Each tool has its place. Small firms should start with ClearCalcs, while larger companies might need multiple tools like ETABS + SAP2000.

STAAD Pro: Core Features and Uses

STAAD Pro is Bentley Systems' structural analysis software. Here's what it does:

The software packs four main tools that make structural analysis easier:

1. Shape Editor: Creates custom structural profiles
2. Auto-conversion: Transforms physical models into analysis-ready versions
3. Matrix displacement: Handles stiffness calculations
4. 3D modelling: Spots problems before construction

Here's what each version offers:

STAAD Pro works with:

• OpenBuildings Designer
• AutoPIPE
• Revit
• Tekla

What's Good:

• Uses less memory than Autodesk tools
• Makes reports 50% faster (2024 version)
• Imports AutoCAD files directly
• Includes stress testing

What's Not:

• Can't handle brick masonry well
• Has issues with curved edges
• Misses some report details
• Needs expert knowledge for complex jobs

Bentley's £1 billion+ investment shows in STAAD Pro's regular updates. The 2024 version runs faster and fixes known bugs.

2. ETABS: Building Analysis Tools

ETABS is a building analysis powerhouse from Computers and Structures, Inc. (CSI) in California. Here's what makes it stand out:

At its core, ETABS runs on the SAPFire Analysis Engine - a system with 45+ years of testing behind it:

The software packs some serious muscle:

• 64-bit solvers that handle multiple tasks
• Eigen and Ritz analysis options
• Ready-to-use material libraries
• Supports both U.S. and international codes

It plays nice with other software too:

• Links to Revit
• Opens AutoCAD files
• Connects with Tekla Structures
• Works with BIM software

"For High Rise Buildings I would prefer E-tabs only, as the other scope are project situated in earthquake prone zones will be easy to design and analyze the seismic waves with recent input data." - Koushik Ghosh, Executive, Hospitality

The Good Stuff:

• Makes high-rise design a breeze
• Handles complex earthquake analysis
• Shows results clearly
• Gets automeshing right

The Not-So-Good:

• Analysis takes time
• Needs lots of storage
• Can't figure out stair rebaring
• Struggles with stair load distribution

ETABS scores 4.3/5 in user reviews and helps thousands of firms across 160+ countries get the job done. Even the One World Trade Center in New York relied on ETABS for its structural design.
