Now coming to main structural analysis part, these provide different calculations on static analysis non-variable load , eigenvalue analysis, static pushover analysis, static adaptive pushover analysis, static time-history analysis, dynamic time-history analysis, response spectrum analysis, incremental dynamic analysis, and more.

The result report can be easily fetched for interpretation. The reports basically consist of calculations on joint reactions, joint deflections, story drift, member forces, member stresses, member torsion, suggested design, plate stresses, material takeoff, solid stresses, solid principals, connection results, etc.

One of these is a bridge structure analysis software which can be used to create railway or highway types bridges and analyze the created bridge structures for their credibility. SeismoStruct is one of my favorite structure analysis software.

It provides a wide range of tools in order to analyze structures. You get results including step output, deformed shape viewer, action effects diagrams, global response parameters, element action effects, and stress and strain output. But, it is free for academic users for educational purpose only. LinPro is another good structural engineering software.

It is easy to understand and hence, is recommended for the beginners. SeismoStruct is a free structural engineering software for Windows. Although it is a paid software and comes in a day trial version, students can obtain an academic license to use it for free.

It basically consists of three main working modules including Pre-Processor , Processor , and Post-Processor. Other features of this structure engineering software include creating an analysis movie AVI , inbuilt calculator, SeismoBatch batch executing saved projects , and more.

The GNU Octave project began with good intentions as a more flexible tool for students to learn chemical engineering by providing solutions for chemical reactor design problems. It is now a widely used language and software package by educational organizations, students, and commercial operations. Feature list — solve common numerical linear algebra problems, finding the roots of nonlinear equations, integrating ordinary functions, manipulating polynomials, and integrating ordinary differential and differential-algebraic equations.

The R-project is also a GNU project that focuses more on statistical computing and graphics rather than scientific numerical computing. R is also an open sourced language and software package meant to be used for data manipulation, calculation and graphical display. Although it is advertised as and widely viewed as a statistical mathematics software package and language, the R environment can be used for scientific analysis and broad numerical computing.

Feature list — effective data handling and storage facility, suite of operators for calculations on arrays and matrices, intermediate tools for data analysis, graphical facilities, well-developed programming language. Their software packages can be selectively purchased to make sure you are only paying for exactly what you need. The SolidWorks CAD package boasts inclusion of design, simulation, cost estimation, manufacturability checks, CAM, sustainable design, data management, and material insights.
