In a rigid diaphragm, the intraocular deformation equals zero; that is, the infiltration of the inside of the diaphragm is infinite and the movement of all nodes inside the class is dependent on the master joint. That is, with the displacement of the center of the diaphragm mass, the displa...
The normalized ultimate load is defined by: τu fc = P u⋅h⋅fc ; control perimeter, u = π ⋅(d + h) which, used on the experimental results, gives the following Wöhler chart: 0.035 0.030 0.025 0.020 0.015 0.010 0.005 0.000 0 Wöhler chart of dynamic tests y = 0.024x -...
The drop hammer impact device used in the test can accurately position the drop hammer at the required height and accurately control the position of the hammer body impacting the surface of the rail. The drop weight frame can move freely on the beam and can also provide different drop weight...
