Physically Driven Exact Dimension Reduction of a Class of Nonlinear Multidimensional Systems Subjected to Additive White Noise
Publisher: ASCE
Abstract: Stochastic response analysis of nonlinear high-dimensional systems subjected to random excitations is a challenging issue in various engineering fields. The newly developed globally-evolution–based generalized probability ...
Copula-Based Quantification of Probabilistic Dependence Configurations of Material Parameters in Damage Constitutive Modeling of Concrete
Publisher: ASCE
Abstract: The constitutive model of concrete is the key basis for nonlinear analysis of concrete structures under disastrous dynamic actions, e.g., earthquakes. The material parameters of the constitutive model of concrete are ...
Experimental Study on the Spatial Variability of Concrete by the Core Test and Rebound Hammer Test
Publisher: ASCE
Abstract: For the nonlinear analyses of concrete structures, the complete compressive stress-strain curve of concrete is the key basis. Spatial variability is one of the significant characteristics of the mechanical properties of ...
Shaking Table Test of Seismic Isolated Structures with Sliding Hydromagnetic Bearings
Publisher: ASCE
Abstract: The sliding hydromagnetic bearing is a low-friction isolator proposed in recent years. Its novelty lies in adaptive energy dissipation and alterable deflection constraint, which has been demonstrated by previous studies ...
Stochastic Response Analysis of a Spar-Type FOWT Subjected to Extreme Waves by a Novel Filter Wave Model and the DR-PDEE
Publisher: ASCE
Abstract: Extreme waves pose one of the major threats to marine structures. Furthermore, their non-stationary nature makes proper stochastic analysis of their responses a challenging problem. To address this issue, this paper proposes ...
Application of X-Ray Micro-CT for Quantifying Degree of Hydration of Slag-Blended Cement Paste
Publisher: ASCE
Abstract: Quantifying the degree of hydration of mineral additives in a blended system has been a challenge in the concrete research community. This study attempted to calculate the degree of hydration of both clinker and ground ...
Experimental Study of Sliding Hydromagnetic Isolators for Seismic Protection
Publisher: American Society of Civil Engineers
Abstract: Sliding isolation, as one of the modalities of base isolation, has demonstrated its value in seismic hazard mitigation. Conventional sliding isolation systems, however, may exhibit unacceptable large sliding displacements ...
Numerical Investigation of the Temperature Field of a New Convection-Intensifying Composite Embankment in Permafrost Regions
Publisher: American Society of Civil Engineers
Abstract: One of the main problems of wide expressway construction in permafrost regions involves protection of the thermal stability of roadbed. Although ventilating ducts and crushed-rock layers have been successfully used in ...
