Workflow
A simplified three-step process

Achieve robust design optimization, automatic code checks, and documentation generation in minutes.

1
Create Beam
Specify multi-span spans, detailed material constraints, loading specifications, and structural cross-section properties.
2
Run Design
Compute multi-span loading configurations with OpenSeesPy FEM and optimize structural reinforcement distribution.
3
Download Report
Instantly export complete IS 456 compliance logs, structured BBS tables, and high-fidelity drawings.

⚠ Not just Pass / Fail

When a section fails, OPTIBIM Pro tells you why — and what to do about it.

This isn't a rubber stamp. When shear demand exceeds concrete capacity, the engine flags a genuine diagonal-compression failure, explains why adding stirrups won't fix it, and points to the specific structural change needed — wider section or greater depth.

FAQ
Common questions
Yes. The LSM engine is built strictly to IS 456:2000 clauses — including neutral axis limits, minimum/maximum steel ratios, ductility (brittle failure prevention), and shear stirrup spacing. Audit Studio flags any clause deviation by name.
The Batch Center accepts standard .xlsx files with a predefined template (downloadable from the app). Results are exported as .xlsx and a consolidated PDF report with a cover page and BBS tables.
Absolutely. There are no long-term contracts. You can cancel, upgrade, or downgrade your plan at any time from your account settings. Yearly plans are refunded on a pro-rata basis.
No credit card required for the Free plan. Sign up with your email and start running beam designs immediately — no expiry on the free tier.
OpenSeesPy is the open-source FEM framework powering Analysis Studio. It computes bending moments, shear forces, and deflections for multi-span beams under arbitrary loading — results feed directly into the Design and Audit engines.
The Free tier is designed specifically for students. If you're a faculty member or institution requiring departmental access, contact OPTIBIM directly at optibim.in for a custom academic arrangement.
You get instant access — sign up, pick a plan, and start designing beams right away. Free needs no card; Professional includes a 14-day free trial, also no card required.
