What happens here

This critical demonstration highlights the consequences of omitting a header. The header is removed from the framing model, leaving the opening unsupported. When the same hydraulic load is reapplied to the structure, the framing immediately and rapidly fails. The top plate and cripple studs buckle and collapse into the opening, dramatically illustrating the indispensable role of the header in maintaining structural integrity and preventing catastrophic failure of the wall above an opening.

Goal: Understand the critical consequences of omitting a header.

Tools and materials

  • 4 Ton Porto Power Jack Porto Power Jack — To apply simulated structural loads
  • Framing Demonstration Model — To show structural failure under simulated load
  • Pressure Gauge — To measure the applied load, though its reading is not specifically discussed
  • Header Piece Custom-made — Removed from the model to demonstrate structural failure without its support

What they say

Hide

load with a header. As you see here, deflection of the top plate is assisted by this header here, transferring the weight down into the footing. Let's see what happens when loads are applied without a header.
