Higher-Order Effects In Biaxial Flexure Of Gfrp I-Section Beams, Zia Razzaq, Faridoon Z. Razzaq

Civil & Environmental Engineering Faculty Publications

A theoretical study of Glass Fiber Reinforced Polymer (GFRP) beams subjected to biaxial bending moments is presented with a focus on the influence of higher-order effects on maximum normal stresses. It is shown that the biaxial bending type of loading causes a dramatic increase in the maximum normal stress for a GFRP beam when induced torsional effects are included. The study demonstrates that the traditional first-order theory can grossly underestimate the maximum normal stress in a GFRP beam. Based on the numerical results presented using a higher-order theory which also accounts for induced warping normal stresses, the maximum normal stress …

Travel Behavior Change And Economic Transition In Gentrified Neighborhoods, Maryam Izadi

LSU New Orleans Theses and Dissertations

Post-industrial cities in the US have experienced social and economic transitions, mostly in declining downtown neighborhoods. This process, known as gentrification, typically involves revitalization that reverses the decline and disinvestment in inner-city neighborhoods. The industrial shift increased the demand for housing near downtown. The employment of college-educated and high-skill workers has been centralized, while low-skilled jobs continue to decline downtown. While the impacts of gentrification on housing and residential displacement is frequently investigated, little attention has been given to its impact on travel behavior change and economic transition, which is the focus of this research.
