Summary This standard specifies the bridge and viaduct dynamic test and test results of the assessment method. The test methods in ISO 14963 are supplemented from the following aspects: - the purpose of dynamic testing; - data analysis and system identification techniques; - modeling of bridges; - evaluation of measurement data. The dynamic tests involved in this standard can not replace static tests. This standard provides guidance on the evaluation of the tests carried out throughout the life cycle of the bridge. The life cycle of the bridge is: - the stage of construction and acceptance; - the acceptance stage; - the specific period of the life of the bridge; - the stage of decommissioning. This standard applies to road bridges, railway bridges, pedestrian bridges, viaducts and other areas where certification can be applied during construction and use. This standard is used in certain special structures (eg,

Foreword

This standard is drafted in accordance with the rules given in GB/T 1.1-2009. This standard uses the translation method equivalent to ISO 18649..2004 (E) "mechanical vibration bridge dynamic test and test results of the evaluation estimate". And the normative reference in this standard international documents are consistent with the relationship between China's documents are as follows. GB/T 2298-2010 Mechanical vibration, shock and condition monitoring vocabulary (ISO 2041..2009, IDT) GB/T 29715-2013 Guide for dynamic testing and testing of mechanical vibration and impact bridges and viaducts (ISO 14963..2003, MOD) --- GB/T 19875-2005 Vibration of mechanical vibration and impact fixing structure in terms of vibration measurement and evaluation Quality management (ISO 14964..2000, IDT) This standard is proposed by the National Committee for the Standardization of Mechanical Vibration, Shock and Condition Monitoring (SAC/TC53).

1 Scope

This standard specifies the bridge and viaduct dynamic test and test results of the assessment method. From the following aspects to ISO 14963 The test method was supplemented by. The purpose of dynamic testing; --- data analysis and system identification technology; --- bridge modeling; Measurement of measurement data. Note 1. This standard can be used to determine all the dynamic characteristics of the measured vibration mode, ie, frequency, stiffness, mode, damping, and their motion amplitude Variable nonlinearity. The dynamic characteristics of these structures can be compared with the design model or as a basis for condition monitoring and system identification. The dynamic tests involved in this standard can not replace static tests. This standard provides guidance on the evaluation of the tests carried out throughout the life cycle of the bridge. The life cycle of the bridge is. --- pre-construction and acceptance stage; --- acceptance stage; - the specific period of the bridge life; --- is about to retire. This standard applies to road bridges, railway bridges, pedestrian bridges, viaducts and other applications that can be used during construction and use. area. This standard should be used for certain special structures (such as suspension bridge or cable-stayed bridge), should be designed for specific characteristics of the project. Note 2. In this standard, the terms "bridge" and "viaduct" are collectively referred to as "bridges". The term "viaduct" is used only to distinguish between the two.
