This thesis aims to show what impact this change from Boverkets structural design rules BKR to the Eurocode will have on the dimensioning of shear reinforcement and the calculation of deformation in concrete beams.
To examine differences between the calculations of deformation, one method from BKR and one voverkets Eurocode 2 is used. If the wind blows from a certain type of terrain towards a different terrain, the wind load remains the same for the first two kilometers of the new type of terrain. All measurements are calculated based konstrruktionsregler the following documents and conditions Sweden: The value of the wind speed vref is selected based on the location of the building.
It is assumed that konstru,tionsregler length and width of the building are twice as long as the height to the ridge of the roof.

The fact that the partial safety factor is not part of the Eurocode equations for determining the shear resistance in the same manner as it is in BKR, also contributes to the difference in the values.
Boverkets Konstruktionsregler BKR 94 design standards. The municipal building committee shall, among other things, assess whether the design requirements are fulfilled.
This reinforcement should be installed along the entire beam, whether it is needed to achieve sufficient strength or not. The form factor m depends on wind direction and the form of the building as presented in the table below and on the next page.
The reason for the introduction of the Eurocode is to try and eliminate trade barriers between member states. The tables of roof dimensions do not take wind load into account.
The results of these calculations are presented in Table 3. Boverket publishes the Swedish building code. The snow load on the roof is defined by the characteristic value skwhich is calculated as the product of the snow load reference value s0 and the form factor m. The biggest change to the rules for structural shear design is the requirement for minimum shear reinforcement in concrete beams. Login LT EN e. Wind kknstruktionsregler on walls.
Then find the value qk in the tables according to the type of terrain and the building height. The distance is larger according to Eurocode compared to BKR. Boverket Boverket drafts mandatory provisions and general recommendations in Boverket’s Building Regulations.
The snow load reference value depends on the location of the building. Eurocode 2 provides a clearer definition of how much deflection can be allowed, it was not supplied in Boverkets structural design rules.
Compared to table 2. These two methods are used to calculate how much a beam deforms at different relative humidity. The effect of wind load on the roof and wall cladding is determined by the form factor and the characteristic value of wind pressure qk.

The municipal building committee The municipal building committee shall, among other things, assess whether the design requirements are fulfilled.
In order to demonstrate the differences in structural design, with respect to shear force, three examples are calculated. Each example is calculated in accordance with three different methods, two taken from BKR and one from Eurocode 2. The regulations you need to konstruktionsregleg and follow depend on what you want to build or alter.
The relationship between the snow load form factor and roof structure is presented below. This is explained by the differences in how the creep rate is determined in the different methods.

The practical significance of this difference is very small; it only emerges in this thesis when the center distance between the shear reinforcements are determined in example tree. Roof without thermal insulation. When you build a building you need bovverkets follow the building code. You can also find general information about accessibility, dwelling design, obligatory ventilation control and about the Swedish regulatory hierarchy. The results in Table 2. Roof with thermal insulation.
