Structural design: what sazeh checks and what it does not
sazeh is built for moment frames of concrete and steel buildings. This page says which type of structure is within its scope and which is not, so that before you upload a model you know whether it is of use to you.
Concrete structures
Intermediate and special reinforced-concrete moment frames are checked against the reinforced-concrete code. The checks are: flexural reinforcement and shear of the beam, axial-flexure interaction of the column, biaxial interaction, column shear, stirrup spacing in the critical zone, torsion, strong column and weak beam, and amplification of the moment of a slender column. The in-plane shear of the wall, the wall flexure and the boundary element are checked as well.
Steel structures
Intermediate and special steel moment frames with IPE beams and box columns are checked against the steel code. The checks are: compactness, flexure, shear and torsion of the beam, buckling and axial-flexure interaction of the column about two axes, local buckling of the box wall, and the second-order effect. Steel connections are not designed.
Comparing a concrete and a steel design
From one grid a concrete, a steel and a composite design can be built, each checked against the same codes, and their final weight and their volumes of concrete and reinforcement compared. The choice among the designs is the engineer's.
A handout or a PDF book on structural design
sazeh is not a textbook. Its output is the calculation sheet of your own project, delivered as A4 pages that can be printed or turned into a PDF. Because every number of the sheet carries the clause number beside it, the sheet is useful for following the chain of calculation in a real example.
What sazeh does not check
| Type of structure | Status | Reason |
|---|---|---|
| Sheds and industrial structures | Not covered | A shed is a pitched frame with variable members, wind load and cranes; sazeh knows only the moment frame of buildings and does not apply wind load. |
| Shoring structures and trussed shoring | Not covered | Excavation and soil pressure are outside the scope of the service. |
| Light steel frames (cold-formed) | Not covered | Cold-formed sections and their rules are not implemented. |
| Timber structures | Not covered | The code and the material of timber are not implemented. |
| Foundations, slabs and steel connections | Not covered | They are not part of the present version. |
