Bearing in mind the characteristics of the structural organism of buildings, as well as the causes of failure cases, can be inferred, that the methods of action to protect and strengthen damaged or weakened masonry systems can go in two … read on
Systems with a monostructural structural organism
Systems with a monostructural structural organism are distinguished by this, that all main load cells are made of materials with the same physicochemical or very similar properties, form at … read on
A retaining wall reaching the basement wall of the building
In a building with double-layer walls insulated with the method “light-wet ”solution of the contact between external walls and a retaining wall is much easier to implement – thermal insulation of basement walls acts as a dilatation between the structural wall … read on
The method of provisional protection of the structure
A method of provisionally securing or strengthening vaulted ceilings, bows, lintels etc.. construction, as well as flat ceilings, must be derived from the static properties of these elements. Character has the most significant influence on the choice of security measures … read on
