Analysis3D is a powerful Finite Element Analysis (FEA) software designed for structural and civil engineering of steel constructions such as trusses or frames. It offers a user-friendly Windows interface, making it easy to use and navigate.

One of the key features of Analysis3D is its extesive library of cross sections, which includes standards from various countries such as the US AISC, UK British Steel, Japan JIS, Eurocode, Australia and New Zealand, China GB, Russia GOST, India BIS and Timber. Additionally, you have the flexibility to expand or modify this library to fit your specific needs. 

Our software also provides the option to calculate and incorporate Wind loads, Snow Loads and Seismic Loads based on different standards like Eurocode and ASCE 7-16. This allows you to asses the structural response under various loading conditions.

Analysis3D supports Nonlinear or 2nd order Calculations, which consider the deformed structure and incrementally calculates the total effect on the structure. This capability is particularly usefull for analyzing complex strucures that undergo significant deformation.

In terms of Structural Steel Design and Optimization, Analysis3D supports several standards including AISC-ASD, AISC-LRFD, BS5950, CISC94 and EuroCode 3.  The software validates the strength of each member and suggests the minimal cross section required to withstand the applied loads. This feaure helps you to improve and optimize all members of the structure for efficient and safe design.

The software allows you to import or export your structure from AutoCad or other 3D graphics software with DXF-files. This facilitates seamless integration  with existing desing workflow. 

In summary, Analysis3D is a feature-rich FEA software for strucural and civil engineering of steel constructions. It offers a wide range of analysis and design capabilities, a user-friendly interface, and supports multiple international standards.
