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...

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...

Ports '89
This is a collection of the technical papers presented at the triennial Ports '89 Conference held in Boston, Massachusetts in May 1989. Authors, although predominantly from...

Design and Performance of Diversion Gates at Peace Canyon Dam
During construction of Peace Canyon Dam, river diversion was accomplished using a combination of cofferdams and temporary diversion conduits through the partially completed dam. Inlet...

Challenging Site Conditions Lead to Unusual and Innovative Powerhouse Design Features
Pacific Gas & Electric Company's recently completed Newcastle Powerhouse is located on the shore of Folsom Lake near Auburn, California. The $26 million facility uses...

Uplift under Concrete Dams on Rock
While the possible existence of uplift pressures within dams and foundations is no longer questioned, there is still considerable controversy over the magnitude and distribution of uplift...

Uplift Pressures in Existing Concrete Dams
This paper is a brief summary of a report of the same title prepared for the Electric Power Research Institute (EPRI) as part of its program to study ways to economically improve dam safety....

Uplift Pressure below Gravity Dams on Rock
The magnitude of the uplift force at the base of a concrete gravity dam founded on rock is strongly dependent on the properties of the discontinuities within the rock mass. This paper...

Effect of Seepage in Cracks in Older Gravity Dams
One of the many problems encountered by dam designers is that of estimating uplift pressures in cracks within older concrete dams. As part of ongoing research, we are investigating this...

Lopez-Angostura Power Tunnel
The Lopez-Angostura Project is located on the Yaque del Norte River in the Dominican Republic near the City of Santiago. A 24 m high dam, a 3.6 km long power tunnel, a pit powerhouse with...
