RISDynamic Deflections of a Stiff Footbridge Using 100-Hz GNSS and Accelerometer Data
Publisher: American Society of Civil Engineers
Abstract: The authors investigated the possibility of expanding the application of global navigation satellite systems (GNSS) into the monitoring of stiff civil-engineering structures from the current limit of dominant frequencies ...
Adaptive Fault-Tolerant Control Allocation of Flexible Satellite with Infinite-Dimensional Model
Publisher: ASCE
Abstract: This paper proposes a fault-tolerant control allocation (FTCA) scheme for a flexible satellite. A novel control strategy is implemented, which fulfills the satellite mission and also decreases vibrations, saturation time ...
Comparing the Buckling Strength of Spherical Shells With Dimpled Versus Bumpy Defects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We investigate the effect of defect geometry in dictating the sensitivity of the critical buckling conditions of spherical shells under external pressure loading. Specifically, we perform a comparative study between shells ...
Defect–Defect Interactions in the Buckling of Imperfect Spherical Shells
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We perform numerical experiments using the finite element method (FEM) to investigate the effect of defect–defect interactions on the pressure-induced buckling of thin, elastic, spherical shells containing two dimpled ...
Nanoindentation Measurements of Biomechanical Properties in Mature and Newly Formed Bone Tissue Surrounding an Implant
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The characterization of the biomechanical properties of newly formed bone tissue around implants is important to understand the osseointegration process. The objective of this study is to investigate ...
Micro-Brillouin Scattering Measurements in Mature and Newly Formed Bone Tissue Surrounding an Implant
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The evolution of implant stability in bone tissue remains difficult to assess because remodeling phenomena at the bone-implant interface are still poorly understood. The characterization of the ...
High-Fidelity Finite Element Modeling of Wood-Sheathed Cold-Formed Steel Shear Walls
Publisher: ASCE
Abstract: Cold-formed steel (CFS) framed construction has been widely adopted and used toward a modern, lightweight, and cost-efficient engineering practice across the United States. The primary objective of this work is to numerically ...
Soil–Structure Interaction Effects in Offshore Wind Support Structures Under Seismic Loading
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: This paper explores the performance of a 10 MW offshore wind turbine (OWT) supported either on a large diameter monopile or a 4-legged jacket emphasizing on the nonlinear response of its belowseabed foundation. The seabed ...
Steel Sheet Sheathed Cold-Formed Steel Framed In-line Wall Systems. I: Impact of Structural Detailing
Publisher: ASCE
Abstract: The North American construction industry has seen substantial growth in the use of cold-formed steel (CFS) framing for midrise buildings in recent years. In seismic zones, CFS-framed buildings utilize shear walls to provide ...
Steel Sheet Sheathed Cold-Formed Steel Framed In-line Wall Systems. II: Impact of Nonstructural Detailing
Publisher: ASCE
Abstract: Although cold-formed steel (CFS) framing systems have the potential to support the need for resilient housing, the use of CFS has been restricted due to gaps in understanding its structural behavior and by the limited ...
