Effects of calcium-rich additives on the small-strain modulus of representative subgrade soils in Missouri
(University of Missouri--Columbia, 2012)
Calcium rich additives, such as fly ash and lime kiln dust, can improve the mechanical properties of subgrade soils, resulting in better performance and more economical pavement design. Use of calcium-rich additives in ...
Numerical modeling of static nonlinear behavior of cold-formed steel stud walls
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Cold-formed steel studs have been approved for their blast-resistance capability. Research concerns nowadays focus on how to adapt and develop the ...
Evaluation of mobility impacts of temporary ramp metering in work zones
(University of Missouri--Columbia, 2012)
Road maintenance has been growing in the United States and brings a variety of challenges to the transportation profession. Work zone congestion is one of the most important factors contributing to the delay and safety of ...
Ultrasonic stress measurement for evaluating the adequacy of gusset plates
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] A significant challenge in determining the safety margin for gusset plates is determining the level of stresses carried in the plate. Present technologies ...
Evaluation of wearing surface systems for the orthotropic steel deck of the San Mateo Hayward Bridge
(University of Missouri--Columbia, 2012)
Performance under static and fatigue loads are evaluated for two different wearing surfaces for possible use on the steel orthotropic deck of San Mateo Hayward Bridge in the bay area of California. The two wearing surface ...
Simplified analysis to predict the behavior of RC beams under collapse
(University of Missouri--Columbia, 2012)
The behavior of beams under progressive collapse plays an important role in resisting the collapse. This research addresses the complicated behavior of beams under collapse. The goal of this research is to provide an ...
Evaluation of conventional steel stud walls for blast design
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Cold-formed steel studs exhibit favorable properties of strength and ductility that could provide the toughness needed to resist blast loading. Fully ...
Predicting macroscale response of unsaturated sands from microscale analysis and simple geotechnical testing
(University of Missouri--Columbia, 2012)
A large portion, if not the majority, of conditions encountered in geotechnical engineering practice involves unsaturated soil. Practical problems include precipitation-induced slope stability failures, expansive or ...
Use of incentive/disincentive contracting to mitigate work zone traffic impacts
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Incentive/disincentive clauses (I/D) are designed to award payments to contractors if they complete work ahead of schedule and to deduct payments if ...
Evaluation of temporary ramp metering for work zone safety
(University of Missouri--Columbia, 2012)
Ramp metering has been successfully implemented in many states and studies have documented its positive mobility and safety benefits. However, there have been no studies on the use of ramp metering for work zones. This ...
Experimental evaluation of laminated glass interlayer under high strain rates
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The use of blast-resistant glazing in buildings subject to exterior hazards can greatly reduce, if not eliminate, the hazard of flying glass shards. ...
Individual and competitive adsorption of MSMA and phosphate onto iron and non-iron soil
(University of Missouri--Columbia, 2012)
Monosodium monomethylarsenate (MSMA (V)) is a common constitute in herbicides and pesticides used widely in the world, and yet its mobility and transport properties are still a relatively understudied area. Knowledge of ...
Evaluation of tensile and compressive membrane action in isolated slab column specimen
(University of Missouri--Columbia, 2012)
Older flat-plate buildings are susceptible to progressive collapse in which the failure of one slab-column connection can propagate to other connections and cause a full collapse of the building. The most common mechanism ...
