An Extreme-Value Model for Strength of Stiff Clays
The role of the distribution function in the safety analysis of soil structures is briefly discussed. Comparison of the two statistical distributions - normal and Weibull - reveals that...
Probabilistic Characterization of Soil Properties
Bridge Between Theory and Practice
The two objectives established for these proceedings are: (1) to summarize the principles and procedures of probabilistic characterization of soil properties in a readily understood manner...
Low Velocity Impact Tests on Reinforced Concrete Panels
The results of low velocity impact tests on reinforced concrete panels are presented. These tests were conducted to investigate the behavior of reinforced concrete flexural elements subjected...
Tension Tests of Containment Wall Isolated Liner Plates
Two tests were conducted using an approximate 2:1 ratio of hoop to meridional load. This simple load ratio is a gross approximation of the liner plate loading in a containment subjected...
Strength and Stiffness Characteristics of Steel Ladder-Type Cable Trays
Ladder-type cable trays identical with the as-built are generally tested to establish their strength and stiffness characteristics. Test data for systems in operating plants, however,...
ACI 349 Embedments: Code Provisions and Methods of Analysis
Steel embedments form the critical link between steel and concrete structures. Appendix B of ACT 349, Code Requirements for Nuclear Safety Related Concrete Structures, specifies the ultimate...
Vertical Behavior of Two 16-Year Old Drilled Shafts
Vertical load tests were performed on drilled shafts subject to lateral confining and heaving pressures from expansive soil over 16 years. Results indicated mobilized skin friction equal...
Consolidation-Strength Analysis for Soft Soils
A one-dimensional consolidation analysis including prediction of consequent shear strength increase for soft soils which exhibit large secondary compression is proposed. Consolidation...
Yield Behaviour and Consolidation. II: Strength Gain
In Part I it was shown that in situ yielding of soft foundation clays significantly affected consolidation behaviour and that yield could be defined using the effective stress path/yield...
Repairing New York's Historic Bridges
The Brooklyn and Manhattan bridges are just two of New York City's venerable structures that are undergoing rehabilitation. Current work on the Brooklyn involves enlarging...
Settlement and Stability of Ocean Disposal Mounds
This study examines the engineering behavior of dredged material disposal mounds in Long Island Sound. The study area is located about eight miles off the coast of New Haven where several...
Plunge Pool Erosion in Cohesive Soils at Two Dams in Kansas
Results of a field study of two plunge pools scoured by horizontal pipe outlets discharging on cohesive channels are analyzed. Formulas for critical tractive shear stress based on plasticity...
Structural Trends in New York City Buildings
This story is based on interviews with some leading structural engineers in New York City. It highlights the major structural trends in building design in that city. Case histories of...
Behavior of Metal Structures
This technical symposium illustrates the various aspects of transfer of information from research results to engineering practice. The papers cover historical technical background, current...
Throgs Neck Bridge: Why Did Its Deck Deteriorate?
Rapid deterioration of the concrete roadway decks of the Throgs Neck Bridge approach viaducts was found to be due to secondary tensile and fatigue stresses brought on by deflection of...
Steel Beats Concrete for Idaho Bridge
As an alternative to prestressed concrete design, the State of Idaho and the Federal Highway Administration encouraged the use of cable-stressed steel girder design for the Bonners Ferry...
Flanged Reinforced Concrete Flexural Members
Design aids in the forms of charts and tables are available for design of reinforced concrete flexural members. Many of these design aids were developed for design of rectangular cross...
Micro-Computer Program: Roof Purlin Design
A micro-computer program is explained in step-by-step manner as a shortcut for biaxial bending design with results in as little as 60 seconds. Biaxial bending requires the consideration...
Engineer's Notebook: One-step Formula for R/C Tension Steel
In the design of reinforced concrete beams, after loadings and materials are defined, the first step is to assume a beam depth. Then the required steel area and beam width are determined....
Fiber-Reinforced Concrete Proves Worth for Airport Pavements
Laboratory and field tests indicate that fiber-reinforced concrete has higher flexural and tensile strength, higher impact resistance, and improved resistance to spalling and joint deterioration...
