520			_aThe increasing use of concrete and steel in the construction industry raises environmental concerns, driving researchers to explore sustainable alternatives like bamboo. Recognized for its strength and flexibility, bamboo faces challenges in joinery techniques for structural applications. This study aimed to evaluate and compare the performance of various clamping techniques—Swivel Clamp, Right-Angle Clamp, and Double-Bolted Clamp with rubber—as joint connections for Kawayan Tinik (Bambusa blumeana) scaffolding. The samples were treated with a borax-boric acid solution were tested for physical properties (specific gravity and moisture content) and mechanical properties (compression parallel to grain) following PNS ISO 22157:2020. Clamps were standardized to 2-inch steel and 1.5-inch double-bolted sizes, with specimens measuring 250 mm and 500 mm in length and diameters between 50 mm and 60 mm. Connection tests, including Slipping Force, Failure Force, and Indentation, adhered to BS EN 74-1 guidelines, with each configuration replicated three times for reliability. Results showed an average moisture content of 12.21%, within the standard air-dry range (12±3%), and a density ranging from 666.576 to 725.682 kg/mm3. The average compressive strength of 58.71 N/mm2 indicated that the borax-boric acid treatment enhanced the bamboo's properties. Among the tested connections, the Right-Angle Clamp for 56–60 mm specimens performed best, with an average displacement of 8.333 mm, a slipping force of 4363.870 N, a failure force of 8768.19 N, and the shallowest indentation of 0.220 mm under a constant 1.5 kN force. Additionally, this configuration satisfied strength design loads for steel scaffolding analyzed in STAAD.Pro.
