| dc.description.abstract | The purpose for this study was to determine the compression capacity of spacers used in the construction industry by means of experimental work, and to study load distribution within the structural of spacer by means of computational analysis. Plastic chair and wheel spacer samples were obtained from a local manufacturer of plastic spacers. Samples were tested to obtain a load displacement curve using the Universal Testing Machine (UTM). Comparison between wheel spacer and chair spacer was made. The maximum compressive load for spacers with various cover depths were tested for chair spacer. The material of the plastic spacers obtained from the manufacture had mix proportions of polypropylene (PP) and recyclable material. Computational analysis was carried out using finite element analysis software LUSAS. A finite element analysis using 3D elements was carried out to study the load distribution. Experimental results show that the maximum capacity and displacement of plastic chair spacer is higher than that of plastic wheel spacer. Current most used and available plastic wheel spacer of cover 35 mm can support an average maximum loading of 0.4537 kN. The weakest link in a plastic wheel spacer is its outer legs. Current most used and available plastic chair spacer of cover 50 mm, 40 mm and 30 mm, can support an average maximum loading of 1.185 kN, 1.148 kN, 1.850 kN respectively. Plastic chair spacers could take up to four times the maximum compressive load capacity compared to plastic wheel chair spacer for the same cover. Results of computational analysis on a chair spacer show that the trend of behaviour could be simulated satisfactorily. However, the compression capacity showed significant difference in magnitude due to unavailability of stress strain data of the actual material used for the spacer. Both laboratory test observations and computational analysis shows that the center column of the chair spacer plays a significant role in the load distribution which leads to its loss in cover as a result of compression displacement. | |
