A Decision Making Tool For Incorporating Sustainability Measures In Rigid Pavement Design, Neveen Samy Talaat Soliman

LSU Doctoral Dissertations

One of the most important tools in assessing rigid pavement design sustainability (or environmental impact) is a lifecycle assessment (LCA), which may be applied in any stage of a product’s lifecycle from cradle to grave, such as pavements. Although LCA was the focus of much research and codification by organizations such as the International Organization for Standards and the Society of Environmental Toxicology and Chemistry, limitations exist, such as a) LCA is time consuming; and b) the used data may become outdated, inaccurate, biased, incomplete, and/or expensive to use. These limitations are not a deficiency in LCA as a tool, …

Wind Loading On Trees Integrated With A Building Envelope, Aly Mousaad Aly, Alberto Zasso, Girma Bitsuamlak, Alberto Nicola Longarini, Arindam Gam Chowdhury

Faculty Publications

With the sustainability movement, vegetated building envelopes are gaining more popularity. This requires special wind effect investigations, both from sustainability and resiliency perspectives. The current paper focuses on wind load estimation on small- and full-scale trees used as part of green roofs and balconies. Small-scale wind load assessment was carried out using wind tunnel testing in a global-effect study to understand the interference effects from surrounding structures. Full-scale trees were investigated at a large open-jet facility in a local-effect study to investigate the wind-tree interaction. The effect of Reynolds number combined with shape change on the overall loads measured at …

Cone Penetration In Cemented Deposits-A Field Study, Semih Arslan

LSU Historical Dissertations and Theses

Neglecting cementation results in an underestimation of slope stability and pile capacity in design and analysis of geotechnical engineering problems related to cemented deposits. Developing methods to identify and assess the engineering characteristics of cemented deposits is an important subject in geotechnical engineering.

This study is conducted to evaluate the reliability of the prediction schemes proposed by previous investigators through a field study of cone penetration in a cemented deposit and respective laboratory triaxial study on undisturbed cemented specimens. The effect of cementation on cone penetration resistance is investigated through the field study, and the effects of cementation on drained …
