Strong Column-Weak Beam Check (NBCI-2016)
Summary
Strong Column-Weak Beam Check in ProtaStructure with NBCI 2016
ProtaStructure Suite now fully supports Indian Codes (NBCI), including standards for loading, seismic design, and steel and concrete design. This ensures compliance and precision for engineers working on Indian projects. One critical aspect of structural design in NBCI 2016 Annex F is the strong column-weak beam check, which ensures ductility and safety in seismic design.
Strong Column-Weak Beam Check Process
After completing the building analysis, ProtaStructure automatically checks both global and local ductility conditions. This includes verifying that columns remain stronger than beams at beam-column joints, a key principle to prevent catastrophic failures during seismic events.
The process involves:
- Analyzing Beam-Column Joint Behavior: Ensuring that columns can adequately support the forces transferred by beams during an earthquake.
- Global Ductility Check: Verifying the overall ductility of the structure to withstand seismic loads.
- Local Ductility Check: Ensuring individual joints meet code requirements for deformation and force distribution.
This document provides a step-by-step explanation of these checks through a numerical example of a 4-storey building, illustrating compliance with NBCI 2016 Annex F.
