Steel spiral staircases provide an elegant and space-saving solution for vertical access in buildings. Due to their curving design, they seamlessly integrate with modern architecture while providing a strong and durable structure. Versatile and adaptable, spiral staircases are ideal for both indoor and outdoor areas.

In the ultimate configuration of the steel joint design, you have the option to modify the limit plastic strain for welds.
Using the "Base Plate" component, you can design base plate connections with cast-in anchors. In addition to plates and welds, the design analyzes the anchorage and the steel-concrete interaction.
In the "Edit Section" dialog box, you can display the buckling shapes of the Finite Strip Method (FSM) as a 3D graphic.
- Design of five types of seismic force-resisting systems (SFRS) includes Special Moment Frame (SMF), Intermediate Moment Frame (IMF), Ordinary Moment Frame (OMF), Ordinary Concentrically Braced Frame (OCBF), and Special Concentrically Braced Frame (SCBF)
