3.6.5 Shear Joint
In the design according to EN 1992-1-1, it is possible to design shear joints of casting segments, as well as shear forces between beam web and flange.
By selecting the Shear joint available check box, you can activate the design of joints, for example in concrete additions for precast members. The other input fields will be enabled for entering the parameters according to EN 1992-1-1, 6.2.5.
The Location of shear joint must be defined by the distance from the top or bottom side of the plate. Alternatively, it can be arranged automatically between plate and web.
The Surface classification can be selected in the list. EN 1992-1-1, 6.2.5 (2) describes the different surface categories.
If there is Fatigue or dynamic loads, the roughness factors c must be halved according to EN 1922-1-1, 6.2.5 (5). For this, specify the support widths a+y and a-y of the precast elements, as well as the stress σn, if applicable, due to the minimum axial force perpendicular to the joint.
The check box provides the possibility of activating the Design of flange connections on segmented cross-sections.
The [Details] button opens the Details dialog box with general calculation settings (see Figure 4.1). In the Ultimate Limit State tab, you can define the calculation method for determining the shear stress in shear joints, as well as the longitudinal force difference between member web and flange. The theoretical background is described in chapter 2.1.4.
