Problems solved by technology

In recent years, the research on the axial compression test of the stiffened plate mainly simulates the boundary conditions at the loading end. However, in the actual structure, the non-loaded side of the stiffened plate is also supported by the adjacent structure and is not completely free.

Abstract

The invention provides a peripheral reinforcing stiffened plate axial pressure test mechanism, which comprises an upper cover plate (1), a loading structure (2), an upper end clamp (3), a lower end clamp (4), a left vertical rail (6), a right vertical rail (7) and a bottom base (8), wherein the lower ends of the lower end clamp (4), the left vertical rail (6) and the right vertical rail (7) are fixed on the bottom base (8); a stiffened plate test piece (5) is clamped between the left vertical rail (6) and the right vertical rail (7); the upper end of the stiffened plate test piece and the upper end clamp (3) are fastened through a fastening screw bolt; the lower end of the stiffened plate test piece and the lower end clamp (4) are fastened through a fastening screw bolt; the upper side of the upper end clamp (3) is connected with the loading structure (2); through the loading structure (2), the load of loading equipment is loaded on the stiffened plate test piece; the upper ends of the left vertical rail (6) and the right vertical rail (7) are connected with the upper cover plate (1). The test mechanism has the advantages that stability and repeated utilization are realized; the experiment goal is realized; meanwhile, the reasonable authenticity of experimental data can also be ensured.

Description

technical field [0001] The invention relates to a pressure test device, in particular to an axial pressure test device for a stiffened plate. Background technique [0002] As offshore oil and gas development moves from shallow water to deep water, offshore platforms that adapt to deeper working water depths, greater operating loads, harsher sea conditions, and higher operating efficiency have gradually become the main equipment for offshore oil and gas development. Structural safety is the basic premise to ensure the normal operation of offshore platforms under severe sea conditions and complex loads. According to the structural arrangement of the stiffened plate frame in the platform, applying axial compressive force to the stiffened plate can reasonably simulate the force state of the platform deck in the mid-arch or sag state. Therefore, it is necessary to carry out axial compression and ultimate strength tests of stiffened plates. In recent years, the research on the a...
