recommended maximum stripe size is 1-2 meters.
46 * FEM-Design generates stripes of the same width for wall parts without openings.
47 * By default, FEM-Design does not take into account the wall parts (and so the stripes) below and above the openings, it sets them as "Not relevant" to the design. These parts are marked with a black cross.
48 * A stripe can only be a quadrilateral (most often a rectangle) or a triangle depending on //Wall //geometry.

55 Stripes can be modified one-by-one manually with the tools of// Calculation parameter//: //Split stripe//, //Move border// and //Merge stripes// (to one). The behavior and the properties of a stripe can be set with the //Properties //function:
56
57 * By //Not relevant// it can be set whether or not ("Not relevant") a particular stripe is taken into account in design
58 * //Slab-wall connection //(hinged or rigid) influences moment distribution by eccentricity between a slab and the wall part.
59 * //Layout //defines how a slab is positioned above/below the wall part.
60 ** //d1, d2 //are// //needed to calculate the free height of the wall part.
61 ** //s1, s2 //are// //needed to calculate the moment due to slab eccentricity.
62 * Modified stripes can be restored to the state and size recommended by FEM-Design (from the automatic generation and the //Default //(maximum) //stripe width //parameter) with the //Reset wall stripes// command at any time.
