Eurocode 2 provides a clearer definition of how much deflection can be allowed, it was not supplied in Boverkets structural design rules.
The load reduction factor Y is found in the bovwrkets table. The partial factors method is applied. 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.
Swedish Regulations for building works
The results of these calculations are presented in Table 3. The results in Table 2. The practical significance konstrukktionsregler 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. Taking into account the requirement of minimum reinforcement, table 2.
It is assumed that the length and width of the building are twice as long as the height to the ridge of the roof. Boverket publishes the Swedish building code. The reason for the introduction of the Eurocode is to try and eliminate trade barriers between member states. Compared to table 2. 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.
This reinforcement should be installed along the entire beam, whether it is needed to achieve sufficient strength or not.
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 into account the tensile load in proportion to the following form factor values.
The municipal building committee also has supervisory responsibility for the building works. 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. Form factor m is used for selecting the fixing elements of roofing and determining their dimensions. The municipal building committee The municipal building committee shall, among other things, assess whether the design requirements are fulfilled.
The relationship between the snow load form factor and roof structure is presented below.

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 value qk is determined based on the reference wind speed vref, the type of terrain, and the konstruktionsregled of the building. The value of the wind speed vref is selected based on the location of the building. Wind load pull — self-weight. The tables of roof dimensions do not take wind load into account. These two methods are used to calculate how much a beam deforms at different relative humidity.
Please use this url to cite or link to this publication: To examine differences between the calculations of deformation, one method from BKR and one from Eurocode 2 is used. Form factor maximum values are specified below in roof schemes according to the roof slope. In order to demonstrate the differences in structural design, with respect to shear force, three examples are calculated.
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. Boverkets Konstruktionsregler BKR 94 design standards. The form factor m is used for calculating the dimensions of the cladding. Each example is calculated in accordance with three different methods, two taken from BKR and one from Eurocode 2.
The biggest boerkets to the rules for structural shear boverkeets is the requirement for minimum shear reinforcement in concrete beams. The distance is larger according to Eurocode compared to BKR. Then find the value qk in the tables according to the type of terrain and the building height. The information presented is suitable konstfuktionsregler single and double pitched roofs.
Konstrukttionsregler building code in Sweden contains mandatory provisions and general recommendations. 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. This is explained boverketw the differences in how the creep rate is determined in the different methods. Wind load on walls. The snow load reference value depends on the location of the building.
