This is explained by the differences in how the creep rate is determined in the different methods. In order to demonstrate the differences in structural design, with respect to shear force, three examples are calculated. Go to the page menu Go to the page content. These two methods are used to calculate how much a beam deforms at different relative humidity.

Eurocode 2 provides a clearer definition of how much deflection can be allowed, it was not supplied in Boverkets structural design rules. Later, in conjunction with the technical consultation and start-up statement, the building committee shall deal with the technical property requirements regarding dwelling design and other technical property requirements.

Then find konstruktionsrgeler value qk in the tables according to the type of terrain and the building height. Boverket Boverket drafts mandatory provisions and general recommendations in Boverket’s Building Regulations.

To examine differences between the calculations of deformation, one method from BKR and one from Eurocode 2 is used. The partial factors method is applied. Form factor maximum values are specified below in roof schemes according to the roof slope. The municipal building committee also has supervisory responsibility for the building works.

Taking into account the requirement of minimum reinforcement, table 2. The reason for the introduction of the Eurocode is to try and eliminate trade barriers between member states. Wind load pull — self-weight. It is assumed that the length and width of the building are twice as long as the height to the ridge of the roof.


The regulations you need to know and follow depend on what you want to build or alter. Boverkets Konstruktionsregler BKR 94 design standards. This reinforcement should be installed along the entire beam, whether it is needed to achieve sufficient strength or not.

The value qk is determined based on the reference wind speed vref, the type of terrain, and the height of the building.

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 form factor m is used for calculating the dimensions of the cladding. The load reduction factor Y is found in the following table.

The municipal building committee shall, among other things, assess whether the design requirements are fulfilled. If the wind blows koonstruktionsregler 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. Form factor m is used for selecting the fixing elements of roofing and determining their dimensions.

The tables of roof dimensions do not take wind load into account. Wind load on walls. Boverket publishes the Swedish building code. Please use this url to cite or link to this publication: All measurements are calculated based on the following documents and conditions Sweden: 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 konstruktionsegler of deformation in concrete beams.

The results boverkwts these calculations are presented in Table 3. The form factor m depends on wind direction and the form of the building as presented in the table below konstruktionsreglef on the next page. 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 boveroets the values.


The information presented is suitable for single and double pitched roofs. The building code in Sweden contains mandatory provisions and general recommendations. 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.

When you build a building you need to follow the building code. The snow load reference value depends on the location of the building. konstruktionsreyler

The form factor is increased in shadow zones. The relationship between the snow load form factor and roof structure is presented below. The distance is larger according to Eurocode compared to BKR. The municipal building committee The municipal building committee shall, among other things, assess whether the design requirements are fulfilled.

Roof with thermal insulation. Compared to table 2. Roof without thermal insulation. The value of the wind speed vref is selected based on the location of the building. The biggest change to the rules for structural shear design is the requirement for minimum shear reinforcement in konstruktionsregle beams. You can also find general information about accessibility, dwelling design, obligatory boverkes control and about the Swedish regulatory hierarchy.

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. If both the length and width of the building are twice as long as the height of the roof ridge, the fixing elements must be selected by taking bovedkets account the tensile load in proportion to the following form factor values.

Each example is calculated in accordance with three different methods, two taken from BKR and one from Eurocode 2. The results in Table 2.
