Introduction
By measuring, interpretation and reporting structure response, dynamic testing dynamic excitation helps control structures. Experimental design should be consistent with study
And specific target structure type. Measure commonly available full-bridge (including foundation or partial elements) and frequency domain (or) the dynamic characteristics of the time domain.
This standard applies to the design of permanent and temporary bridges, viaducts engineering construction and maintenance. Dynamic tests can be implemented as follows
purpose.
--- Assess the safety of the construction of the bridge structure;
--- Verify the design after completion;
--- Assess wind and seismic analysis of the dynamic characteristics and the live load;
--- Active monitoring of bridge damage and exploration;
--- Confirm the effect of reinforcing the bridge;
--- Bridge diagnosis during emergency;
--- As a condition monitoring based diagnostic tests.
Motion detection can be used as part of the new management or conservation and restoration design process (experimental design).
Mechanical vibration and shock
Bridge and viaduct dynamic testing and testing guidelines
1 Scope
This standard provides guidance for the dynamic test and inspection of bridges and viaducts.
--- Press construction and use of the test classification;
--- Provide guidance for control and detection of components and full-bridge type structure;
--- Listed excitation and measuring equipment needed;
--- The detection method according to the corresponding signal processing, data classification and reporting is described.
This standard provides general guidelines for dynamic tests. Dynamic Characteristics of the test resulting information can be used as condition monitoring or system identification
basis. Dynamic tests described in this standard can not replace a static test.
The test shall be described in detail all of the dynamic characteristic test of each mode of vibration (ie frequency, stiffness, vibration modes and damping) and web movement as much as possible
Non-linear change in value.
This standard applies to roads and bridges, railway bridges, pedestrian bridges and viaducts (including the construction and operation phases) and other works (or other
Project type), provide assurance in their application specific structure.
This standard applies to the special structure (cable-stayed bridge or suspension), the need to carry out specific tests according to their engineering characteristics.
Note. The below this standard, the term "bridge" refers to the "bridge and viaduct."

4.1 Overview
Subject to the dynamic behavior of the bridge superstructure type, static design and construction methods, the section type, support conditions, the type of foundation and the lower junction
Large structures (piers and abutments) impact. In the dynamic test these features need to be considered, given the classification of bridges in the 4.2 to 4.4. This
Species classification norms will help prepare a measurement report.
4.2 Superstructure type
4.2.1 Superstructure material
According to the superstructure material, it can be divided into.
