Deformability of Reinforced Concrete Members
A large volume of test data has been evaluated to establish deformability of reinforced concrete beams, columns, and structural walls in the inelastic range. Experimentally observed deformation...
Bermed Shelters Subjected to Accidental Explosions
An investigation of the adequacy of two competing shelter designs to protect the occupants from an accidental explosion in a nearby shelter is described. Two bermed shelters, one of rectangular...
Residual Capacity of Explosively Damaged Reinforced Concrete Columns
The results of load tests on explosively damaged reinforced concrete columns are presented. The method used to correlate an ultimate strength, laminar type of reinforced concrete analysis...
Structural Resistance of Slabs for Blast Loading
Results from a series of static tests on one-way reinforced concrete slabs are summarized. The slabs were loaded with a uniform pressure and tested to large deflections. Parameters varied...
Reevaluation of Reinforced Concrete Slabs Subjected to Blast Effects
Failures in reinforced concrete shallow-buried structures subjected to the effects of severe dynamic loads are reevaluated by employing a modified Timoshenko beam formulation which includes...
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...
Dams Reborn
The need to rehabilitate dams without draining their valuable reservoirs is impacting the way the Bureau of Reclamation makes modifications. There are no two better examples of this than...
Concrete Removal Techniques with Potential for Use in Rock
This paper describes concrete removal techniques that were employed in the rehabilitation of US Army Corps of Engineers mass concrete structures and are thought to have potential for limited...
Investigation and Modeling of Soil-Structure Interface Properties
An investigation of some techniques suggested to reduce friction at the soil-structure interface, for example plastic sheet on sand, is presented, and a model proposed for characterizing...
Comparative Performance of Two Pile Types
This paper reports on the pile driving and load bearing characteristics of the two pile types driven at a plant site in Sumatra, Indonesia. Nine prestressed concrete piles were driven...
Pile Foundation Construction Practice in Stiff Clays with Dense Granular Layers
A survey was conducted recently in conjunction with a project located in the San Francisco Bay Area to ascertain the general pile driving practice in stiff overconsolidated clays interbedded...
Augered Cast-in-Place Piles
Development of the augered cast-in-place pile system from origination in the late 1940's to the present state of the art is presented, with methods of pile placement, including...
A Lateral Load Test on Seven Foot Diameter Caissons
Seven foot (2.1 m) diameter caissons (drilled shafts) were designed to support a mainline eastbound bridge and an off-ramp of Interstate Highway 70 in Glenwood Canyon, Colorado. A lateral...
Combination Drilled Shaft and Driven Pile Foundation for a High-Rise Building
A case history is presented which discusses the design and construction of a combination drilled shaft and driven pile foundation which supports a high-rise in San Francisco. Drilled piers,...
Structural Materials
This volume of Structural Materials contains papers from 12 sessions of the 7th Structures Congress held in San Francisco on May 1-5, 1989. The sessions cover a very broad range of topics...
The Area of Scour Hole Around Bridge Piers
The study is focused on what parameters determine the area of scour hole around bridge piers. An analytical study based on momentum principle has been used to reveal the variables involved...
Award for an A-Frame
The Waddell A-frame truss bridge that now stands in Parkville, Mo. was neither the longest, largest nor most all-encompassing civil engineering project of 1988. But the story behind the...
Top Projects for 1989
Transportation-related projects, most notably bridges, dominate the 1989 OCEA projects, but each of the 11 improved the quality of life of people in the community without harming the environment....
Scour Assessment at Bridges
Due to the key role that bridges play in the national transportation system, the Federal Highway Administration has developed a scour evaluation program. This program, issued in the form...
Local Scour at Bridge Abutments
Comparison of local scour depths at bridge abutments computed using different equations yields a large variation in predicted values. To consolidate the fragmented results of previous...
