Behavior and Strength of Telescopic Steel Shores

Document Type: Proceeding Paper

Part of: Serviceability and Durability of Construction Materials

Abstract:

To study the load distribution between concrete floors and shores during construction, the non-linear axial load-shortening behavior of a single post shore must be modeled properly. In this paper, a practical method to trace the axial load-shortening behavior throughout the entire range of loading up to ultimate load is proposed. Extensive studies of the behavior and strength of telescopic shores are then made using the computer model developed. Against the background of this information, a simple expression to estimate the axial stiffness of a telescopic shore is developed.
