Re: Expansion Joint in Building

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Hi Edmondo,

The local building code is, of course, your primary information source.
In our practice here, you don't need to slice the foundation at the expansion joint (note however that this doesn't hold for deformation joints).
In the national codes that I've looked through (CIS, Germany, Czechia), the requirements for expansion joints vary greatly (40m to >100m) depending on what type of structure you're designing, environment conditions etc. These are to be defined by calculation.

Just wondering the requirements for expansion joints in building--in Saudi, they require a building (50m x 100m for instance) to provide expansion joints for every 50m in both horizontal dimensions. Please advice if it is needed to separate the building into two parts including the structure below the ground--grade/tie beams. I understand, that it is needed for thermal expansion. What does other do?
