Stripping and handling contains four optional stages for stripping, handling, erection, and a secondary erection. The face lifter input and top edge lifter input do not change the analysis results, only modify the model and reported reactions. Their inputs are:
Header | Description |
|---|---|
Columns of Lifters | Number of lifting devices at each lift point, and is used for calculating lifter forces and for the 3D drawing. |
Top in Form | Select from Bottom, Top, Left, or Right Face for the top in form face. |
The four optional analysis stages contain the following options:
Header | Description |
|---|---|
Face Loops | The quantity of face loops on the member. |
Dunnage Points | The quantity of dunnage points on the member. |
Load Multiplier | A multiplier to be applied to all self weight. |
Lift Type | Static Lift: Will assume all lift locations act as a pin. Rolling Block: Will assume a sling is run between sets of connectors. This sling normalizes forces between connectors. The forces are normalized between for an entire crane line. For example, if doing a 4-high lift using 2 crane lines, the first two lifters will have the same reaction and the second two lifters will have the same reaction. Where if one was doing a 4-high lifting on a single crane line, all 4 lifters would have the same value. |
Tilt Angle | The angle to tilt the member for the analysis. |
Concrete Strength | Option to use either the release strength or the 28-day strength of the concrete. |
Stress Limits | Option to use either the handling stress limits or the in-place stress limits. |
Sling Angle | Angle used to compute the lateral force at a given lifter. This value will not effect the analysis and will only be used to estimate the shear force a connector is exerting on the panel. |
Add Ground Reaction | Option to add an a ground reaction on the member. If the ground reaction ends up being negative (in tension), consider removing the ground reaction. |
