Rectangular Hollow Sections

The Rectangular hollow section are designed according to the Ref.[22] and Ref.[23].

The bolts can only be positioned outside the Rectangular hollow section with internal bolt distance not exceeding width of the section. At least two bolt-rows must be present.

Beam-column connections

The Rectangular hollow section may be used as a connected beam in bolted column-beam connections. For further info see also chapter: "Supported cross-sections".

The normal procedure described in Ref.[32] is followed for the calculation of the connection characteristics.

The rotational stiffness is not calculated due to the lack of theory available.

Splice connections

The Rectangular hollow section may be used in bolted splice connections. For further info see also chapter: "Supported cross-sections".

For the calculation of the tension resistance of each bolt-row, refer to chapter "The design tension resistance".

More info on the calculation of moment resistance may be found in chapter "The design moment resistance" neglecting the compression component resistance.

The rotational stiffness is not calculated due to the lack of theory available.
