Evaluation of mix ingredients on the performance of rubber-modified asphalt mixtures

Creator:: Takallou, Hossein B.
Abstract:: Rubber-modified asphalt pavements have been used in Sweden and the United States since the 1970's. In these applications ground recycled tire particles (0.25 inch minus) are added to a gap-graded aggregate and then mixed with hot asphalt cement. The benefits of adding rubber to the mix include increased skid resistance...

Experimental behavior of wide-flange beams with web holes

Creator:: Horning, Richard Alan
Abstract:: Two built-up wide-flange beams with several large holes in each beam were tested to failure. Strains were measured by strain gages at various levels, located at the ends and center of typical holes, and deflections were measured optically at two points on each beam. Lateral bracing was provided to prevent...

Wood materials and shearwalls of older light-frame residential structures

Creator:: Carroll, Cameron T.
Abstract:: Light-frame construction practices and materials have changed greatly over the past 100 years. Contemporary research has focused on modern construction; thus, we know a great deal about the behavior of modern lightframe buildings under lateral forces. However, there are many light-frame buildings that were built prior to the introduction of...

Behavior of open grid steel bridge decks under service and fatigue loads

Creator:: Fetzer, Peter C.
Abstract:: Open grid steel bridge decks have been in use for nearly a century. These open grid decks provide an economical and lightweight alternative to traditional reinforced concrete decks. As the transportation infrastructure continues to deteriorate, open grid decks can be used as a cost effective way to rehabilitate structurally deficient...

The effect of the diameter and spacing of manifold outlets on manifold flow

Creator:: Coleman, Michael Dale
Abstract:: A laboratory investigation was undertaken to evaluate the effect of lateral spacing and lateral diameter on the flow characteristics of a three dimensional blowing manifold. The model used in the experimental work was constructed of clear cast acrylic pipe, five inches in diameter. Laterals of two and four inch diameter,...

Testing and Modeling of a Cross-Laminated Timber Pier-and-Spandrel Seismic Retrofit Solution for Unreinforced Masonry Buildings

Creator:: Engleson, Renee M.
Abstract:: Cross-laminated timber (CLT) is an attractive building material because it is renewable, promotes fast installation, and possesses a high strength-to-weight ratio. The use of CLT in seismic applications has become increasingly common with the development of post-tensioned CLT rocking wall lateral force resisting systems (LFRS). The CLT pier-and-spandrel system designed,...

Pile hammer selection by driving stress analysis

Creator:: Barrero-Quiroga, Franklin
Abstract:: This paper presents an application of the wave equation to the problem of selecting a driving hammer for prestressed concrete piles. The potentially damaging effects of these types of hammers on various prestressed concrete piles were analyzed by means of parametric studies carried out on a hypothetical group of problems...

Development of a method to elucidate biodegradation pathways of chlorinated one and two carbon compounds using a gas-permeable-membrane-supported methylotrophic biofilm

Creator:: Ryan, Kelly M.
Abstract:: A gas-permeable-membrane-supported (GPMS) biofilm consisting of methylotrophic bacteria was effective in degrading chlorinated methanes, ethanes, and ethenes. The biofilm was developed on a gas-permeable fabric (Goretex, W.L.Gore & Associates, Elkton, Maryland) that divided a reactor vessel into a liquid compartment and a gas compartment. Goretex is a nylon-backed teflon mesh...

Hydrodynamic forces on a horizontal cylinder under waves and current

Creator:: Teng, Chung-chu
Abstract:: By assuming the linear superposition principle to be valid, the hydrodynamic forces on a horizontal cylinder under waves and current are examined. In this study, towing a cylinder in waves is used to simulate a cylinder under waves and current. The experimental technique is proved valid through theoretical considerations and...
