Adapting Overlap Per Two Floors for Vertical Structural Members:Column and Shear Wall

Abstract

The main aim of this study is adapting overlap per two floors for vertical structural members for column and shear wall. Since this concept is new and not applied widely in Ethiopia, the challenges, technical solution for challenges and economic differences were assessed and drawn. This study was used qualitative and quantitative research methodologies. The amounts of reinforcement bars were determined. In depth interviews, site observation, theoretical concepts, previous practical experience and secondary data were used. Purposive sampling technique was applied for selection of respondents and their working companies. In depth interviews were interpreted with respect to structural, architectural and cost perspectives. The results obtained from the purposively selected interviews, observations, theoretical concepts, practical experience and referring secondary materials for providing overlap per two floors on all columns and shear walls has no any effect on the architectural aspects of the column and shear wall. Because, overlapping per two floors for columns and shear wall does not affect the shape and cross section of the vertical elements and covered completely by concrete. Typically, the analysis of cost of reinforcement bars was done for G + 10 building. The total percentage of wastage of bars per two floors is reduced by 13.51% and 11.11% for 2.7m and 3.5m story height compared to per one floor respectively.
