Input | Description |
|---|---|
Include Stage | Checking this box will include the corresponding stage for the analysis. |
Load Multiplier | Load multiplier applied to all self weight for the analysis. The load multiplier is not included when checking lifter capacities. |
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. |
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. |
Tilt Angle | The angle to tilt the member for the analysis. The tilt angle is used to change the direction of the applied self weight. It does not change how lifter forces are computed as a more accurate computation requires more data than is provided. Tilt angle is only available when a ground reaction is included. |
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. |
Face Lifters on Single Crane Line | |
Assume top Edge Lifters Carry Panel Weight | This option is used to assume the panel will be held carrying it’s entire weight on the top edge lifters. Checking this option will override the computed tension in the connection to be the panel weight divided by the number of edge lifters. |
