Use of Experimental Data to Develop Probable Behavior
The intent of this paper is to present results of research that studies the performance of the University of Colorado walls tested by Professor Benson Shing. These walls would be classified...
On-Site Incineration
A variety of equipment is now available for incinerating hazardous wastes in situ. Thermal treatment, compared to land disposal, offers limited liability and immediate destruction. It...
Architectural Configurations in Vina del Mar
This paper identifies the architectural characteristics of 121 reinforced concrete buildings in Vina del Mar. These characteristics are related to the damage statistics for the building...
Comparison of Slitted and Non-Slitted R. C. Shear Walls With Boundary Elements Under Horizontal Forces
This paper compares the differences of aseismic behaviours between slitted and non-slitted shear walls under horizontal forces. There are 5 specimens for slitted shear walls and another...
Seismic Strengthening of a Tall Masonry Building
The design of a strengthening system for a tall building is proposed using ductile reinforced masonry shear walls. This innovative design concept produced a system that controlled the...
Development of Inelastic Reduction Factors to Provide an Elastic Design Procedure
R factor values can only be rationally selected when they are based on in part nonlinear inelastic dynamic analyses of building system types. However, it is informative to discuss the...
The Church on Stilts
Christ Church Cathedral is an Anglican church situated in the heart of downtown Montreal. Constructed in 1859, it is a perfect example of English neogothic architecture, characterized...
Jet Grouting to Construct a Soilcrete Wall Using a Twin Stem System
An existing coal loading pier located in Norfolk, Virginia was completed in 1961 for the purpose of loading ocean going ships. It was determined that dredging adjacent to the pier would...
Sulfated Polysaccharides from Marine Invertebrates
The authors Laboratory is involved in the chemical and structural determination of sulfated polysaccharides from different sources. The main purpose of such studies is to compare these...
Structural Design, Analysis and Testing
This volume contains the papers presented in 21 sessions of the 1989 Structures Congress held in San Francisco. The papers cover a wide range of topics including types of construction...
A New Turbulence Model: The k-?-S Model
A new turbulence model, the k-?-S( turbulent kinetic energy-dissipation-Stochastic theory) model, is presented. Instead of the Boussinesq eddy viscosity concept in the k-? -E( turbulent...
The Role of Vegetation in River Bank Erosion
The purpose of this paper is to describe briefly how streambank vegetation, both roots and shoots, modify the 'skin' or surface layer and how this in turn affects...
Sediment Ramping at Mill Creek
A Corps of Engineers study completed in 1988 analyzed this ramping phenomenon Mill Creek in Southern California Using an approach which combined sedimentation research with Corps experience...
Considerations to Be Taken in the Design of Speed Increasers for Hydroturbine Service
The paper discusses the incorporation of a speed increaser specification that is primarily functional yet one that will address the cost, reliability, efficiency, and life requirements...
High-Rise Embankments
Embankments reinforced with geosynthetic materials are being built at increasing heights. Any wall over 20 ft is still generally considered high, but embankments of 40 ft with near vertical...
Transferring Construction Innovation into Practice: Lessons Learned
The paper presents several cases that illustrate the value of a systems approach in the need for aggressive and persistent exploitation despite early set-backs, and the unsatisfactory...
Building Onto History
In a single design/build/renovation project, an Oklahoma City AE firm acquired new offices, provided new life for an abandoned historic church building and spearheaded redevelopment of...
A Station With a View
The Port Authority TransHudson Corp. (PATH) is renovating and expanding Exchange Place station, the first stop in New Jersey across the Hudson River from lower Manhattan. To be completed...
Drawing up Waterproof Curtains
Curtain wall damage has recently become the number one source of building owner complaints. Until wall systems are designed with backup water collection systems and other details, leakage...
The `Down' of Top Down
The 800-space parking area for the Milwaukee Center was built in a four story deep basement of the building. In order to excavate the area without damaging two adjacent historic structures,...
