  • Abstract:
    This paper presents structural modeling and design considerations for a double-layer shoring system made of wood posts based on analytical derivation, numerical computation, and the LeMessurier formula. Simplified two-dimensional models of double-layer shoring systems are developed. The analysis shows that system critical loads do not increase with the addition of individual pinned-ended shores, i.e., leaning columns, in the system during construction. If these individual pinned-ended shores are widely used, more cases of falsework failure may occur. The effects of lengths of horizontal stringers and vertical shores, stiffnesses of stringers, and positions of strong shores are investigated in the paper. The reinforcement by addition of bracing to the shoring systems can improve the system buckling strength. The study concludes that appropriately fastening a group of pinned-ended shores with horizontal bracings, i.e., strong shores, can increase the load-carrying capacity of a double-layer shoring system.
