Nonlinear Mixed‐Discrete Structural Optimization
Publisher: American Society of Civil Engineers
Abstract: This paper presents a solution code for mixed‐discrete variable optimization. An optimization algorithm comprising two different techniques, discrete steepest descent and rotating coordinate directions, originally proposed ...
State-Space Formulation for Structural Analysis with Coupled Degradation-Plasticity and Geometric Nonlinearity
Publisher: ASCE
Abstract: A nonlinear beam finite-element model is developed to account for distributed plasticity, complex degradation phenomena, axial–moment–shear interactions, and geometric nonlinearity. The formulation is derived based on ...
Hysteretic Beam Finite-Element Model Including Multiaxial Yield/Capacity Surface Evolution with Degradations
Publisher: ASCE
Abstract: A multiaxial degrading hysteretic model is developed, enabling consistent multiaxial yield/capacity surface evolution with degradations, and is appropriately incorporated in a finite-element framework using hysteretic ...
Scaled Spherical Simplex Filter and State-Space Damage-Plasticity Finite-Element Model for Computationally Efficient System Identification
Publisher: ASCE
Abstract: This work presents an efficient online system identification approach by integrating a reduced sigma points–based filter with a high-fidelity mechanics-based state-space hysteretic finite-element modeling framework. The ...
