RISWarping Effects in Transverse Bending of Thin‐Walled Beams
Publisher: American Society of Civil Engineers
Abstract: A beam theory which accounts for cross‐sectional warping caused by transverse shearing is presented. A stress resultant theory is formulated for elastic beams, and examples are provided to assess the effects of warping ...
Optimal Design of Frames to Resist Buckling under Multiple Load Cases
Publisher: American Society of Civil Engineers
Abstract: This paper suggests an optimization‐based design methodology for improving the strength and the overall stability characteristics of framed structures whose capacities are governed by limit‐load behavior. Attention is ...
Optimal Design of Planar Frames Based on Stability Criterion
Publisher: American Society of Civil Engineers
Abstract: This paper suggests an optimization‐based design methodology for improving the strength and overall stability of framed structures, the capacities of which are governed by inelastic limit‐load behavior. The optimization ...
Approximate Analysis of Post‐Limit Response of Frames
Publisher: American Society of Civil Engineers
Abstract: An approach to estimating the limit and post‐limit behavior of a framed structure from its geometrically linear response is presented. The method follows from a particular restatement of the weak form of the nonlinear ...
Damage Detection and Assessment of Structures from Static Response
Publisher: American Society of Civil Engineers
Abstract: A damage detection and assessment algorithm is developed based on a parameter estimation with an adaptive parameter grouping scheme. Damage is characterized by a reduction in a constitutive property of a parameterized ...
Analysis and Implementation of Resilient Modulus Models for Granular Solids
Publisher: American Society of Civil Engineers
Abstract: Constitutive equations based upon stress dependent moduli, like
Simple Nonlinear Model for Elastic Response of Cohesionless Granular Materials
Publisher: American Society of Civil Engineers
Abstract: A constitutive model based on hyperelasticity is proposed to capture the resilient (elastic) behavior of granular materials. Resilient behavior is a widely accepted idealization of the response of unbound granular layers ...
Structural Damage Detection and Assessment from Modal Response
Publisher: American Society of Civil Engineers
Abstract: This paper presents a global damage detection and assessment algorithm based on a parameter estimation method using a finite-element model and the measured modal response of a structure. Damage is characterized as a reduction ...
Variational Basis of Nonlinear Flexibility Methods for Structural Analysis of Frames
Publisher: American Society of Civil Engineers
Abstract: There have been a number of contributions to the literature on a class of structural analysis methods referred to as
Piecewise Linear Warping Theory for Multilayered Elastic Beams
Publisher: American Society of Civil Engineers
Abstract: Warping due to transverse shear in multilayered elastic beams is studied in this paper. The Bernoulli-Kirchhoff hypothesis that plane sections remain plane after deformations, with independent rotations, is assumed for ...
