Modelling Ultra-High-Performance Concrete (UHPC) and Shape Memory Alloys (SMAs) requires custom constitutive laws.
In the past, a structural engineer's primary tools were a pencil, a physical scale rule, and a basic calculator. The process was linear: determine loads, calculate member forces using simplified formulas, and produce 2D engineering drawings. This approach, however, was inherently limited. For geometrically complex or highly loaded structures, simplifying assumptions could be inaccurate and potentially unsafe.
The integration of visual programming environments—such as Grasshopper (for Rhino) and Dynamo (for Revit)—with structural analysis engines has revolutionized geometric exploration.

Replacing traditional wind tunnel testing with highly accurate Computational Fluid Dynamics (CFD) models using Large Eddy Simulations (LES) to map pressure distributions across complex building facades.
Modern building codes are shifting from prescriptive rules to performance-based design (PBD). PBD requires engineers to demonstrate that a structure will perform safely under specific hazard scenarios, particularly earthquakes and blast loads. Nonlinear Time-History Analysis (NLTHA)
