A wind tunnel test report is received from a client. The wind tunnel test procedure adheres to Austrailian Manual (AWES-QAM-1-2001), ASCE7-10 (Chapter C31), and CTBUH (2013) guidelines. The result of the study shows unfactored net pressures for the 50 year return period (i.e. +1.7kPa and -2.1kPa) . Question: In factored load combination, the client is asking to use ASCE7-05 which gives a factor of 1.6xWL. But when I check ASCE7-10 the factor is only 1.0xWL. Which do you think is the appropriate code to use? (ASCE7-10 or ASCE7-05). Thanks
