Load-Bearing Characteristics of PHC Piles Constructed by the Inner Digging Method Based on Ultimate Load Testing and Numerical Simulation

open access: yesApplied Sciences, 2023
This paper studies the load-bearing characteristics of two prestressed high-strength concrete (PHC) pipe piles constructed by the medium mid-digging and hammering methods. The ultimate load tests and numerical simulations of the pipe piles constructed by

Dynamic response analysis of a large-diameter steel tube pile group subjected to hammering loads

open access: yesYantu gongcheng xuebao, 2017
A large-diameter steel tube pile is used in a machinery factory in Shanghai to test the new produced diesel pile hammer. However, with the increase of the diesel hammer weight, it fails to meet the test requirements and a pile group is recommended to ...

Experimental Study on Vibration Characteristics of Unit-Plate Ballastless Track Systems Laid on Long-Span Bridges Using Full-Scale Test Rigs

open access: yesSensors, 2020
In this work, we present a series of hammering tests on full-scale unit-plate ballastless tracks used for long-span bridges. There is no denying that it is a new attempt to pave ballastless tracks on high-speed railway long-span bridges; the related ...

Testing Hammer and Stanton's Reengineering Success Diagnostic

open access: yesAustralasian Journal of Information Systems, 2000
Business Process Reengineering (BPR) is no longer referenced in academic literature with the regularity that it was in the heady days of the mid-nineties but it is still in use in Australian organisations. We are also changing processes radically as new software is implemented or new electronic markets are embraced and the lessons of reengineering can ...

Estimation analysis of a defect depth in a concrete based on the adjoint variable method (Numerical experiment assuming observed displacement by the hammering test)

open access: yesNihon Kikai Gakkai ronbunshu, 2018
In this study, the estimation of a defect depth in concrete is carried out based on the finite element and the adjoint variable methods. As the governing equation, the equation of motion is employed, and the finite element and Newmark’s β methods are ...
