In the Standard Practice for Bracing Masonry Walls Under Construction when determining the loads during construction, per Eq. 5.2.3-1, w=0.00256V^2. Per the notation in section 2.1, V=5-second wind gust velocity. Should the wind speed entered in this equation be 40mph (which is a 3-second wind gust) or is there a different 5-second wind gust speed that I cannot find?
Using 40mph and the equation above, yields a wind load of only 4 psf which seems low. This equation does not take into account exposure, height, or importance factor and states is conservative up to 40 feet height in open areas.
Just want to be sure the wind speed to enter into the equation is truly 40mph and if not, what is the 5-second gust speed?
The 40 mph used in 5.1.3 was chosen to allow a 5 mph cushion above the 35 mph when people are required to evacuate the area. If the wall and bracing apparatus is designed for a w of 5 psf then your wind speed could be up to 44 mph. If you want to be sure you need to get the wind speed at the site of the wall. Again the basis of the included design criteria is 40 mph. even if it is actually less you still use the 40. If you believe the wind speed to be higher through historic data or actual measurement then you design for the higher speed such as a w = 6.4 psf is based on a 50 mph gust. No matter what the people are moved at 35 mph.
I hope this helps, if not give me a call.

Longtime building industry leader works to attract workers
Members of the Painter family have been masons since the early 20th Century, and Painter Masonry has operated for 50 years.
The company, which laid bricks and cement blocks for many of the buildings at the University of Florida and other parts of Greater Gainesville, won’t continue for another generation. No family member is ready to continue Painter Masonry’s legacy, and none of the workers have stepped up to take over.
What’s more, it’s harder and harder to find workers who are willing to take on the arduous work of building the future – one brick at a time – in the Florida sun.
Members of the Concrete Coalition of Florida presented at the National Concrete Masonry Association's Town Hall event held on Wednesday, February 13, 2019 at their annual convention in Orlando's Lake Buena Vista resort.
The MAF's ProMasonry Chairman and Board member, Chris Bettinger presented the accomplishments of the Masonry Association. Matt Sitter, president of the Florida Concrete Products Association gave an overview of the FC&PA's BlockStrong program and Jim Painter, Executive Director of the Florida Concrete Masonry Education Council informed the attendees about Florida's state masonry check-off program. Also speaking were MAF program partner, the AIA Florida's executive Director, Vicki Long and Leslie Chapman-Henderson, Federal Alliance for Safe Homes (FLASH), the country’s leading consumer advocate for strengthening homes and safeguarding families from natural and manmade disasters.
