RISInterfacial Wave Propagation at Spring Contact of Functionally Graded Fiber-Reinforced and Isotropic Elastic Semi-Infinite Media
Publisher: American Society of Civil Engineers
Abstract: An analytical approach has been presented in this research article to investigate the propagation properties of Stoneley waves at an imperfect interface between two elastic semi-infinite media with distinct properties. A ...
Effects of Soil–Structure Interaction on Dynamic Response of Framed Machine Foundation Resting on Raft and Piles
Publisher: ASCE
Abstract: Framed-foundations supporting rotary machines are either supported on a raft foundation or on a pile foundation, depending on the type of soil conditions, loadings, and other functioning requirements. Influence of ...
MDOF Modeling and Blast Dynamic Behavior of Curtain Wall with Variable Damping Approach
Publisher: ASCE
Abstract: In the present paper, a semi-active damping control approach is proposed for the resilient design of façades subjected to extreme loads in the form of blast excitation. A 4 degrees of freedom (4DOF) model is developed ...
Response of Base-Isolated Building with Secondary System under Earthquakes and Pulse-Type Ground Motions
Publisher: American Society of Civil Engineers
Abstract: Important secondary structures such as pipes may experience damage and become cracked during earthquakes. This not only may cause the piping to lose its functionality, but also may lead to secondary hazard such as fire if ...
Semiempirical Equations to Evaluate Maximum Deflection in RC Beam and Column under Fire
Publisher: American Society of Civil Engineers
Abstract: Many design regulations around the globe rely on member deflection as a governing criterion for resistance assessment in fire. The deflection evaluation in fire is generally achieved by conducting expensive experiments or ...
Robust Optimum Design for Hybrid Vibration Control of Structures under Multihazard Scenarios of Earthquakes and Winds
Publisher: American Society of Civil Engineers
Abstract: Vibration control of structures under multiple hazards poses severe problems due to the inherent variability in the features of the different hazards. A robust optimum design of a hybrid vibration controller (HVC) comprising ...
Nonlinear Buckling Analysis of Slender Piles with Geometric Imperfections
Publisher: American Society of Civil Engineers
Abstract: The buckling response of straight and initially bent, i.e., geometrically imperfect, end-bearing piles in soil subjected to axial load has been examined in the current study through FEM, considering geometric and material ...
Parametric Sensitivity Analysis and Uncertainty Quantification for Cast Iron–Lined Tunnels Embedded in Soil and Rock under Internal Blast Loading
Publisher: American Society of Civil Engineers
Behavior of Cement-Stabilized Fiber-Reinforced Fly Ash-Soil Mixtures
Publisher: American Society of Civil Engineers
Abstract: An experimental program was undertaken to study the individual and combined effects of randomly oriented fiber inclusions and cement stabilization on the geotechnical characteristics of fly ash-soil mixtures. An Indian fly ...
Correlation Analysis of Laboratory Compaction of Fly Ashes
Publisher: American Society of Civil Engineers
Abstract: Fly ash, a waste from thermal power stations, has been used in many countries to build highway embankments, fills, landfill liners, and covers. The maximum dry density (MDD) and optimum moisture content (OMC) of fly ash ...
