A Look at the New ACI Concrete Code
Building Code Requirements for Reinforced Concrete (ACI 318-83) is discussed in terms of three major changes: limitations on chlorides, especially in aggregates, that affect durability;...
LAX Takes Flight for the 1984 Olympics
LAX (the Los Angeles airport) had over two dozen contractors working on site to complete their $700 million improvement plan in time for the Olympics in July. They also came up with several...
The Sand Dam
Currently under construction is the 443 ft. high sand fill dam. Being erodible, pervious and liquefiable, sand would normally be considered as n unsuitable material to construct LaVueltosa...
Seismic Risk and Decision Analysis of Lifeline Systems
This paper provides general guidelines for performing lifeline seismic risk and decision analyses. Relevant input models are introduced as they support the performance of component and...
Performance of Water and Sewer Lifelines in the May 2, 1983 Coalinga, California Earthquake
Water supply and filtration systems for the City of Coalinga suffered little damage. The water transmission system suffered five breaks. The urban distribution system was disrupted, but...
Water Supply
The Foothills Project adds 125 mgd (5.5 m�/s) to the Denver area water treatment capacity, and saved approximately $1 million in energy costs in the first year of its operation. The $163...
Caisson
The Jamaica Bay Water Pollution Plant was renovated and upgraded from l973-l983 and included sinking a 116 ft. x 105 ft. caisson 50 ft. deep adjacent to city streets and buildings. The...

Pipe Impact on Concrete Slabs
A series of pipe impact on concrete slab tests have been performed at the CEA's Cadarache Laboratory using the AQUITAINE II facility. The testing program was jointly sponsored...
Design for Whipping Pipe Impact on Reinforced Concrete Panels
This paper describes determination of local and overall effects on reinforced concrete panels due to whipping pipe impact in postulated pipe break events. Local damage includes the prediction...
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...
Reliability Assessment of Indian Point Unit 3 Containment Structure Under Combined Loads
In the current design criteria, the load combinations specified for design of concrete containment structures are in the deterministic format. However, by applying the probability-based...
Sensitivity of Peak Dynamic Responses to Input Factors
Responses have been calculated for the Zion Unit 1 plant, using the SSMRP computer code SMACS, as part of the seismic probabilistic risk assessment performed by the Seismic Safety Margins...
Seismic Capacities of Masonry Walls at the Big Rock Point Nuclear Generating Plant
