Abstract

Construction of high-rise concrete buildings relies extensively on multi-level formworking; a process in which a limited number of formwork and shoring sets are cycled up the structure as construction progresses. This multi-level formworking procedure relies on supporting a freshly cast slab on a number of lower level slabs, which may or may not have attained their full strength. Currently, the multi-level formwork shoring procedure and slab construction cycle times for buildings with post-tensioned slabs are selected based on the requirements for conventionally reinforced slabs. As such, cycle times of 4 or 5 days and 3 or 4 levels of shoring are common. This paper proposes, however, that due to the inherently different behavior of post-tensioned slabs, it may be possible to shorten slab cycle times, reduce formwork and shoring materials and improve construction safety.

Impact and interest:

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
