Constitutive Theory for Sand Based on the Concept of Critical Fabric Surface
(ASCE, 2020)A novel theoretical framework for the interpretation and modeling of the critical-state behavior of granular soils is proposed in this paper. The theory is built upon the hypothesis that the fabric state of granular ... -
Theoretical Analysis of Human–Structure Interaction on Steel-Concrete Composite Floors
(ASCE, 2020)An accurate determination on the acceleration response of a long-span and lightweight steel-concrete composite floor is essential for assessing the floor’s human-induced vibration serviceability, in which the interaction ... -
Modeling the Rocking and Sliding of Free-Standing Objects Using Rigid Body Dynamics
(ASCE, 2020)A rigid body dynamics algorithm is presented in this paper to simulate the interaction between two rigid bodies, a free-standing rigid object, and a pedestal that has infinite mass, in the presence of static and kinetic ... -
Novel Hidden Pounding Tuned Mass Damper for Vibration Control of a Cantilevered Traffic Signal Structure
(ASCE, 2020)Traffic signal structures are very susceptible to wind-induced vibration because of their slenderness and low damping. In the wind, the vertical vibration is usually dominant, which affects driving safety and structural ... -
Analytical CPP in Rotated Energy-Mapped Stress Space: A Finite-Element Implementation in Mathematica Software
(ASCE, 2020)This study describes step-by-step analytical closest-point projection (CPP) implicit return mapping solutions for von Mises, Drucker-Prager, and Hyperbolic Drucker-Prager yield surfaces in rotated energy-mapped stress space ... -
A New Approach for Interval Dynamic Analysis of Train-Bridge System Based on Bayesian Optimization
(ASCE, 2020)A train-bridge system (TBS) is inevitably subjected to parameter uncertainty, which leads to variability in its dynamic responses. In practice, it is difficult to characterize parameter uncertainty using precise probability ... -
Mohr Envelope Elastoplasticity
(ASCE, 2020)An often-used tool for describing the strength of geotechnical materials is the Mohr strength envelope, which has been used for more than 100 years. For simple problems, analytical bearing capacity solutions can be ... -
