Development of Large-scale Bending and Torsional Test Rig Using Strong Floor Anchorage System for Structural Analysis

Abstract

Abstract The common practice among researchers is to use scaled models for validation. However, using scaled models can lead to errors due to the scaled factor. To overcome this problem, this paper presents the development of a large-scale bending and torsional test rig for structural analysis which is involves testing the actual scaled model of the structure. In this research, a portal frame powered by a hydraulic system anchored to a strong floor is developed to evaluate specimens’ sizes up to 6 m x 2 m, such as planar frame and space frame structures. The design of the strong floor and the test rig will be analyzed for three-point bending, four-point bending and torsional tests. For stress analysis, it was found that the design of the test rig is capable of carrying out three-point bending test up to 37.6 kN, four-point bending test up to 75.2 kN, and torsional testing up to 4.1 kN.
