lae |
L-length, A-anchor, E-earthquake, length of anti-seismic anchorage, is suitable for all elements following anti-seismic design. Usually seen as Tal and Cal in actual drawings. (Taldenotes Tension Anchorage Length and Cal denotes Compression Anchorage Length); You can directly input tal or cal, or just input lae, the software will judge automatically to take value of tal or cal according to related settings. |

la |
L-length, A-anchor, length of non-seismic anchorage, is suitable for all elements following non-seismic design. Usually seen as Tal and Cal in actual drawings. (Tal denotes Tension Anchorage Length and Cal denotes Compression Anchorage Length); You can directly input tal or cal, or just input la, the software will judge automatically to take value of tal or cal according to related settings. Note: It makes no difference to input lae or la in our software when there's no anti-seismic design in your country or region, lae is recommended though. |
tal/cal/tl/cl |

lle |
L-length, L-lap, E-earthquake, length of anti-seismic lap, is suitable for all elements following anti-seismic design. Usually seen as Tll and Cll in actual drawings. (Tll denotes Tension Lap Length and Cll denotes Compression Lap Length); You can directly input tll or cll, or just input lle, the software will judge automatically to take value of tll or cll according to related settings. |
tll/cll/lap |

5 |
ll |
L-length, L-lap, length of non-seismic lap, is suitable for all elements not following anti-seismic design. Usually seen as Tll and Cll in actual drawings. (Tll denotes Tension Lap Length and Cll denotes Compression Lap Length); You can directly input tll or cll, or just input lle, the software will judge automatically to take value of tll or cll according to related settings. Note: It makes no difference to input lle or ll in our software if it doesn’t require anti-seismic design in your country or region, lle is recommended though. |

- Basic Concept
Legs of links:
To calculate the links in column and beam correctly, expression of links should comply with the following rules:
For links of beam, just count the vertical bar lines of beam section, as the figure below shows, beam with two links is expressed with 4 legs in the software.
Figure 1 Legs for beam stirrups, Type 1
For links of column, you have to count the vertical and horizontal bar lines of column section, as the figure below shows, column with four links is expressed with 5*4 legs in the software, 5 denotes vertical bar lines and 4 denotes horizontal bar lines.
Figure 2 Legs for column links
For links with same legs but different combination, they are defined as different type to be distinguished, as the figure below shows, the beam with 4 legs is identified as Type 2, while the one in figure 1 is identified as Type 1, so is the same with column element.
Figure 3 Legs for beam stirrups, Type 2
Rebar Layer:
For some element types, such as beam, if there are multi-layer of rebars, the expression of layers should comply with the following rules:
For Top bars expressed as 2T25/2T22/2T20, 2T25 denotes 1st layer top bar, 2T22 denotes 2ed layer top bar, 2T20 denotes 3rd layer top bar;
For bottom bars expressed as 2T20/2T25/2T32, from bottom to top, 2T32 denotes 1st layer bottom bar, 2T25 denotes 2ed layer bottom bar, 2T20 denotes 3rd layer bottom bar;
