Standardized structural design for post-disaster modular housing units under clustered environmental loads
… a multi-design standardized solution. Known environmental loading taken from building codes is analyzed over the entire United States to create a data-set that describes the distinct loading conditions of each region. Loads are clustered into grouping that suggest a single housing typology …

Saturated–Unsaturated behaviour of compacted clays
… are often compacted for geotechnical and geo-environmental construction such as hydraulic dams, road embankments, tailings containment facilities, and municipal landfills. Post construction, these earthworks are exposed to variations in seasonal weather and extreme climatic events (drought, …

Performance simulation of a composite orthopedic implant device
… hip prostheses under complex mechanical and environmental loading conditions are studied through theoretical modelling and experimental investigations. Two static strength models, namely, a cantilever beam model and an elastic foundation model, were developed using a strength of materials …

Structural damage detection using signal-based pattern recognition
… damages over their service lives due to aging, environmental loading, fatigue and excessive response. Such deterioration significantly affects the performance and safety of structure. Therefore, it is necessary to monitor the structural performance, detect and assess damages at the earliest …

Long-term response of soils subjected to repetitive geoenvironmental loads
Repetitive loading cycles originate from a variety of natural and industrial processes, affect soil properties and the long-term performance of geotechnical systems. This thesis provides unprecedented experimental data and physical analyses of repetitive environmental loading cycles on …

A Practical Carbonation Model for Service Life Design of Reinforced Concrete Structures
… binder types, as well as different locations and environmental land uses in South Africa. The validation of the design tool was done by comparing the service life prediction results to existing models, which generally showed good agreement. The developed design tool can be applied for predicting …

Early-age behavior of CRCP and its implications for long-term performance
… approach, structural responses of CRCP due to environmental and traffic loadings are computed. Damage to concrete is estimated over time, and pavement distress is predicted using empirically derived distress models. The reliability of the current CRCP design procedures depends, to a large …

The Effect of Thermophilic Anaerobic Digestion on Ceftiofur and Antibiotic Resistant Gene Concentrations in Dairy Manure
… of Ceftiofur within manure, thereby reducing the environmental loading from run-off from farms.

A Study of Durability for Elastomeric Fuel Cell Seals and an Examination of Confinement Effects in Elastomeric Joints
… different rates and temperatures after various environmental aging conditions. Additionally, tearing tests were conducted on samples tested in liquid environment. A viscoelastic and mechanical property characterization of these elastomeric seals under accelerated aging conditions could help …

Performance-Based Evaluation of Joint Sealants for Concrete Pavements
… joint sealant undergoes two types of mechanical loading simultaneously. The sealant is experiencing tension or compression as slabs contract (low temperature) or expand (high temperature), respectively. Sealants also experience shear as heavy trucks travel over the joint and deflect the ends of …

Development of a phenomenological constitutive model for fracture resistance degradation of asphalt concrete with damage growth due to repeated loading
… distress on the AC layer. Repeated traffic and environmental loading applied to the AC layer also induce degradation of the layer’s strength as microcracks grow at stress levels lower than the layer’s designed strength. In addition, this could be magnified when combined with low temperature …

Fusing Modeling and Testing to Enhance Environmental Testing Approaches
… An analytical beam was studied under applied environmental loading with grounding stiffnesses added to simulate an operational condition and the response was attempted to be matched by a free boundaries beam with a reduced number of excitation points. Due to the properties of the inverse …

Assessing the partitioning of pharmaceuticals and personal care products in secondary wastewater treatment and fate to the receiving environments
… plant and compared to predicted partition loadings and toxicity levels. The predicted partitioned loadings derived from the model were significantly different from partitioned loadings within the treatment plant. Concentrations discharged from the treatment plant were below predicted and …

Antibiotic resistance gene abundance in feces of calves fed pirlimycin-dosed whole milk
… non-saleable milk to growing calves may increase environmental loading of erm(B), which codes for resistance to highly important macrolide and lincosamide antibiotics. Additional research is needed on effects of feeding waste milk to calves on other fecal ARG and on the post-excretion and …
