Blast-Resistant Doors: Smart Solutions for Critical Structures

Blast-resistant doors are vital safety solutions used in high-risk environments such as industrial facilities, chemical plants, power stations, mines, and the defense industry.

Blast-Resistant Door Design Process

1. Determination of Design Parameters:
Before manufacturing a blast-resistant door, the following blast parameters must be fully defined:

• Blast pressure (in psi or bar)

• Blast duration (in milliseconds)

• Blast type (e.g., sudden blast, prolonged blast, post-fire explosion, etc.)

2. Door Design and Structural Analysis:
Based on the defined parameters, the door is designed. All design work must be conducted in accordance with standards, especially UFC 3-340-02 (“Structures to Resist the Effects of Accidental Explosions”). During the design phase, nonlinear structural analysis is performed to evaluate the door’s behavior under blast loads.
If appropriate analysis methods are not used, unnecessarily heavier door designs may result, increasing costs and compromising functional usability.

3. Anchorage and Mounting System Durability:
It is crucial to analyze not only the door leaf but also its anchorage and mounting systems:

• Anchors must withstand the dynamic loads generated during the blast event.

• The door must remain securely in place during and after loading without detachment.

Note:
SDTECH delivers the blast design, analysis, reporting, and special anchorage designs as a comprehensive package along with its products.
