  • Answer

    DSTV is used to compare existing internal forces with the allowable values of the German guideline DSTV so that you can determine the required joint from typified connections. On the contrary, END‑PLATE is used to recalculate the entire connection.

    The connections in END‑PLATE can be extended on both sides and four bolt rows are also possible.

    DSTV includes not only bending-resistant end-plates but also hinged end-plate and angle connections.

    Thus, the main differences are:

    In addition to the rolled sections (I, IPE, HE‑A, HE‑B, HE‑M), the END‑PLATE add-on module allowsw for design of any monosymmetric I-section with axial force (IS- and IU‑sections). In contrast, the DSTV guideline gives only values for the common rolled sections (IPE, HE‑A, HE‑B, HE‑M) and the values calculated are allowed only for bending with shear force, which means that the axial force is not considered in the DSTV guideline.

    To design a HD‑section on end-plates, for example, you can use END‑PLATE and replace the HD‑section by an IS-section.

    In the case of IS‑sections, you can graphically select the dimensions of the HD‑section. Thus, this IS‑section has the same stiffnesses and can be designed in END‑PLATE.

    This message appears if the guidelines are not met for the dimensioned end plate.

    Primarily, the recommendations for the layout of welds are supposed to be a design aid, so they are no binding requirement.

    Welds can be carried out even bigger if adequate methods are applied.

    But if you want to keep the limits, go to the input window 1.2 and select the option for entering the end plate thickness dp. If you enter the dimensioned thickness there, you can see the limits according to DIN in the results table for the weld design.

    Now, if you select a value for the web weld that lies within these limits and you restart the calculation, no error log will occur.
