- Description
- Masonry structures contain slip joints between concrete slabs and their supporting masonry walls to accommodate differential movements due to concrete slab shrinkage or thermal effects. Traditionally slip joints consist of one or two layers of a membrane type material placed between the masonry and the concrete. These materials are usually an embossed polythene, greased steel or bitumen-coated aluminium. According to Australian Standards all structures must be designed for earthquake loading. Therefore the slip joints must satisfy two apparently conflicting requirements - slip under long-term loads and transmit short-term earthquake loads. Tests at the Universities of Newcastle and Adelaide have indicated that these types of joints exhibit substantial shear capacity under short-term loads. The performance of these joints under induced long-term strains (i.e. differential movement effects) and their potential to behave as slip joints have also been established in thermal expansion tests developed at the University of Newcastle. It was found that, of all currently used slip joint materials, embossed polythene satisfies both major structural requirements best. It is, however, desirable for the design of shear wall systems to have a wider range of materials available. The purpose of current tests is to check long term shear transfer capacity of alternative materials. Test results will be presented.
