Residual stress measurements were performed using the X-ray diffraction technique.
WebIn order to equally distribute the load, a steel plate was put under the point load, as shown in Fig. (9). The static cyclic loading was achieved by increasing the load from zero KN up to 10 KN gradually with a constant rate of loading during the test, then freeing the load cell back to zero and repeating this cycle from zero KN up to 20 KN and ... WebFeb 20, 2024 · In this paper, five new joints of special-shaped double-web steel-reinforced concrete (SDSRC) columns connected with steel beams are designed. The load-displacement curves, joint yield states and damage forms of the beam ends of the five joints under monotonic loading with the same axial pressure ratio are investigated. Additionally, …
