Design speci cations for wind loads on low-rise structures still rely on reductive tables and plots that can over-simplify the highly complex nature of wind-structure interaction. The need for simpli ed information and design procedures stems in part from the limited information capacity of the current generation of design standards. The purpose of the(More)
Teens who have viewed alcohol-related content on social networking sites are more likely to have consumed alcohol than teens that have not seen such content. This suggests a rising concern about the influence of these sites on adolescent drinking behavior. Parents, health organizations, and school administrators need a deeper understanding of online(More)
Standard provisions for wind loads on buildings have traditionally been based on summary tables and/or plots suitable for slide-rule calculations. The accuracy in the definition of wind loads inherent in such tables and plots is far lower than that inherent in current methods for stress computation. Advances in computational power now make it possible to(More)
Following such landmark aerodynamic tests as Irminger’s in 1894, Flachsbart’s in 1932—the first to be conducted in boundary-layer flow—and University of Western Ontario (UWO) 1970s tests, considerable progress has been achieved in low-rise building design for wind. Nevertheless, the present state of the art remains inadequate. UWO tests were conducted at(More)
For the estimation of probability distribution parameters, the method of self-determined probability weighted moments (SD-PWM) has previously been introduced as a refinement on the original method of probability weighted moments (PWM). Tables have been created summarizing the solution of the relevant equations for certain probability distributions, but(More)
The growing number of highway bridges in poor condition requires the development of effective tools for inspecting and evaluating bridges. To address the limitations of current assessment practices, a new nondestructive evaluation methodology, incorporating global and local evaluation techniques to obtain a quantitative assessment of the structural(More)
Standard provisions for wind loads on buildings have traditionally been based on summary tables and/or plots suitable for slide-rule calculations, leading to a discrepancy between the accuracy of wind loads defined by such tables and plots and the accuracy of current methods for stress computation. Advances in computational power now make it possible to(More)
For the estimation of probability distribution parameters, Haktanir (1997) introduced the method of selfdetermined probability weighted moments (SD-PWM) as a refinement on the original method of probability weighted moments (PWM) defined by Greenwood et al., (1979). Tables have been created summarizing the solution of the relevant equations for certain(More)
