VersaTube Building System structures are engineered and configured to meet local area ground snow and wind load requirements. Construction must be certified to be eligible for windstorm insurance coverage through TWIA. For the ASCE 7-10 option we used Ch 27 Pt 1 for the Main Wind Force Resisting Design (MWFRS) and Ch 30 Pt 1 for the Components and Cladding (C&C). So use the method or code that you are required to use, or that you feel is the best fit for your structure. Use our Roof Snow Load Calculator to determine your design roof snow loads. Walls are designed to resist uplift and wind loads. 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. has a map for Minimum Ground Snow Loads located at:
