Product Introduction
The plastic ultimate load testing experimental device for MST15 beams is a core equipment in structural mechanics and steel structure design experiments, specifically designed for in-depth research on material nonlinear behavior, the formation and development process of plastic hinges, and the bearing capacity of beams in ultimate states. This device can visually display the position and rotational characteristics of plastic hinges after the beam reaches yield through precise loading, verifying the ultimate load value in theoretical calculations. Experiments not only help to master the process of solving ultimate loads based on static equilibrium method,butalsodeepentheunderstandingoftheunidirectionalrotationcharacteristics of plastic hinges and the residual deformation behavior after unloading,providing practical basis for plastic design of steel structures.
Experimental feature
1
Determination of plastic ultimate load: ①Measure the complete load displacement curve of the beam from the elastic stage, elastic-plastic stage to the complete plastic failure stage. Determine the ultimate load value when the structure loses its bearing capacity and compare it with the theoretical calculation value (based on plastic section modulus)
2
Observing the formation and development of plastic hinges: ①Intuitively demonstrate how the section develops from edge yielding to full section yielding at the maximum bending moment (such as the mid span of a simply supported beam or a fixed end support), forming a "plastic hinge" that can rotate freely. Verify the difference between plastic hinges and ordinary mechanical hinges (plastic hinges can withstand ultimate bending moments and have directional rotation)
3
Draw the P-Δ full process curve
4
Record the relationship between load and mid span deflection, and clearly divide the elastic section, elastic-plastic transition section, and plastic flow section (platform section)
