Comparing Two Approaches for Assessing Observation Impact
Publisher: American Meteorological Society
Abstract: angland and Baker introduced an approach to assess the impact of observations on the forecasts. In that approach, a state-space aspect of the forecast is defined and a procedure is derived ultimately relating changes in ...
Wood Floor Behavior: Experimental Study
Publisher: American Society of Civil Engineers
Abstract: A series of 13 wood floors was tested under uniformly distributed load. The floors were manufactured with 12 (nominal)
Horizontal Response of Piles in Layered Soils
Publisher: American Society of Civil Engineers
Abstract: An inexpensive and realistic procedure is developed for estimating the lateral dynamic stiffness and damping of flexible piles embedded in arbitrarily layered soil deposits. Starting point is the determination of the pile ...
Reliability of Wood Structural Systems
Publisher: American Society of Civil Engineers
Abstract: A methodology for the study of reliability in wood structural systems under load is presented. The approach implements duration of load effects by means of a damage accumulation model, and combines it with a structural ...
Constitutive Modeling and Discontinuous Bifurcation Assessment in Unsaturated Soils
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work an elastoplastic constitutive theory for unsaturated soils is presented. The proposed material model is formulated in the general framework of the theory of porous media and of ...
Dynamic Response of Arbitrarily Shaped Foundations
Publisher: American Society of Civil Engineers
Abstract: The paper presents a method to compute the effective dynamic stiffnesses
Undrained Monotonic and Cyclic Triaxial Strength of Sand
Publisher: American Society of Civil Engineers
Abstract: The undrained behavior of saturated sand in monotonically loaded triaxial tests is discussed using steady state concepts. The relations among various drained and undrained strength envelopes are first examined. These ...
Effect of Soil Plasticity on Cyclic Response
Publisher: American Society of Civil Engineers
Abstract: A study on the influence of the plasticity index (PI) on the cyclic stress‐strain parameters of saturated soils needed for site‐response evaluations and seismic microzonation is presented. Ready‐to‐use charts are included, ...
Seismic Response of Shallow Foundation on Liquefiable Sand
Publisher: American Society of Civil Engineers
Abstract: Eight centrifuge model experiments were conducted to investigate the mechanism of liquefaction-induced settlement of a shallow foundation, as well as the effectiveness of sand densification by vibrocompaction under the ...
Lateral Cyclic Loading Centrifuge Tests on Square Embedded Footing
Publisher: American Society of Civil Engineers
Abstract: Cyclic lateral loading centrifuge tests were performed on a model of an embedded foundation to study its lateral response at various displacement levels up to ultimate lateral load capacity. The tests simulated a reinforced ...
