ASCE 7's significant changes pertain to calculating wind loads on buildings

The 2010 edition of ASCE 7, "Minimum Design Loads for Buildings and Other Structures," became available in May and replaces the 2005 standard. ASCE 7, issued by the American Society of Civil Engineers (ASCE), provides information that allows designers to determine various types of loads and load combinations on buildings.

The wind load provisions in the new edition have changed dramatically from those in the 2005 publication. In some instances, loads on a given building are higher, and in other cases, they are lower. The 2010 changes are the most significant since the dramatic changes of the 1995 edition. The 2010 edition will be referenced in the 2012 editions of the International Building Code and International Residential Code.

Following is an overview of the additions and changes pertaining to calculating wind loads on roof assemblies only. I do not address changes that only pertain to primary structural elements such as beams, columns, shear walls and diaphragms that provide support and stability for overall buildings.
