Presented is a study on energy dissipation in dynamic inelastic systems due to material inelasticity, viscous damping, and algorithmic damping. Formulation for plastic based thermodynamics, with consideration of free energy. Computation the Rayleigh type developed discussed. Energy damping discussed as well, compared previous two, physical mechanisms. all three mechanisms illustrated relation single-element tests wave propagation problems.
This paper introduces a new and unique full-scale testbed site for structural health monitoring soil–structure system identification studies being developed in southwest China. The is 48-story skyscraper with an extended four-level basement, supported by piles, located Kunming, the capital of Yunnan Province. Located diffused zone collision Indian Eurasian tectonic plates, one most active seismic areas mainland final sensor deployment will consist 43 triaxial accelerometers (129 channels)...
Research was conducted to investigate how the inclination angle of diagonal tension field action varies in steel plate shear walls (SPSWs) and determine what optimum constant best matches demands obtained from finite-element (FE) analysis. An FE model first calibrated against experimental results that surveyed angles across web an idealized SPSW as a function drift showed significant differences at different locations plate. Then, four real SPSWs with varying aspect ratios numbers stories...
Abstract One dimensional wave propagation is studied in a cantilever conical structure deforming shear. The has rectangular cross‐section both dimensions of which decrease linearly along the polar axis (hence, doubly tapered). equation motion derived and solved terms spherical Bessel functions, can be expressed exactly as finite algebraic expressions powers sine cosine functions coordinate. transfer‐matrix for truncated pyramid element then generalized to chain elements. model used represent...
This paper employs an indirect boundary element formulation for 3D soil-structure interaction analysis in layered transversely isotropic (TI) elastic half-space under incident qP, qSV, and SH waves. Transformation matrix dynamic Green's function are employed to compute impedance coefficients, foundation displacement is computed by superposition of two cases (with without mass upper structure). Upper structure solved from equilibrium equation. An embedded with a single-point simulated study...
This article proposed a computational workflow for city-scale building damage estimation based on broadband physics-based ground motion simulation. The dynamic stiffness matrix method in frequency-wavenumber domain is employed simulation of finite fault along with site response correction using equivalent-linear analysis approach. With simulated motion, seismic buildings, multi-degree freedom model, nonlinear time history analysis, and evaluated trilinear backbone curve story’s force-drift...
ABSTRACT By employing the frequency‐wavenumber (FK) method to simulate propagation of seismic wavefield in crustal layer, using spectral element (SEM) near‐surface soil, and multi‐degree‐of‐freedom (MDOF) model response building clusters city, this paper establishes FK‐SE‐MDOF approach (a two‐step method) for urban earthquake disaster analysis fault‐to‐city based on concept domain reduction. The can simultaneously consider factors such as source parameters, paths, local site effects,...
Fast and accurate structural dynamics analysis is important for design damage assessment. Structural leveraging machine learning techniques has become a popular research focus in recent years. Although the basic neural network provides an alternative approach analysis, lack of physics law inside limits model accuracy fidelity. In this paper, new family energy-conservation introduced, which respects physical laws. The explored from fundamental single-degree-of-freedom system to complicated...
