Sohoni, P and Jha, K N (2022) Evaluating the factors for shore selection in multi-storey building construction. International Journal of Construction Management, 22(10), pp. 1983-1992. ISSN 1562-3599
Abstract
The safety of the structure during construction depends on the load transfer mechanism from slab to shore making these components important in the horizontal formwork system. The data has been collected from India and the selection criteria for single and multi-leg shores for horizontal formwork system has been developed using the principal component analysis. This has extracted five factors in case of single-leg shores selection: (1) Shore characteristics, (2) Convenience in shore placement, (3) Cost of shore, (4) Availability of shore in required quantity, (5) Reusability of shore; and seven factors for multi-leg shores selection: (1) Tower shore characteristics, (2) Intrinsic characteristics of tower shore, (3) Availability of tower shore in required quantity, (4) Ease of shore placement, (5) Shore connection and installation equipment, (6) Cost of shore and (7) Reusability of shore. The ranking of these factors has been computed using analytical hierarchy process making it useful to the decision makers in the shore selection.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
