RISExponentially Accurate Rayleigh–Ritz Method for Fractional Variational Problems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A high accurate Rayleigh–Ritz method is developed for solving fractional variational problems (FVPs). The Jacobi polyfractonomials proposed by Zayernouri and Karniadakis (2013, “Fractional Sturm–Liouville EigenProblems: ...
Residual Flexural Stiffness Calculation of T-RC Beams Considering the Effect of Fire
Publisher: ASCE
Abstract: T-shaped reinforced concrete (T-RC) beams are widely used in high-rise buildings due to their advantages of reduced concrete usage, low sectional stress, and decreased weight of the structure. However, the calculation ...
Dynamic Characterization and Design of Scotch Yoke Inerter with Adjustable Inertance for Seismic Isolation
Publisher: American Society of Civil Engineers
Abstract: The scotch yoke inerter (SYI) is a new geometrically nonlinear vibration isolator with a smaller maximum transmissibility than linear inerter systems. The influence of internal friction and the damping effect on the response ...
Modified Analytical Solutions for Purely Elastic Stress and Approximation of the Plastic Zone in Deep-Buried Circular Roadways
Publisher: American Society of Civil Engineers
Abstract: Traditional deep-buried tunnel excavation theories often overlook the self-weight of surrounding rock within the calculation zone, leading to increased design errors and potential safety risks. This study proposes an ...
