Vibration investigation for telecom structures with smartphone camera: case studies

期刊: JOURNAL OF CIVIL STRUCTURAL HEALTH MONITORING, 2021; 11 (3)

Telecom structures such as high guyed masts are tall and flexible, so that not only the main structure but also the components (i.e., guy cable and an......

Displacement mapping of point clouds: application of retaining structures composed of sheet piles

期刊: JOURNAL OF CIVIL STRUCTURAL HEALTH MONITORING, 2021; 11 (4)

The measurement of displacement is an important factor to evaluate the stability of a retaining structure. In this paper, a large-scale retaining stru......

Structural damage identification using modified Hilbert-Huang transform and support vector machine

期刊: JOURNAL OF CIVIL STRUCTURAL HEALTH MONITORING, 2021; 11 (4)

In the current study, a new structural damage detection algorithm is presented using the modified Hilbert-Huang transform and support vector machine. ......

Local bending deformation monitoring of bi-dimensional bridge deck based on the displacement-strain transfer matrix

期刊: JOURNAL OF CIVIL STRUCTURAL HEALTH MONITORING, 2021; 11 (3)

This paper proposes a novel displacement-strain transfer (DST) matrix method to estimate the local bending deformation of bridge deck using the measur......

Field dynamic performance testing and analysis of polyurethane track and ballasted track in a high-speed railway

期刊: JOURNAL OF CIVIL STRUCTURAL HEALTH MONITORING, 2021; 11 (4)

The dynamic performances of a polyurethane-reinforced ballast bed and an unreinforced ballast bed at an operation site were tested by using the impact......

Field measurement and validation of structural dynamic parameters of skyscrapers under super typhoon excitation

期刊: JOURNAL OF CIVIL STRUCTURAL HEALTH MONITORING, ; ()

This paper analyzes the field measurement data of wind-excited vibration responses of two skyscrapers (393 and 432 m in height) during Super Typhoon M......

Real-time monitoring system for scour around monopile foundation of offshore wind turbine

期刊: JOURNAL OF CIVIL STRUCTURAL HEALTH MONITORING, ; ()

The monopile foundation, as the main form of offshore wind turbine foundations, may be unstable owing to scouring under reciprocating currents; theref......

Field measurement of wind pressure on a large-scale spatial structure and comparison with wind tunnel test results

期刊: JOURNAL OF CIVIL STRUCTURAL HEALTH MONITORING, ; ()

Due to the features of light weight, high flexibility, and slight damping, large-scale spatial structures are very sensitive to wind load. Thus, speci......

Mapping temperature contours for a long-span steel truss arch bridge based on field monitoring data

期刊: JOURNAL OF CIVIL STRUCTURAL HEALTH MONITORING, ; ()

The temperature-induced response of long-span steel bridges can be more significant than the structural responses associated with operational loads or......

Monitoring bond strength of adhesively planted rebars in concrete using electro-mechanical impedance (EMI)

期刊: JOURNAL OF CIVIL STRUCTURAL HEALTH MONITORING, ; ()

Electro-mechanical impedance (EMI) is among the many types of gauges that can be used for structural health monitoring (SHM) of concrete structures. T......

Damage detection method for cables based on the change rate of wavelet packet total energy and a neural network

期刊: JOURNAL OF CIVIL STRUCTURAL HEALTH MONITORING, ; ()

The prestressed cables used for external strengthening and the suspender cables used for arch bridges may suffer damage resulting from the corrosion o......

Monitoring-based evaluation of dynamic characteristics of a long span suspension bridge under typhoons

期刊: JOURNAL OF CIVIL STRUCTURAL HEALTH MONITORING, 2021; 11 (2)

The Xihoumen Bridge, with a main span of 1650 m and two side spans of 578 m and 485 m, respectively, is a long-span suspension bridge spanning the Jin......

Piezoelectric-based damage-depth monitoring method for underwater energy-relief blasting technique

期刊: JOURNAL OF CIVIL STRUCTURAL HEALTH MONITORING, 2021; 11 (2)

Owing to the complex geological conditions and strict excavation shaping and damage control requirements in some underwater engineering applications, ......

Monitoring of corrosion-induced damage to bolted joints using an active sensing method with piezoceramic transducers

期刊: JOURNAL OF CIVIL STRUCTURAL HEALTH MONITORING, 2021; 11 (2)

Ensuring adequate tightening of bolted joints is necessary since they are more prone to corrosion in a harsh environment under insufficient preload. T......
