Preliminary Study of Past and Present Minimum Load Design Requirements for Wood Frame, One- and Two-Family Dwellings Located on Hurricane-Prone Coastlines with Emphasis on Load and Resistance Factor Design

Abstract:

This research examines the minimum load requirements published by the American Society of Civil Engineers and the Structural Engineering Institute, ASCE/SEI, with respect to wood frame, one- and two-family dwellings along hurricane-prone coastlines; emphasis is on ASCE/SEI 7-02 and ASCE/SEI 7-10 editions of Minimum Design Loads for Buildings and Other Structures. Using wind pressures calculated from the different ASCE/SEI standards and load combinations from the Load and Resistance Factor Design, LRFD, two alternate sets of structural components were designed for a residential structure in Hancock, MS. In addition, a third design set was created based on more conservative parameters. Analysis of each design is performed using finite element software, VisualAnalysis, and assumes various parameters based on progressive failure and lowered material strength properties.
