Dynamic-Fatigue Response of Continuous Composite Bridges
The dynamic response of continuous composite bridges and the influence of fatigue loading at resonance frequency on the structural response are investigated. It is shown that cracking...
The Eurocodes and Shrinkage in Composite Beams
The two parts of this paper relate to different aspects of design procedures for composite structures of steel and concrete. First, recent developments in the coordination of the eight...
Experimental Investigation of Composite Rigid Frames
According to the series of tests conducted by the authors on composite rigid frame models, the compressive principal stress in the steel web plate at the corner panel was considerably...
Mixed Systems: Past Practices, Recent Experience, and Future Direction
A comparison is made between composite column capacities derived from the authors procedure utilizing the ACI (America Concrete Institute) code requirements, and previously published semi-empirical...
Bond Check for Concrete-Filled Steel Tubular Columns
In order that a concrete-filled steel tubular column may display a maximum bearing capacity for sustaining the long-term vertical loads transferred from the steel beams to the steel tube...
Beam to Column Stress Transfer in Composite Structures
To clarify the mechanism of the stress transfer from the steel beam to the composite column through the beam-column joint, eight exterior beam column assemblies were tested under reversed...
Shear Strengths of Concrete-Filled Steel Box Elements
This study evaluated the ultimate strengths as well as the effect of the ultimate composite actions of concrete-filled steel composites under combined bending, shear, and axial forces....
Seismic Capacity Evaluation of SRC Buildings
The Japanese standard for seismic capacity evaluation of existing composite steel and reinforced concrete (SRC) buildings was introduced. As it developed, based on the previously established...
Seminar Summary and Research Needs
All the papers presented in the technical sessions of the seminar are summarized and, in some cases, commented upon. The needed research in composite and mixed construction is described....
Reshaping the Future of Plastic Buildings
Plastic structures have been around for 40 years, but have for the most part been showcases with little use in the mainstream of the building industry. To be used effectively, plastics...
High Strength Steel
A
New Pavement from Old Concrete
Recycling portland cement concrete has gained momentum as an alternative to resurfacing aging highway and airfield pavements. Recycling cuts down rawmaterial requirements, reduces the...
Building on Muck
The Craney Island Disposal Area at Norfolk, Va. is a 2,500 acre depository for material dredged from ports and channels in the Hampton Roads. The U.S. Army Corps of Engineers extended...
Personnel Policies for Operations Management in the Computer Age
The human factor is an essential ingredient and the key element in successful computer applications for water resources or any other field. Engineers in general, and engineering managers...
A Riverine Toxic Spill Model
In the event of a spill of toxic material reaching the main stem of the Potomac River, predictive information regarding its location and concentration would aid in the minimization of...
Fluidization of Biomas Covered Sand Particles
The expansion behavior of the fluidized bed reactor support medium is important in its design and analysis. Steady state and dynamic behavior of fluidized bed expansion were compared with...
Modular Plastic Media for Shallow Bed Trickling Filter Applications
Little specific data is available for less sophisticated trickling filter systems which employ recent plastic media designs for shallow bed filters without the added cost of subsequent...
Method Development for Evaluating Radionuclide Emissions from Incineration of Low Level Radioactive Waste
The implementation of an incineration monitoring program for low level radioactive waste is a complex task, especially in the area of obtaining environmental permits. Emissions monitoring...
Direct Filtration of Colored Water Supplies
The effects of raw water quality, chemical treatment, and filtration variables on the performance of direct filtration are examined. Cationic polyelectrolytes as sole coagulants are effective...
Optimization of Design and Operating Parameters for Single-Media, Unstratified-Bed Filters
The potentially successful use of filters containing large grain-size single media for water filtration has prompted investigation of the parameters controlling the performance of these...
