When building a structure it is important to calculate wind load to ensure that the structure can withstand high winds, especially if the building is located in an area known for inclement weather. THE MASSACHUSETTS STATE BUILDING CODE 272 780 CMR - Sixth Edition corrected - 9/19/97 (Effective 2/28/97) 1611.3 Reference wind velocities: The reference 4 0 obj

The hill, ridge or escarpment is unobstructed upwind by other such topographic features for a distance from the high point of 50 times the height of the hill or 2 miles (3.22 km), whichever is greater. Currently the above wind force software is based on the US, Australia, Canada, select European countries, India, Philippines, and Spain to help engineers determine their design wind and snow pressures for buildings. Supplements and errata are an essential component to the Standard provisions and All previous editions of 7 are available in the ASCE Bookstore. &
