The evaluation of Cooper ratings for in-service timber railroad bridge stringers independent of the timber specie
(Texas A&M University, 2003)
The objective of this thesis is to determine a method for assigning a rating to in-service timber railroad bridges. The standard method of rating a railroad bridge is to assign a Cooper E rating which corresponds to the ...
An experimental investigation of mine burial penetration in soft sediments
(Texas A&M University, 2003)
An experimental program was conducted to study the penetration behavior of mines in soft sediment. Model tests were conducted on sediments collected from the Gulf of Mexico seabed. The size of the model mine was approximately ...
Quantify shape, angularity and surface texture of aggregates using image analysis and study their effect on performance
(Texas A&M University, 2003)
There is a consensus among researchers that the aggregate shape properties affect performance, but a debate has risen over the suitability of these physical tests to quantify the related shape property. Most of these ...
Determination of a strength parameter for In Situ evaluation of timber railroad bridge piles subject to decay and fatigue damage accumulation
(Texas A&M University, 2003)
The objective of this thesis is to devise a method to determine the residual strength of used creosote treated timber railroad bridge piles of various dimensions that have been subjected to varying degrees of environmental ...
Evaluation of allowable stresses for high strength concrete prestressed bridge girders
(Texas A&M University, 2003)
High strength concrete (HSC) is regularly used for prestressed bridge girders in Texas and other states. The American Concrete Institute (ACI) Committee 363 (1997) defines HSC as concrete with a compressive strength ...
Accelerated quantification of critical parameters for predicting the service life and life cycle costs of chloride-laden reinforced concrete structures
(Texas A&M University, 2003)
The use of corrosion resistant steels (instead of conventional carbon steels) and/or high performance concrete can increase the overall service life and can reduce the life cycle cost (LCC) of reinforced concrete (RC) ...
A simplified formulation for moisture diffusion through partly saturated clays
(Texas A&M University, 2003)
Civil works constructed of high plasticity clays can be dramatically affected by strength loss in spite of careful compaction and moisture control. Highway embankments and retaining walls are good example of affected ...
Project scheduling using fuzzy PERT and risk management
(Texas A&M University, 2003)
Program evaluation and review techniques (PERT) is an efficient tool for large project management. In actual project control decisions, classical PERT, which is based upon beta distribution, presents a few deficiencies. ...
Numerical simulations of mine penetration in soft sediments
(Texas A&M University, 2003)
This study is concerned with developing a predictive model for depth of penetration of mines in soft sediments. The primary objective of this numerical study is to model soil resistance as a function of penetration depth ...
