Definitions

Load

It should be understood as a structural burden that should be included in the calculation of the mechanical elements (forces, moments, deformation, displacements) of the structure as a system and/or the elements that compose. The structural loads are generally classified as: dead loads acting continuously and without significant changes, belong to this group the weight of the structure, thrusts of liquids (as in a dyke) or solid (such as the floor in a retaining wall), tensor (as in Bridge), presfuerzo, permanent seats; Live loads that are those that vary its intensity over time by use or exposure of the structure, such as the transit bridges, changes in temperature, machinery (such as a press), accumulation of snow or hail, etc; accidental loads that have their origin in actions outside of the use of the structure and whose manifestation is short-lived as they are the seismic or wind gusts.

Stresses

"Stress" measures the average force per unit area of a surface within a deformable body on which internal forces act, specifically the intensity of the internal forces acting between particles of a deformable body across imaginary internal surfaces.[4] These internal forces are produced between the particles in the body as a reaction to external forces. External forces are either surface forces or body forces. Because the loaded deformable body is assumed to behave as a continuum, these internal forces are distributed continuously within the volume of the material body, i.e. the stress distribution in the body is expressed as a piecewise continuous function of space and time.

Slip joints

Slip joints can be designed to allow continuous relative motion of two components or it can allow an adjustment from one temporarily fixed position to another. Examples of the latter are tripods, hiking poles, or similar telescoping device. The position is fixed using a clamping mechanism based on a cam, a set screw or similar locking mechanism. Slip joints can also be non-telescoping, such as the joints on some older wooden surveyor's levelling rods. These use a joint that keeps the sections offset from each other but able to be slid together for transport.

Shear or tensile movement

A shear stress, is defined as the component of stress coplanar with a material cross section. Shear stress arises from the force vector component parallel to the cross section. Normal stress, on the other hand, arises from the force vector component perpendicular or antiparallel to the material cross section on which it acts

Internal stress

In continuum mechanics, stress is a measure of the internal forces acting within a deformable body. Quantitatively, it is a measure of the average force per unit area of a surface within the body on which internal forces act. These internal forces arise as a reaction to external forces applied on the body. Because the loaded deformable body is assumed to behave as a continuum, these internal forces are distributed continuously within the volume of the material body, and result in deformation of the body's shape. Beyond certain limits of material strength, this can lead to a permanent shape change or structural failure.

Injection technique

DESCRIPTION

• Specially for use with Injection mortars FIS V, FIS VS, FIS VW or FIS VT in non-cracked concrete.
• The anchor rods are also suitable for push-through installation, using special push-through elements.
• The mortar bonds the entire surface of the anchor rod to the wall of the drilled hole and largely seals the hole.
• Anchor rod made of stainless steel of the corrosion resistance class III e.g. A4 for outdoor use and in damp conditions.

Advantages/Benefits

•  High-performance mortars allow high loads in non-cracked concrete.
•  various setting depths for different load levels and useful lengths.
•  Quick manual installation without a setting tool reduces the work involved.
•  Simple and quick push-through installation reduces installation time.
•  Steel grade 5.8 or A4-70 guarantee the highest steel load-bearing strength and maximum permissible bending moments.
