Load Limiters on Temporary Shoring Structures: Tests on a Full-Scale Building Structure under Construction
Publication: Journal of Structural Engineering
Volume 147, Issue 3
Abstract
Temporary shoring structures are used in the construction of reinforced concrete buildings to transmit the loads of newly poured slabs onto the lower floors. The main problems involved in the use of shores/props are: (1) the possibility of having higher loads than those initially foreseen, and (2) the structural efficiency and cost of the system, which is normally oversized due to being designed to bear the maximum load of the most demanding building operation. This paper describes a test carried out on a full-scale one-story building to analyze the behavior of load limiters (LLs) installed on shores under actual construction loading conditions. The theoretical approach and development of this new LL concept were described in previous papers. Because these LLs still had not been tested in actual buildings, this paper covers the existing need for a test in the form of a “proof of concept.” It also includes computer simulations and recommendations for the use of LLs.
