Expansion joints

This blog is created with reference data available in Google.com:

BS 6920, ASTM C 920, BS 4254, BS 6093, BS 5212, BS 5215, BS 4254, BS 5889, BS 476 (not elaborated as this is for testing for fire regarding tests), BS EN 15651, BS 3712, ACI 504R, IS 11600 and ACI 224.3R-95. Building Movement AAMA 501.4 Static, AAMA 501.6 Dynamic

There are many reasons expansion joints are required such as:
1. Structure Size / Length
2. Structure Shape or Irregularities
3. Isolation of Dissimilar Building Classifications
4. Fire Separation
5. Thermal Movement

Expansion joints may be provided at:

1. Floor-to-floor
2. Floor-to-wall
3. Wall-to-wall
4. Ceiling-to-ceiling
5. Ceiling-to-wall
6. Roof-to-roof
7. Roof-to-wall

How shall be the sealant material... As per BS EN 15651: Sealants for non-structural use in joints in buildings and pedestrian walkways, as follows: 

Part 1: Sealants for facade elements, 

Part 2: Sealants for glazing (this document), 

Part 3: Sealants for sanitary joints, 

Part 4: Sealants for pedestrian walkways, 

Part 5: Evaluation of conformity and marking. 

As per IS 6494 - expansion joints shall be not be provided in concrete swimming pools, small and medium capacity reservoir....Page No 5.

Building Movement AAMA 501.4 Static, AAMA 501.6 Dynamic:

AAMA 501.4 Static AAMA 501.6 Dynamic The seismic behaviors of façade systems are tested with three-dimensional pneumatical seismic test units in accordance to AAMA 501.4 and AAMA 501.6. In our facilities, samples as small as 1000 mm x 1000 mm and as large as 3500 mm x 4800 mm can be tested as part of the seismic test. Displacements up to 150 mm can be reached, and in dynamic tests, frequencies of 0.4 and 0.8 Hertz can be applied onto the samples. As a result, any risks of falling glass and permanent deformations are looked for, and if found, recorded to the report.

Let see the testing video:

OHSAS 18001 - Occupational Health / Safety management and System.

World-wide OHSAS 18001 is adopted for compliance and Certification by the organizations. In terms of pronunciation in running spoken parlance is spoken as osha, but when writing - it has to be written as OHSAS 18001 and spoken accordingly as OHSAS 18001.

Contact for detailed discussions and road mapping A to Z of  LEARNING on OHSAS 18001 Occupational Health Safety  Management System, and all aspects of work place safety.

Let's watch this video:

OHSAS 1800:2007 Occupational Health and Safety Management Certification is an international standard which provides a framework to identify, control and decrease the risks associated with health and safety within the worklpace. Implementing the standard will send a clear signal to your stakeholders that you view employee’s health and safety as a priority within your organisation.

An increasing number of organisations are completing OHSAS 18001 certification as employers are under increasing pressure to ensure that a rigorous health and safety policy is in place which protects employees against possible occupational risks and reduces the likelihood of accidents in the workplace. By planning ahead an organisation can also identify health and safety risks and conform to health and safety legislation.
