Camber Criteria for Composite/Non-Composite Beams dialog

This dialog is used to indicate the conditions under which a camber value will be specified for a beam for either composite or non-composite construction.

The Camber Criteria for Composite/Non-Composite Beams dialog opens when Criteria > Camber > Composite/Non-Composite is selected.

The amount of camber required can be reduced or eliminated by specifying a more stringent Deflection Criteria for Initial deflection for Unshored Composite beams, and for Dead Load deflection for Noncomposite and Shored composite beams. This will result in the selection of a deeper and/or heavier beam that requires less or no camber.

The camber criteria may affect the member size selection if the Net Total Deflection controls the design. By limiting or suppressing the amount of camber, the program will select a deeper and/or heavier beam to satisfy the Net Total Deflection criteria.

Dialog Controls

Setting	Description
Do Not Camber	Selecting this option prevents the program from considering camber for the beam. Check the Cantilevers option to prevent the program from adding camber to any beam with a cantilever section, regardless of any other criteria.
Camber Except When…	Camber can also be suppressed by specifying conditions when, if met, no camber is specified. When values are specified as 0.0 for Camber Except When options, those options will not be considered.
% DL Used for Camber	For unshored composite construction, the indicated percent of construction (pre-composite) dead load is used to determine the required camber. For non composite and shored composite construction, the indicated percentage of the total dead load is used
Camber Increment	When the camber is calculated, the value is rounded down to the Increment value specified.
Minimum Camber	If the camber required is less than this value, no camber is specified for that member.
Maximum Camber	If the camber required is greater than this value, the Maximum Camber value will be used for that member. Note: This does not necessarily mean that the program will select a beam that does not need additional camber (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; that causes a larger beam to be selected that does not need as much camber.
