LEVEL OF THE ISC SECURITY CRITERIA [MAY 28, 2001]

Analysis & recommendations derived from the response of buildings to explosion effects as described in the military manual TM5-1300, the text on structural dynamics from Biggs, and ConWep.

• Exterior glazing is designed for dynamic air-blast loads of 4 psi & 28 psi-msec

• Mullions, frames & anchorage are designed to resist the maximum capacity of the glass

• Balanced design : weakest element (the glass) fails

BLAST DESIGNBLAST DESIGNBLAST DESIGNBLAST DESIGN

2006 DESIGN

SERA ARCHITECTS, INC. ©200911

• Balanced design : weakest element (the glass) fails first and creates a controlled instead of catastrophic failure of the system

• No ballistic or forced entry threats are to be considered for the windows of this facility

Glazing cracks. Fragments enter space & land on floor no further than 10 ft. from the window

• Heat gain for potential reuse

VARIABLES EVALUATED

• Automated shading strategy

• Glass type on internal façade

• Glass type on external façade

• Dynamic shading control in summer to reduce solar gain

• Thermal chimney to vent heat from envelope in summer

• Insulating “blanket” in winter (better U-value)
