Solar perplexus


I know that I live in the Dorset Riviera, but am I really supposed to believe that the fabulous difference of 16-C on either side of a properly designed and constructed precast concrete member will cause spalling and failure (Solar gain weakens troubled car park beams, NCE last week).

How on earth did we manage to build those buildings in Northern Ontario where outside temperatures were a mere -65-F (-55-C), or in East Malaysia where structure temperatures in the sun could reach 65-C but inside only 25-C. That is what I would call a temperature differential.

Come on NCE, give us information, not fairy stories.
