Development And Calibration Of A Multi-Zone Model To Predict The Distribution Of Contaminant In A Residential Building Using Contam Software, Magda Nohella Hernandez Ramirez
Development And Calibration Of A Multi-Zone Model To Predict The Distribution Of Contaminant In A Residential Building Using Contam Software, Magda Nohella Hernandez Ramirez
Civil Engineering Theses
The use of computer simulations is a powerful alternative in the Indoor Air Quality (IAQ) study due to the efficient performance and the amount of it is able to obtain. Multi-zone modeling is one of the most popular computing methods for IAQ study, thus can provide the knowledge of indoor airflow, temperature and contaminant concentration distributions. The study was conducted in TX Air House 1 using CONTAM software developed by U.S. National Institute of Standards and Technology (NIST) which is one of the most widely used airflow and indoor modeling program. The model was developed and calibrated to predict the …
Predicting The Severity Of Highway User Crashes On Public At-Grade Highway-Rail Crossings, Elias Wondwossen Haile
Predicting The Severity Of Highway User Crashes On Public At-Grade Highway-Rail Crossings, Elias Wondwossen Haile
Civil Engineering Theses
Highway user-rail crashes have a significant effect on highway user safety rating. However, very little attention is garnished on the subject. An understanding of the factors contributing to the levels of injury severity is an important step toward making the transportation system safer and more reliable. The main goal of this thesis is to explore the impact of various factors involved in highway user crashes on Highway-Rail at Grade Crossings (HRGCs) and provide appropriate mitigation measures. The logistic regression modeling approach (specifically ordered and unordered logit models) was applied to predict the three levels of highway user crash severity on …
Testing And Analysis Of A Post-Tensioned Coupled Wall System Monitored With Multiple Digital Image Correlation Systems, Michelle Holloman
Testing And Analysis Of A Post-Tensioned Coupled Wall System Monitored With Multiple Digital Image Correlation Systems, Michelle Holloman
Civil Engineering Theses
This thesis discusses the design and experimental evaluation of a novel seismic resistant reinforced concrete (RC) coupled shear wall system. In this system, the widely-used unbonded post-tensioned floor slab construction method is adapted to couple (i.e., link) two RC wall piers, providing significant performance and construction benefits over conventional RC coupling beams in high seismic regions. Previous experiments of post-tensioned coupled wall structures are limited to floor-level coupling beam subassemblies. The current study extends the available research to multi-story structures by construction and testing of a 15% scale eight story prototype specimen. This test is monitored by four digital image …
