Loading conditions (custom design)

The following parameters are entered separately for each design rectangle. When complete, click “Next Rectangle” (for cases with more than one design rectangle) and finally “Analysis Parameters” when all data entry is complete. Any rectangle may be edited at any stage of inputting.

(Direction 1) – Length (self explanatory)

(Direction 2) – Breadth (self explanatory)

No. beams in direction 1

Number of beams that are parallel to direction 1. If direction 1 is the long direction (typical) then this is the number of long beams.

No beams in direction 2

Number of beams that are parallel to direction 2. If direction 2 is the short direction (typical) then this is the number of short beams.

UDL (kPa)

This is the sum of all uniformly distributed loads applied to the current design rectangle. It may typically include the internal wall loads, plus a roof load in the case of a conventional roof.

Edge Load

This is the sum of all line loads acting along each side of the current design rectangle. It may typically include loads from external walls, and a roof load in the case of a trussed roof.

Centre Line Load

This is an optional line load taken along the centre of the slab in either direction. The Centre Line Load (Direction 1) is considered to run parallel to direction 1, and the Centre Line Load (Direction 2) is considered to run parallel to direction 2.
