EHF settings

The EHF page in the Model Settings dialog box is used to control the percentages of load used for the EHF calculations when working to Eurocodes. The percentages are material independent, which means that the same percentages are used for concrete and steel. The percentages vary depending on the height of the structure and the number of columns in each direction.

Button, command, or option Description

Height of the structure

Allows you to specify the effective height of the structure to be used in the EHF calculations.

Set Default

Sets the height of the structure to the highest construction level.

Number of columns in X direction

In the Eurocode Cl 5.2(5) the calculation of the reduction factor a m depends on the number of contributing members, m.

Valid input for m in the X and Y directions is any whole number from 1 to 1000. The default value is 1 which results in a m = 1.000. If a value of 1000 is entered then a m would reduce to 0.707.

Number of columns in Y direction

Global initial sway imperfections

Displays the calculated alpha values and phi percentages for the above input.
