SAP2000

The industry standard for structural analysis

The SAP2000 name has been synonymous with state-of-the-art analytical methods since its introduction over 45 years ago.

Why SAP2000 works for you

Efficient modeling

Handle linear, dynamic, staged construction, P-delta, buckling, and nonlinear analysis without moving between separate tools.

QUICK TIP: SAP2000 and IDEA StatiCa:

How to perform Stiffness Analysis to improve global model accuracy

When performing a global analysis of a steel structure, engineers typically assume connections are either fully rigid or pinned.

While this simplifies the analysis, real-world connections exhibit some flexibility. By accurately determining the stiffness of a joint, engineers can take advantage of this flexibility in some cases, and optimize their designs for weight, utilization, and cost
