Fixed-Fixed Beam
Both ends restrained with fixed-end moments and elastic beam response.
Module 5.0
System Response
This module covers the more coupled beam cases where restraint, continuity, and structural interaction change the response compared with a simple one-span member.
Propped Cantilever
Fixed at one end, supported at the other, solved as an indeterminate beam.
2-Span Continuous
Two-span continuous beam with interior-support moments and elastic response.
3-Span Continuous
Three-span continuous beam with four supports and redistributed moments.
Module Scope
- These tools are intended for cases where support restraint or continuity governs the result more than a single closed-form textbook equation.
- They are the strongest fit when the structure is hyperstatic and the load path redistributes into internal supports or end fixities.
- For early validation or quick comparisons, pair this section with the formulas page and the L/360 limit helper.
