Homogeneous versus Heterogeneous Response of a Flexible Pavement Structure: Strain and Domain Analyses
(American Society of Civil Engineers, 2019)This paper presents a computational model of a flexible pavement structure in finite elements (FE). The model is used to evaluate the response of a control (homogeneous) pavement structure, in contrast with equivalent ... -
Stresses Induced by a Moving Load in a Composite Structure with an Incompressible Poroviscoelastic Layer
(American Society of Civil Engineers, 2019)An investigation concerned with the dynamic response of a composite structure to a moving load on its uppermost rough surface has been carried out analytically. The composite structure is comprised of an incompressible ... -
Starred Polyhedral Shell Reinforced with Internal Pockets Considering an Internal Vacuum
(American Society of Civil Engineers, 2019)The concept of vacuum lighter-than-air vehicles is a generalization of the idea behind floating vehicles, which enclose a volume of gas that is lighter than air. In particular, the enclosed volume is completely evacuated. ... -
Water Column Oscillation in Partially Immersed Vertical Tubes
(American Society of Civil Engineers, 2019)Theoretical and laboratory studies were presented for the water column oscillation in a vertical tube partially immersed in a reservoir. Three types of oscillations were studied, with the top of the tube being fully open ... -
Micromechanical Modeling of Effective Orthotropic Elastic and Viscoelastic Properties of Parallel Strand Lumber Using the Morphological Approach
(American Society of Civil Engineers, 2019)Strand-based wood and bamboo composites are a class of structural materials which are increasingly being used in the construction industry. These bio-based composites consist of orthotropic wood or bamboo strands bonded ... -
Numerical Study of Containment of Spilled Medium-Viscosity Oil in Wave–Current Flow
(American Society of Civil Engineers, 2019)Offshore oil spills can greatly harm marine ecological environments. The containment boom is a simple and effective tool that can effectively prevent the spread of oil spills, reduce the oil-spreading region, and work with ... -
Fast Convolution Integration–Based Nonstationary Response Analysis of Linear and Nonlinear Structures with Nonproportional Damping
(American Society of Civil Engineers, 2019)The frequency domain approach (FDA) based on the power spectral description of input and output has been widely applied in the random vibration analysis of structures because of its high efficiency and distinct relationship ... -
Multiple Damage Identification in Beams from Full-Field Digital Photogrammetry
(American Society of Civil Engineers, 2019)This paper addresses the identification problem of multiple open cracks in beams based on damage-induced variations in the static deflection of the beam. A two-step non-model-based damage localization and quantification ... -
Hysteretic Model of Single-Bolted Angle Connections for Lattice Steel Towers
(American Society of Civil Engineers, 2019)Single-bolted angle joints are widely used on secondary bracings of lattice steel towers due to their low cost and ease of construction. It has been observed that the hysteretic behavior of these joints has a significant ... -
Simulating the Fracture of Notched Mortar Beams through Extended Finite-Element Method and Peridynamics
(American Society of Civil Engineers, 2019)This paper simulates fracture in notched mortar beams under three-point bending using an extended finite-element method (XFEM) and peridynamics. A three-phase microstructure (i.e., cement paste, aggregates, and ... -
Laboratory Study of Porosity Effect on Drag Induced by Circular Vegetative Patch
(American Society of Civil Engineers, 2019)Laboratory experiments were conducted to directly measure the drag force induced by vegetation patches under unidirectional flow conditions. The drag force was measured with a highly responsive load cell for six patch ... -
Determination of High-Strain-Rate Stress–Strain Response of Granite for Blast Analysis of Tunnels
