Chennai Airport Glass breakout ceremony continues

The expansion and contraction of materials must be considered when designing large structures, This may be the reason for 65th time rooftop glass breakout at Chennai Airport international terminal.
Its an large metallic structure without any gap for metals to expand and contract. Glass might be covered with metallic frames due to compression it may burst and break out.

inside the Airport it may be cool below 22 C but out side it will be 45 C . so this difference in temperature may cause some effect on roof top metals.It may have contraction towards glass frames .

Just leave a few gap between metals to expand and contract.fill that gap with Polyethylene sheets or some other plastic sheets .
Just a guess and it might be right
