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.
