GB/T 13441.2-2008Mechanical vibration and shock -- Evaluation of human exposure to whole-body vibration -- Part 2: Vibration in buildings (1Hz to 80Hz) (English PDF)

Foreword

GB/T 13441 "Mechanical vibration and shock of human exposure to whole-body vibration evaluation" is divided into four parts.

--- Part 1. General requirements;

--- Part 2. Vibration in buildings (1Hz ~ 80Hz);

--- Part 4. Evaluation Guide vibration and rotational motion on the fixed rail transportation system in the passenger and crew comfort impacts;

--- Part 5. Impact Evaluation Methods include multiple vibration.

This section GB/T 13441 Part 2.

This part identical with ISO 2631-2:2003 "Mechanical vibration and impact evaluation of human exposure to whole body vibration - Part 2. Building Vibration inside buildings (1Hz ~ 80Hz) "(in English).

For ease of use, this section made the following editorial changes.

--- With "this Part" instead of "ISO 2631 in this section";

--- With a decimal point as a decimal symbol instead of ",". ",";

--- To ISO 2631-2:2003 references other international standards, have been adopted as the equivalent of a standard, instead of using our standard correspondence International standards, while others direct reference to international standards.

Introduction

Structure of human exposure to vibration in buildings, occupants can perceive and affect them in many ways. More important it is to live Comfort and quality of life of those who will be lowered.

For vibration on human comfort in buildings and annoyance evaluation of the impact of the priority use of vibration total weight. By giving the building the suitability of a location indication to indicate characteristics of people in the building location or place, with the value of the appropriate frequency weighting obtained.

This section is intended to encourage the adoption of a unified data collection method for building human vibration response.

1 Scope

GB/T his section deals with the comfort of the occupants T 13441 and worries associated buildings exposed to the human body vibration and shock, Regulation Set the measurement and evaluation methods, including measurement direction and measurement position determination. Defined in the applicable frequency range of 1Hz ~ 80Hz frequency Meter weights Wm, in this frequency range without a clear position within the building occupants.

Note 1. If the occupants a clear position, can be applied GB/T 13441.1 given frequency weighting value Wm.

Although the building is usually for a pilot study it is very effective, but at the design stage of the building into the existing building or impossible Under the circumstances, the concept contained in this section shall be equally applicable to the building. In these cases, you must use some method of building vibration ring it should be forecast.

Structural damage to the building situation may exist, this section does not provide guidance, see relevant content GB/T 14124. In addition, this section not for human health and safety evaluation of the influence.

This section does not allow vibration predetermined value.

Note 2. Before you gather more information related to this section, it is not yet given allowable vibration guide values.

Frequency weighting given value Wm mathematical definition in Appendix A, is given in Appendix B to complain about building vibration data mining Set guidelines.
