Pseudo dynamic test of cantilever columns with variable cross-section

  1. Variation of collapse modes of columns with the location of change in cross-section
  2. Specimens before test [49kB]
  3. Specimens after test [53kB]
    4.
  4. Variation of collapse modes of columns with the combination of material strength
  5. Column 1 & 2 before test [47kB]
  6. Column 1 after test [51kB] [Lower cross-section remains elastic.]
