Bond Stress of Embedded Steel Shapes in Concrete
This paper describes an investigation into the bond stress developed between steel shapes and reinforced concrete when the concrete is lightly stressed. A brief discussion of previous...
Recent Developments for Composite Buildings in Japan
Research work and construction practice of composite steel and reinforced concrete structural systems in Japan are reviewed, based on the data gathered by the working group of the Architectural...
Design of Framed Steel Structures with Infill Reinforced Concrete Walls
It is a well-known fact that an infill shear wall in a frame acts as a compressive diagonal strut, giving strength and inflexibility to the frame. Recently the Architectural Institute...
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...
Composite and Mixed Construction in Czechoslovakia
Various composite and mixed systems have been used in Czechoslovakia. Special attention is focused on design methods, effective construction, and material savings. Current developments...
Seismic Strengthening of Existing RC Buildings
Seismic strengthening of existing reinforced concrete (RC) frame buildings by the use of steel braces or panels was studied experimentally. A special joint between steel elements and the...
Binding and Bonding Concrete to Composite Columns
Composite interaction between concrete encasement and structural steel shapes is limited unless lateral ties and/or mechanical attachments insure such interaction until desired strength...
New Ways with Concrete
When NASA builds on the moon and in space, the structures will be concrete, say researchers at the Portland Cement Association's Construction Technology Laboratories. They...
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...
On-Site Containment of PCB-Contaminated Soils
A remedial investigation/design project, with subsequent post-closure monitoring, was conducted for upland areas containing PCBs at an industrial site in New Bedford, Massachusetts. A...
Roller Compacted Concrete
Roller compacted concrete has emerged recently as an economical material and rapid method of construction for use in gravity dams, overflow structures and heavy duty pavements. The economics...

Recent Developments
The Foothills Project has been under consideration by the Denver Board of Water Commissions for many years. It is one of the major steps in the continued efforts of the Board to provide...
Rock Masses
Modeling of Underground Openings/Probability of Slope Failure/Fracture of Intact Rock
While soil mechanics has been the dominant interest of Civil Engineers since Karl Terzaghi's recognition of the principle of effective stress, rock mechanics is becoming increasingly...
Shrimp Farm Made Feasible
Engineers on a limited budget developed a facility on the island of Oahu, Hawaii, where Mexican blue shrimp are being raised commercially. A series of U shaped sections were laid parallel...
Clay Pipe Installation?Advances in Load Factors
This report presents an evaluation of traditional load factor values for clay pipe and the development of a new bedding system which gives a higher load factor. Tests demonstrate that...
Failure of a Large Reinforced Concrete Pipeline
This paper describes the damage that occurred when a landslide overloaded an 11 ft diameter reinforced concrete pipeline. The 8 ft lengths of pipe, each of 11. 5-in. wall thickness, were...
SPIDA: An Analysis and Design System for Buried Concrete Pipe
The paper presents a description of a new computerized direct design method for buried concrete pipe named SPIDA (Soil-Pipe Interaction Design and Analysis). Also the technical basis and...
Experiences in Concrete Pipeline Construction in Ontario 158-1985
The paper discusses the title subject in terms of concrete pipe fabrication methods and plants, pipe jointing and jointing materials, and construction experiences in the Province of Ontario,...
Proportioning Reinforcement for Buried Concrete Pipe
The proportioning of reinforcement between inner and outer cages that is specified in ASTM Standard Specification C76 for concrete pipe in sewer and culvert applications is examined in...
Influence of Frost Action on the Load Exerted on Buried Pipe
When work was started on revising the Swedish code for concrete pipes at the end of the 70's, a research project was carried out to evaluate the risk of increased load due...
