BS 8110/EC2 specific options
| Setting | Description |
|---|---|
| Rail Layout Pattern | Controls the layout of the primary rails around a column. The cruciform layout selection will provide parallel rails along each column face and a diagonal rail in each corner. The radial layout selection will provide rails that are radial from the punch check center. Note that for columns with small dimensions it is possible for the layout selection to produce identical layouts. |
| Apply supplemental max stress limit | This option provides a supplemental maximum stress limit on the basic control perimeters as suggested in the paper "Effectiveness of punching shear reinforcement to EN 1992-1-1:2004" in The Structural Engineer 87 (10) May 2009. |
| Reinforcement Ratio | For specification of ρ1 for equation 6.47. You should calculate the input value using the equation in clause 6.4.4 of the EN 1992-1-1:2004 code. This value is only used if the Auto Calc Reinforcement Ration option is not specified. |
| Auto-Calc Reinforcement Ratio | Automatically calculate the ρ value used in equation 6.47 using the user reinforcement on the specified face. Program reinforcement is not used in this calculation. See the notes on auto calculation of ρ1. |
| Bar Location | Specifies the user bar location (top or bottom) to use in the auto calculation of reinforcement ratio. |
| Beta Factor | This represents a ratio of the maximum stress on a critical section (including shear and moment transfer) over the maximum stress due to shear only. This option allows the user to select Auto Calc, 1.15 (interior), 1.4 (edge), 1.5 (corner), or input any positive value for Beta directly. The factors for each column condition are taken from clause 6.4.3 (6) of the EN 1992-1-1:2004 Code and are meant to be used only when lateral stability does not depend upon frame action and where adjacent spans do not differ in length by more than 25%. Auto Calc uses the model and calculation methods described in Chapter 66, Punching Shear Design Notes . |
