Structure Designer

Create a new RC or steel revision from a declared layout. Edit saved models in 2D plan.

Grid, storeys & transfer settings

Edit each storey's columns and beam omissions independently. Upper columns must continue from a supporting column below; model transfer structures explicitly.

Column type

Exact grid coordinates

X lines (m, comma separated)Z lines (m, comma separated)

Unequal bays supported. Existing omissions follow their coordinates when lines are inserted or removed. Grid changes apply to all storeys.

Required for global frame, P-Delta, drift and seismic modes. Select the idealization supported by the foundation detail; rotational soil/foundation stiffness is not modelled.

Steel frame definition

Brief ID · engineer

Steel grade · source

Selecting S275 or S355 fills nominal Fy; verify product thickness and mill certificate before design use. Other grades need a declared Fy.

Base restraint

Frame system for Build one

Project basis source

The alternatives button generates all three framing systems. Select only a system whose connection and bracing arrangement is suitable for your project.

Wall bracing bays · current storey

Select the perimeter bays that actually carry wall bracing. X and diagonal alternatives use only these bays; the moment alternative has none.

Declared section properties

Choose a profile to fill A, Iy, Iz, Iw, J and mass. Iw is required for lateral-torsional buckling. The built-in research catalogue is explicitly unreviewed; verify values against the licensed table or manufacturer data before use. Choose Custom to enter a sourced section.

Every profile is searchable by series, depth, mass or required section modulus, and each one states where its numbers came from.

Declared gravity actions and combination

Uniform floor-beam loads

Imposed action category

Combination factors

Combination ID · name

Declare characteristic floor-beam loads where floors exist; roof loads are entered separately below. The selected action category drives a Kenyan EN 1990 ULS/SLS screening envelope on Analyse. Optional hand-entered factors add a comparison combination; wind and seismic actions remain separate declarations.

Roof framing and roof-plane bracing

Roof system

Self-weight

Include member self-weight from the declared section mass

The additional steel weight case is generated once. Floor and roof dead loads above must exclude member self-weight when this is enabled.

Generate complete frame options from this declared plan. Each alternative is an independent, unverified model.

Revision

Issue purpose

Each project keeps its model, build log and conversation. The engineer, checker, revision and issue purpose above print on the drawing title blocks, the calc report sign-off and every DXF sheet — leave the checker blank until someone has actually checked it.

Clear the canvas anytime — load a project to continue where you left off, no AI re-spend.

Engineering Hub vision

Visual design and deterministic calculations for practicing engineers. Build a declared RC or steel model, inspect supported checks in Results, and export its calculation evidence and drawings. Each result applies to its named method and domain. Review the project code edition, National Annex and all applicable remaining checks before issuing a design. Projects are saved in this browser; native project files provide backup and transfer.
