RISAdaptive Actuator Failure and Structural Damage Compensation of NASA Generic Transport Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper studies design and evaluation of a multivariable model reference adaptive control (MRAC) scheme for aircraft systems under simultaneous actuator failures and structural damage. A key design condition–system ...
Load-Carrying Mechanism to Resist Progressive Collapse of RC Buildings
Publisher: American Society of Civil Engineers
Abstract: The slew of high profile engineering calamities in the past decade has demonstrated the disastrous consequence of progressive collapse. However, the low probability of such events actually occurring means it is uneconomical ...
Dynamic Characteristics Analysis and Finite Element Simulation of Steel–BFPC Machine Tool Joint Surface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The dynamic performance of the steel–Basalt fiber polymer concrete (BFPC) machine tool joint surface (referred to as the joint surface) has a significant impact on the overall BFPC machine tool performance; however, its ...
Peak Shear Strength of Flanged Reinforced Concrete Squat Walls
Publisher: ASCE
Abstract: Flanged RC squat walls, defined by a shear span ratio less than two, are widely used in conventional buildings and nuclear facilities. However, due to the mechanical defects and insufficient parameters included, equations ...
An Average Flow Model Considering Non-Newtonian Characteristics With Application to Grease Behavior
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the application scope of the average flow model is extended to grease lubrication considering the non-Newtonian characteristics. First, flow factor expressions applicable to both Newtonian fluids and ...
Recovery of Long-Term Missing Wind Velocity Data for Structural Health Monitoring Based on Deep Learning and Meteorological Databases
Publisher: American Society of Civil Engineers
Abstract: Wind environment monitoring is of vital importance for structural health monitoring (SHM). However, wind velocity records in SHM systems sometimes suffer from data loss owing to monitoring equipment faults, transmission ...
Multifactor Coupling Wear Behaviors of Pipeline Inspection Gauge Cups: Experimental Tests and Simulation Analyses
Publisher: American Society of Civil Engineers
Abstract: In long-distance inspection operations of oil and gas pipelines, the severe wear of the pipeline inspection gauge (PIG) cups will cause derivation of the mandrel from the pipe axis, which is detrimental to the detection ...
Validation Tests for Discrete Element Codes Using Single-Contact Systems
Publisher: American Society of Civil Engineers
Abstract: In recent years, the discrete element method (DEM) has become widely used to solve a number of geological and geophysical problems. The basic idea of this method is to consider rock-soil bodies, in their discontinuous ...
Interlayer Attraction Force in Concentric Carbon Nanotubes
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: The interlayer attraction force between concentric carbon nanotubes (CNTs) plays an important role in CNT-based nanodevices. However, the precise measurement of the interlayer attraction force remains to date a challenge. ...
Reconstruction of Extreme Wind Pressures on Cladding of a Skyscraper during Super Typhoon Mangkhut
Publisher: ASCE
Abstract: This paper proposes a novel strategy based on field measurement, wind tunnel tests, and artificial neural network (ANN) for reconstructing the wind pressures on cladding of high-rise buildings and applies it to reconstruct ...
