Lift axles in ready mix trucking
(2020-04-20)
Lift axles on single-unit commercial vehicles, referred to as Specialized Hauling Vehicles (SHVs) are being used today by various industries, allowing for heavier truck loads and compliance with state / federal laws. Certain ...
Rapid and cost-effective approach to evaluate the effectiveness of wastewater and treatment byproduct solidification
(2020-05-15)
Wastewater and treatment byproducts from fossil fuel extraction (produced waters from oil and gas extraction) and combustion (flue gas desulfurization brines from coal power generation facilities) contain metals that can ...
Sources of variability in small-scale soil-geosynthetic interaction testing
(2020-08-13)
Lateral restraint is the primary mechanism associated with geosynthetic-stabilized road bases. Under traffic loading, the unbound aggregates tend to displace laterally unless they are restrained by the subgrade or by ...
Understanding traffic disruptions caused by communication network failures through survey and simulation
(2020-05-15)
Smartphone navigation applications providing real-time traffic information have become increasingly popular among drivers. Research showed that drivers' cognitive abilities for spatial navigation would deteriorate with ...
Durability and weatherproofing of building envelope materials
(2020-08-14)
The proper maintenance and long-term durability of the building envelope are two of the most important factors in achieving adequate serviceability of a building. However, products and components are typically tested using ...
A new approach to measuring pozzolanicity of Supplementary Cementitious Materials using existing ASTM standards
(2020-05-08)
Supplementary cementitious materials (SCMs) improve the long-term strength and durability of concrete systems through the pozzolanic and/or hydraulic reactions that form additional calcium silicate hydrate (C-S-H) phases. ...
Experimental investigation of bottom mat reinforcement details in drilled-shaft footings
(2020-05-14)
An experimental investigation on the structural behavior of drilled-shaft footings (pile caps) with different reinforcement details is presented. Four large-scale drilled-shaft footing specimens were tested subjected to a ...
Integrated approach for pipe failure prediction and condition scoring in water infrastructure systems
(2020-08-17)
With an increasingly aging water infrastructure, decision makers are directing their attention to better ways to model and predict asset failure. Failure modeling is a discipline that addresses complex deterioration processes ...
Application of commercial FEM program Abaqus to investigate delamination behavior of post-tensioned concrete curved walls
(2020-08-13)
The concrete delamination induced by prestressing forces is a potential problem of
post-tensioned concrete containments with curved geometry. To investigate the concrete
delamination mechanism, the researchers of the ...
State of practice in seismic rehabilitation of buildings and fragility analysis of RC columns retrofitted with FRP
(2020-08-13)
The first part of this thesis is a report intended to document the type of works for seismic building retrofits that are taking place in the state of California, where the legislation mandates retrofits of existing ...
