Studies on the Development of Economical Drainage Systems for Multi-Storeyed Buildings

摘要

The report presents results of an analytical investigation carried out with a view to formulating rational design procedures for economical drainage systems in multi-storeyed buildings, thus obviating the limitations of semiempirical design procedures presently in vogue. Specifically the systems investigated include the 'Single Stack' (SS) and the 'Modified One-Pipe' (MOP) systems that have proven economical advantage over the conventional 'Two-Pipe' and 'One-Pipe' systems of drainage. The analytical models have been validated through experimental data collected on full-scale multi-storey testrig facilities. An excellent correlation between the negative pressures predicted by the analytical models and those recorded experimentally for both the systems brings to the fore the utility of such analytical models for design of drainage systems in multi-storeyed buildings.
