RISMatched Asymptotic Expansions of Unbalanced Adhesive Joints
Publisher: American Society of Civil Engineers
Abstract: A matched asymptotic expansion analysis is used to determine the dependence of shear stress boundary layer thickness on adhesive properties in unbalanced single-lap joints. A uniformly accurate expansion of shear stress, ...
Load–Settlement Modeling of Axially Loaded Drilled Shafts Using CPT-Based Recurrent Neural Networks
Publisher: American Society of Civil Engineers
Abstract: The design of pile foundations requires good estimation of the pile load-carrying capacity and settlement. Design for bearing capacity and design for settlement have been traditionally carried out separately. However, soil ...
On the Effectiveness of Composites for Repair of Pipelines Under Various Combined Loading Conditions: A Computational Approach Using the Cohesive Zone Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: ASTM PCC-2 standard provides a series of equations for establishing the composite repair's thickness required for bringing the capacity of dented/damaged pipes, to their original design state. However, the accuracy of the ...
Variability of Fiber Reinforcement, Peel Strength, and Internal Shear Strength in Needle-Punched GCLs
Publisher: ASCE
Abstract: The objective of this study was to evaluate variability in reinforcement fibers, peel strength, and internal shear strength of needle-punched reinforced geosynthetic clay liners (GCLs). A methodology was proposed to ...
Influence of Key Environmental Conditions on Microbially Induced Cementation for Soil Stabilization
Publisher: American Society of Civil Engineers
Abstract: Microbially induced calcite precipitation (MICP) is a sustainable biological ground improvement technique that is capable of altering and improving soil mechanical and geotechnical engineering properties. In this paper, ...
League Championship Algorithms for Optimum Design of Pin-Jointed Structures
Publisher: American Society of Civil Engineers
Abstract: In this paper, a new optimum truss design approach based on the league championship algorithm (LCA) is introduced. The LCA is a novel metaheuristic algorithm inspired by sporting competitions in sports leagues. Assuming ...
Active Vibration Control of a Flexible Beam Using a Buckling-Type End Force
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we explore the use of end forces for vibration control in structural elements. The process involves vibration measurement and observer-based estimation of modal amplitudes, which ...
Enhancing Controllability and Observability in Underactuated and Undersensed Systems Through Switching: Application to Vibration Control
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Many dynamical systems use transducers that can function both as actuators and sensors. It is possible to continuously switch the functionality of the transducer elements in such systems and ...
Minimizing Cutting Wastes of Reinforcement Steel Bars Using Genetic Algorithms and Integer Programming Models
Publisher: American Society of Civil Engineers
Abstract: Materials that are in the form of one-dimensional stocks such as steel rebars, structural steel sections, and dimensional lumber generate a major fraction of the generated construction waste. Cutting one-dimensional stocks ...
Tailoring Plate Thickness of a Helmholtz Resonator for Improved Sound Attenuation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this work, the transmission loss of a Helmholtz resonator is maximized (optimized) by allowing the resonator end plate thickness to vary for two cases: (1) a nonoptimized baseline resonator and (2) a resonator with a ...
