RISProbability of Failure of High-Rise Buildings Equipped with Magnetorheological Dampers by Considering Uncertainty in Stationary and Nonstationary Earthquakes
Publisher: ASCE
Abstract: In this study, the reliability analysis of magnetorheological (MR) dampers in semiactive control of structural responses under uncertainty in seismic excitation is investigated. Uncertainties in the input earthquake exerted ...
Load-Settlement Mechanism of Shallow Foundations Rested on Saturated Sand with Upward Seepage
Publisher: American Society of Civil Engineers
Abstract: In this study, the ultimate bearing capacity and settlement of square and strip foundations in the presence of upward seepage were assessed using physical modeling. The experiments were conducted in two series with different ...
Finite-Element Simulation for Contribution of Matric Suction and Friction Angle to Stress Distribution during Pulling-Out Process
Publisher: American Society of Civil Engineers
Abstract: In slope engineering, soils are ordinarily in an unsaturated state. Today the application of unsaturated soil mechanics theory to slope stability analysis has become an essential point in geotechnical engineering research. ...
One-Dimensional Fully Developed Turbulent Flow through Coarse Porous Medium
Publisher: American Society of Civil Engineers
Abstract: A fully developed turbulent regime is considered as a specific case of non-Darcy flow, and an analytical approach has been developed to determine normal depth, water surface profile, and seepage discharge of the flow through ...
