(Ebook) Standard Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals with 2010 and 2011 Interim Revisions by Mackillo Kira ISBN 9780521875097, 9781139182034, 9781560513995, 0521875099, 113918203X, 1560513993

These Specifications discuss design criteria for structural supports, including loads, methods of analysis, designs, and general design features. This edition incorporates recent work performed under the National Cooperative Highway Research Program (NCHRP) and state-sponsored research activities. Section 3, “Loads”, includes a metric conversion of the wind map presented in ASCE/SEI 7-05. The basic wind speed map is updated based on a new analysis of hurricane wind speeds and more detailed maps are included for hurricane-prone regions. Design guidelines for bending about the diagonal axis for rectangular steel sections are included in Section 5. The width-to-thickness ratios and the non-compact limit for stems of tees are also specified. The scope of Section 11, “Fatigue Design,” is expanded to include non-cantilevered support structures and the associated fatigue importance factors. The Specifications are based on the allowable stress design methodology and are intended to address the usual structural supports.Included in this electronic edition are the 2010 and 2011 Interim Revisions. Following each chapter the revisions are identified as well as linked throughout the entire book where available. See the "Interim Revisions" sections for a complete list of changes to each section.
