Subbasement Members
Subbasement walls are usually considered as a part of the foundation and provide support for the infills
on the ground storey and contains the fill on the foundation. ProtaStructure 2026 enables the users to
model these walls on foundation level and optionally consider them in the analysis.
Like subbasement walls, subbasement beams and slabs are also considered as a part of the foundation.
They are usually built on top of the fill contained by subbasement walls. Subbasement slabs are
reinforced by mesh reinforcement. ProtaStructure now enables you to model these beams and slabs as
a part of the foundation and mesh them compatibly with neighboring members. Previously it was not
possible to insert and mesh these slabs on top of mat foundation slab (at different elevations).
In the attached document, the modeling, design, analysis and detailing processes for subbasement members in the ProtaStructure are described in detail with tips and tricks.
