Camber Criteria

The Criteria > Camber command is used to define the camber criteria for beam deflection calculations.

Camber can be suppressed by selecting either the Do Not Camber option or the Do Not Camber Beams with span less than option.

Note: This does not mean that for a particular beam camber is not required, just that that no camber will be calculated and considered in the deflection checks.

The indicated percentage of the total dead load is used to calculate the camber. When the camber is calculated, the value is rounded down to the Increment value specified. If the camber required is less than the Minimum Camber value, no camber is specified for that member. If the camber required is greater than the Maximum Camber value, the Maximum Camber value will be used for that member. Note that this does not necessarily mean that larger camber is not required (greater than the Maximum value), it merely means that the amount of camber called out will be limited to the maximum. Generally a more appropriate way of limiting the maximum camber is to specify more stringent deflection criteria. The deflection check would then highlight to the user any beams that fail the deflection check and should be deeper (and hence require less camber).
