دانلود کتاب Significant Changes to the Wind Load Provisions of ASCE 7-10 - An Illustrated Guide

This book focuses on the updates to the wind load requirements of the newest edition of Minimum Design Loads for Buildings and Other Structures, Standard ASCE/SEI 7-10. The wind load provisions have undergone the most extensive revision since the 1995 edition of the Standard. Generally following the organization of the wind chapters in ASCE 7-10, this handy reference briefly summarizes each change to the wind provisions that might affect actual practice or enforcement and then presents the precise wording of the change. The impact of a change is explained in clear, straightforward language accompanied by diagrams, examples, and color photographs and illustrations to enrich the reader’s understanding. Key changes include: Complete reorganization of the wind provisions from a single chapter to six new chapters that are topic specific; New strength design-based (ultimate) wind speed maps; Applicability of the Wind-Borne Debris Regions; Addition of two new simplified methods for buildings with mean roof heights up to 160 ft.; Exposure categories; Refinements to the low-rise method (envelope procedure); Improvements to determination of loads on rooftop equipment; and Clarifications on roof overhang and soffit loads.
