Analysis of masson and reinforced masson structural elements

The purpose of the program is to verify the load-carrying capacity of structural elements of masson and reinforced masson structures in compliance with SNiP II-22-81 and documents issued to update and supplement these regulations.

Elements to be verified include centrally and eccentrically loaded columns of various plane cross-sections; coursed, Dutch and arch lintels, exterior and interior walls of buildings with or without openings, basement walls.

Together with the general strength and stability verification, elements can be investigated for local strength in places where beams, girders and other parts bear against walls or columns.

These verifications are performed both with undamaged structural parts and with elements that have fractures in their stonework or fire damages caused by temperature. Damaged structures are verified using provisions of the document "Recommendations on reinforcement of structural masonry. Kucherenko Central Research Institute for Structural Constructions, USSR State Committee for Construction".

Another object of verification is the load-carrying capacity of centrally and eccentrically loaded members reinforced by steel hoops, and walls weakened by additionally introduced openings.

The operation modes of the program can be divided into four groups: three of them perform an expert investigation (Masson constructions, Reinforced masson constructions, Renovated constructions) and the fourth one is for reference (Reference mode).

Masson constructions

Modes of this group are intended to investigate individual structural parts of stone constructions. In the present version these parts include: centrally compressed posts, eccentrically compressed posts, exterior wall of a building, basement wall, lintels; also, the local strength is verified.

Reinforced masson constructions

Modes of this group are intended to investigate individual structural parts of reinforced masson constructions. These parts include: centrally compressed reinforced posts, eccentrically compressed reinforced posts, a reinforced exterior wall of a building, reinforced basement wall; also, the local strength of reinforced constructions is verified.

Renovated constructions

Modes of this group are intended to investigate individual structural parts of stone constructions that include damaged elements reinforced by steel hoops. In the present version these parts include: centrally compressed posts reinforced by hoops, eccentrically compressed posts reinforced by hoops, hoop reinforcement of a building's wall, wall opening.

The reference information contains specific volume weights of masonry made of bricks, natural or artificial stones on heavy mortars, and also data regarding a classification of masonry damages.
