Test Certificate

(Certified by - Prof. Dr. P.K.ARAVINDAN, (Former Prof. in Struct. Engg. IIT Madras), Principal Consultant, SREE CONSULTANTS, Chennai - 600 042)
We have tested our own design of aluminium frame of vertical and horizontal mullion for the frame work for Structural Glazing.

Design Calculation taken from the weight of aluminium = 27 kN/m3

& the weight of glass = 25 kN/m3
Wind pressure coefficients: (IS:875 part 3)
Wind speed = 50m/Sec.
Design wind pressure = 1.654 kN/m2
From IS:875 Part(3), Cpe-Cpi=1.1
Design Pressure = 1.82 kN/m2
Section properties are checked and the results are:

  • Bending Stress in Mullion = δ =m = 33.95 <86 N/mm2 = Result - Safe. z
  • Check for axial load = 2.14 N/mm2<85 N/mm2 = Result - Safe.
  • Checking for combined axial load and bending = 0.56<1 = Result - Safe.
  • Check for deflection = Permissible deflection=7.20mm - Safe.

END MULLION
The proposed vertical mullion is 36 x 50mm having flange thickness of 2.0mm and web thickness of 2.0mm. The mullion is assumed to be hinged at both ends.
Section properties are checked and the results are:

  • Bending Stress in Mullion = δ =m = 45.93<86 N/mm2 = Result - Safe. z
  • Check for axial load = 1.29 N/mm2<85 N/mm2 = Result - Safe.
  • Checking for combined axial load and bending = 0.41<1 = Result - Safe.
  • Check for deflection = Permissible deflection=7.20mm - Safe.

Design for Horizontal Mullion
Mullion of size 70x50mm having flange thickness of 2.0mm and web thickness of 2.0mm
Section properties are checked and the results are:

  • Bending Stress in Mullion = δ =m = 23.97<86 N/mm2 = Result - Safe. z
  • Check for axial load = 6.78 N/mm2<86 N/mm2 = Result - Safe.
  • Checking for combined axial load and bending = 0.36<1 = Result - Safe.
  • Check for deflection = Permissible deflection=4.8mm - Safe.

Public Safety
We are an excellent record of public safety. The following details can serve as a guide for selection of a suitable safety glass in any our overhead glazing systems. GLAZING HEIGHT ABOVE THE FLOOR LEVEL: 0-5 meters.The glass should be toughened or laminated.
