Analytical description of the creep of expanded polystyrene (EPS) under long-term compressive loading
The results obtained from investigating the compressive creep behaviour of expanded polystyrene (EPS) are presented. It was found that power-law (as in EN 1606) and exponential regression equations used for describing the compressive creep curves agree equally well with experimental results, taking...

| description | The results obtained from investigating the compressive creep behaviour of expanded polystyrene (EPS) are presented. It was found that power-law (as in EN 1606) and exponential regression equations used for describing the compressive creep curves agree equally well with experimental results, taking into account the uncertainty.
It has been shown that sufficiently reliable predictions of the creep strains of EPS for lead times of 10, 25 and 50 years can be made based on an empirical exponential equation populated with the data obtained in direct experiments with a duration of 122, 152 and 304 days, respectively. |
