Dynamic Test signal Analysis and Modal Parameters Identification of High-pier Long-span Rail Bridge Based on HHT Shiqiang Qina, Qianhui Pub, Zhou Shi c School of Civil Engineering, Southwest Jiaotong University, Chengdu, China, 610031 aEmail:qsqiang417@126.com, bEmail:qhpu@vip.163.com, cEmail: zshi1979@home.swjtu.edu.cn Keywords: HHT; High-Pier Long-Span; Railway Bridge; RDT; Dynamic Loading Test; Modal Parameter Abstract: Dynamic loading test is exerted on a railway continuous beam bridge with a main span of 100m and a pier of 99m high, and dynamic responses are tested under natural excitation.
For normal civil structure, amplitude A(t) and phase angle function q(t) can be written as , q(t)=wdt+f0, and introduce logarithm and differential operator,
(4) Traditional FFT method can effectively identify the frequency of the structure, but the damping ratios identified have big errors; HHT combined with RDT method can overcome the shortage of FFT, and more precisely identifying the frequencies and damping ratios of civil structures

Lean production appeared in Japan in 1950 from studies by engineers who, after a visit to Ford in the United States, have reached the conclusion that there was need for a considerate improvement in the system of mass production, and therefore would need a new production system emerging then the Lean production system, known as the Toyota production system [3].
In the third step, the search consisted in the implementation of semi-structured interviews with the engineer responsible for the work and other work employees.
