Release Notes

Changes in Version 5.8.0

(Released 17/11/24)

Raft footings have been added to Tribli, allowing the assessment of footings supporting multiple walls and columns
The punching shear perimeter search algorithm has been improved, resulting in fewer erroneous punching perimeters in areas with complex slab geometries
An axis widget has been added to the 3D renderer
Edge length labels are now displayed when dragging nodes
A transfer manager has been added to simplify visualisation and editing of transfer ratios
An updated license tracker has been been added and is available through the Help menu

Changes in Version 5.7.0

(Released 30/07/24)

Strip footings have been added to tribli. Strip footings behave similar to pad footings, but must sit at the base of a wall chain
Pad footings now inherit their geometry directly from the column over, so there is no need to recentre pads when column positions change
BREAKING API CHANGE: Pad footings can no longer be created via the 'level_proxy' class. They should now be created created via a method provided by the 'column_proxy' class.
Added design summary spreadsheet exports for walls and strip footings
Pad footing design now takes the critical shear plane at a distance dv from the column face, instead of d
By default, pad footing moments are now calculated at 0.7a_sup from the column centre. This can be reverted to the column face in Tribli settings
