Damage Model for Buildings Subjected to Earthquakes
A model based on random vibration method is developed for assessing building damage to earthquakes. The damage of reinforced concrete structures is expressed as a linear combination of...
Loads Due to Human Movements
The live loads due to human actions are random functions being modeled from data obtained from tests to determine load histories for the actions of individuals and small groups of people...
Probability-Based Load Criteria for Structural Design
Load criteria for use in limit states design of structures are developed using probabilistic methods. Statistical data on load and strengths are integrated by the reliability analysis...
Seismic Probabilistic Risk Assessment for Critical Facilities
Probabilistic Risk Assessment (PRA) for seismic events is currently being performed for nuclear power plants. The background on seismic PRA is presented along with a basic description...
Bridge Inspection by Dynamic Loading Technique
This paper describes, a case study of the evaluation of the structural integrity of a New York State Thruway bridge using the dynamic loading technique. The study was undertaken in a effort...
Seismic CPT to Measure In-Situ Shear Wave Velocity
A new test, called the seismic cone penetration test (SCPT) is described. A small rugged velocity seismometer has been incorporated into an electronic cone penetrometer. The combination...
Standards for Pile Load Tests in Permafrost
A requirement exists to establish standard procedures for conducting pile load tests in permanently frozen soils. The methods outlined in the ASTM Standards for piles in thawed soils do...
Attenuating Creep of Piles in Frozen Soils
Results of several long-term creep tests of piles in frozen soils are analyzed; the primary or attenuating creep is predominant in most cases. For effective design of pile foundations...
Creep of a Strip Footing on Ice-Rich Permafrost
Creep settlement tests were performed on a strip footing founded on the surface of ice-rich aeolian silt permafrost. The tests consisted of applying four step loadings to a 10 in. (25....
Installation of Category I Caissons
Founding a proposed safety-related Category I structure of a nuclear power plant on rock socketed caissons necessitated using precision installation techniques. These techniques were chosen...
Case Histories: Evaluation of Drilled Pier Integrity by the Stress Wave Propagation Method
The Stress Wave Propagation Method (SWPM) was used to nondestructively investigate the integrity of straight-shaft drilled pier foundations at two sites in the Denver, Colorado area. Drilled...
Behavior of Drilled Piers in Layered Soils on Texas Barrier Islands
Twenty-eight full scale load tests and the results of 41 geotechnical studies were analyzed to correlate shear strength interpreted from field and laboratory test data with those derived...
Comparison of Caisson Load Tests on Chicago Hardpan
The results from two relatively recent instrumented caisson load tests from different sites on Chicago Hardpan are compared with a 'classic' large scale caisson...
Observations on Load Tests for Drilled Shafts
This paper focuses on three specific areas pertaining to load tests for drilled shafts: 1) basic considerations and load testing procedures, 2) interpretation of uplift load test information,...
Review of Repeated Axial Load Tests on Deep Foundations
A review of the literature is presented on the axial capacity of deep foundations subjected to repeated loads. Data are summarized on anchors, driven piles, and drilled shafts. In general,...
Quality Assurance/Quality Control; Case Studies?Introduction
The report emphasizes several requirements for quality management: a. The need for a knowledgeable field representative, preferably the resident engineer. This person must be familiar...
The Role of the Quality Assurance Management on a Large Commercial Project
The role of the quality assurance manager on a high rise project being built on a tight time schedule is a challenging and diversified assignment. It is made especially difficult when...
International and Educational Aspects of Watershed Management
International donor agencies involved in furnishing technical and economic assistance for increasing food and fiber production are focusing their attention towards rain-fed agricultural...
South Branch Rockaway Storm Water Management Study
The Division of Water Resources of the New Jersey Department of Environmental Protection, the Hunterdon Soil Conservation District, the United States Department of Agriculture's...
Modeling Streamflow Response from Minnesota Peatlands
A deterministic, continuous simulation model was developed to predict the effects of peatland development on streamflow. The Peatland Hydrologic Impact Model is largely physically based...
