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...
Design Load Combination Factors
This paper reviews alternative load combination formats for ultimate limit states in codified structural design. The need for explicit consideration of load-time variations and random...
Design Considerations for Wind Loadings
The application of reliability concepts to the treatment of wind loadings on structures has increased in the past several years. Advances have been made in assessing the various uncertainties...
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 Analysis of Horse Creek Dam, Hudson, Colorado
On April 8, 1981, six days after a Richter magnitude 4. 0 earthquake, inspectors from the Colorado State Engineer's Office discovered a small crack in outboard side of Horse...
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...
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....
Bentonitic Slurry in Constructing Drilled Piers
Bentonitic slurry is employed extensively in the construction of drilled shafts. While serious problems can occur, evidence is presented to show that the proper use of slurry will lead...
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...
Predicted and Measured Performance of a Foundation
The predicted and measured short term foundation behavior of a 28 story building in downtown San Antonio, Texas is reported. The soil is a stiff to hard clay and clay shale. The design...
Geotechnical Behavior of Underreams in Pleistocene Clay
Enlarged bases are often constructed in cylindrical drilled-and-cast-in-situ foundation elements (footings, bored piles) to increase their capacity. Enlarged bases that are cut mechanically...
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,...
Soldier Creek Dam Foundation Drainage
A possible mode of failure for Teton Dam, piping of erodible core material through unsealed foundation joints, was also concluded as being possible at Soldier Creek Dam, Utah. Evaluations...
An Application of Probability to Rock Slope Design
This paper describes the use of probability and statistics in the slope design process. An example is presented of a high rock slope in an open pit mine. This slope is a major concern...
A Combined Limit Equilibrium and Statistical Analysis of Wedges for Design of High Rock Slopes
This paper describes a unique technique developed for the statistical analysis of wedge failures which control the design of high slopes in relatively hard jointed rock masses. Using this...
Probability Applied to Slope Design?Case Histories
A major problem encountered with the choice of an appropriate value for the design probability. Initial experience, obtained during open-pit investigation, suggested that slope geometry...
