This paper presents the results of laboratory model tests performed on strip footings supported on unreinforced and geotextile-reinforced sand bed under a combination of static and repeated loads. Footing settlement due to initial static applied load was recorded, until its value become stable or failure occurred due to excessive settlement. The response under the first few cycles was found to be a significant behavioural characteristic of footings under repeated loads. The influence of various amplitudes of repeated load on foundation and different numbers of geotextile layers below the footing base on dynamic behaviour of footing were investigated. Footing settlement patterns due to repeated loading of reinforced soil is found to be comparable with increases in the numbers of geotextile layers reducing the magnitude of the final settlement and usually acting as a settlement retardant against the effects of repeated loading. The reinforcement’s efficiency in reducing the maximum footing settlement decreased as numbers of geotextile layers was increased.
