Strength Deterioration Behavior of Concrete-Filled Steel Tubular Beam-Columns
Cantilever beam-columns of steel square hollow section with or without filled-concrete were tested under constant axial load and alternately repeated horizontal load to investigate the...

Perfobond Rib Connectors for Composite Beams
In this paper, the influence of concrete strength, transverse reinforcement and concrete dowels on the capacity of perfobond rib shear connectors is examined. Perfobond rib connector is...

The Behaviour of Reinforced Concrete Beams Manufactured with Side Profile Sheets
The paper describes in qualitative terms the fundamental principles that control the behaviour of a completely new form of construction in which reinforced concrete beams are constructed...

Ovality in Pipe Rehabilitation Design
Pipes in need of structural rehabilitation often have longitudinal cracks (at the crown and elsewhere) and exhibit significant ovality (5-10%). When these pipes are lined with current...

Townsite Lateral-Stage 2 Belle Fourche Unit - Cheyenne Division Concrete: Pipe with Dumped Bedding and Embedment
In 1933, M. G. Spangler presented three bedding configurations and the concept of a bedding factor to relate the supporting strength of buried concrete pipe to the strength obtained in...

Durability of High Performance Concrete
The freeze-thaw durability and the resistance to chloride penetration of high performance concrete (HPC) developed for highway applications were investigated. This paper summarizes the...

The Proof is in the Pavement
A technique known as statistical quality assurance (SQA) lets DOTs quantify pavement quality by setting statistical guidelines for the work they will accept. SQA is a distinct departure...

Use of High Strength By-Product Gypsum Bricks in Masonry Construction
A new research aimed at producing high strength masonry bricks to be bonded with several types of joint materials other than conventional cement mortar, is introduced in this paper. This...

Use of CLSM Fly Ash Slurry for Underground Facilities
This paper presents the results of research performed in developing and using flowable fly ash slurry which falls under the classification of Controlled Low Strength Material (CLSM) as...

Airfield Pavement Structural Evaluations, Current Practice and Future Needs
The United States Air Force's pavement evaluation teams have to be able to go quickly anywhere in the world to evaluate an airfield pavement's structural capability. A combination of non-destructive...

Lime Treatment of Asphalt Mixtures in Improving Resistance to Moisture
Airport flexible pavement is susceptible to moisture damage. Lime treatment of asphalt pavement is considered to be an effective method in improving resistance to moisture. It has been...

Flyash Stabilization of Tropical Hawaiian Soils
A preliminary study of soil improvement/stabilization of several tropical Hawaiian soils with locally generated high quality flyash admixtures has shown tremendous potential as an economical...

Lime Sludge Amended Fly Ash for Utilization as an Engineering Material
Sludges generated from various water treatment operations are predominantly subject to the fate of land disposal. To prepare sludges for land disposal typically requires time consuming...

Verification of Deep Foundations by NDT Methods
Deep foundations are designed using static analysis techniques and the soil strength and structural integrity are then confirmed by static load tests. However, static tests are time consuming...

Perimeter Load Transfer in Drilled Shafts in the Eagle Ford Formation
Results of six full-scale compression loading tests at four sites in the Dallas area are considered. Compressive strengths (qc) of the rock varied...

On the Elasto-Plastic Behavior of an Unsaturated Silt
Due to technical difficulties related to the control and measurement of the suction in unsaturated soils, few experimental data on the mechanical behavior of those soils exits. The paper...

Strength Design for Reinforced-Concrete Hydraulic Structures
Strength Design for Reinforced-Concrete Hydraulic Structures, a U.S. Army Corps of Engineers engineering manual, provides guidance for designing...

The Copper-Clad Library
The design vocabulary for the new Phoenix Central Library includes saddlebags, power bellies, tensegrity and corrugated siding. The saddlebags are copper-clad, steel-framed core structures...

A Review of Design Criteria for High RCC Dams
The 1980s could be considered to be the decade during which roller-compacted concrete dams came of age. This economic method of construction is sufficiently proven that very large dams...

Designing Reinforced Rock
The reinforced rock arch design method has been used to stabilize coal mine excavations for 40 years, but so far has been applied to only a few tunnels. The use of rock reinforcement develops...
