Abstract

The safety and efficiency of beam formwork are critical concerns in reinforced concrete construction, as failures can lead to severe consequences. While advanced Finite Element Method (FEM) software is available, a foundational understanding based on the mechanics of materials remains essential for verification and practical design. This paper details a systematic methodology for the design and verification of beam formwork systems, treating components as discrete structural elements. The analysis covers the side-panels and soffit (bottom) sheathing, their supporting members (studs, stringers), and the primary shoring system. A case study for a 350 mm x 700 mm beam is presented, where all components are subjected to checks for bending stress and deflection under the action of fresh concrete and construction loads. The results validate the proposed configuration: 25 mm thick film-coated plywood sheathing supported by 50 x 50 mm timber studs at 0.315 m (sides) and 50 x 50 mm timber stringers at 0.39 m (soffit), with the load ultimately transferred to adjustable steel props via 100 x 100 mm timber bearers. All calculated stresses and deflections were well within the allowable limits of the materials. The maximum load on a single steel prop was found to be 13.5 kN, which is safely below its 20 kN capacity. This work demonstrates that a principles-based mechanical analysis provides a reliable and transparent framework for ensuring the structural adequacy and safety of beam formwork systems.
