Seismic rehabilitation of a reinforced concrete flat-slab structure
(Texas A&M University, 1999)
The effectiveness of seismic rehabilitation techniques used to eliminate punching shear failures was assessed for flat-slab structural systems. This type of retrofit was evaluated for a four-story reinforced concrete (RC) ...
Relationships between access and operating speed on suburban arterials
(Texas A&M University, 1999)
Driver behavior is affected by many roadway factors. This project investigated which geometric, roadside, and traffic control device variables have an effect on driver behavior on major suburban arterials. In particular, ...
The effect of bioremediation on microbial populations in an oil-contaminated coastal wetland
(Texas A&M University, 1999)
A series of controlled, crude oil applications was carried out in a Texas coastal wetland near the Houston Ship Channel to determine the effectiveness of bioremediation in these sensitive areas. The first application, ...
Variability of hot mix asphalt produced with reclaimed asphalt pavement
(Texas A&M University, 1999)
Pavement recycling operations have been used in the United States from the early 1900s to date. These recycling operations have been used for a variety of reasons including solid waste disposal problems, reduction of initial ...
2-dimensional numerical simulations for the wave-wake-body interactions around circular cylinders in motion near seabed
(Texas A&M University, 1999)
The 2-dimensional, viscous and incompressible flow past a circular cylinder is investigated by solving the Navier-stokes equation. solved using CFD (Computational Fluid These equations are numerically Dynamics) methods on ...
Simulation of the T6 bridge rail system using LS-DYNA3D
(Texas A&M University, 1999)
Full-scale crash testing currently the primary means of evaluating trustworthiness of roadside safety structures, such as bridge rails. However, explicit finite element analysis is rapidly becoming a feasible alternative ...
Fatigue analysis of stringer to floor beam connections in through plate girder and through truss railroad bridges
(Texas A&M University, 1999)
The objective of this thesis is to determine fatigue stresses in the stringer to floor beam connections of through plate girder (TPG) and through truss (TT) bridges in order to predict failure. Field observations by the ...
Dielectric characterization of unstabilized aggregate base materials
(Texas A&M University, 1999)
Because changes in moisture content can significantly alter the structural and strength properties of granular base materials, moisture susceptibility has a major impact on the field performance of these materials in highway ...
Development of an actuated traffic control process utilizing real-time estimated volume feedbback
(Texas A&M University, 1999)
Actuated traffic controllers are intended to determine traffic conditions, in real-time by means of vehicle detection, and respond accordingly in order to maintain the highest reasonable level of efficiency under varying ...
Assessment of durability performance of "Early-Opening-to-Traffic" Portland Cement Concrete pavement and patches
(Texas A&M University, 1999)
This study relates the assessment of durability to ''early-opening-to-traffic'' (EOT) portland cement concrete (PCC). Several factors were identified relative to the performance of EOT PCC. Each of these factors was ...
