PROJECT: STEEL BUILDING DESIGN CASE STUDY. SUBJECT: JOIST SELECTION (ECONOMICAL BAY STUDY) Investigate two framing options: Option I - joists span 30', Option II - joists span 36'. This bay framing study is done for joists (sheets 16-17), interior floor girders (sheets 18-22), and. interior fill beams (sheet 23-24). Comparison bays are priced out (sheet 25) to select economical bay framing.
This discovery of spontaneous âradioactivityâ (a term coined by Becquerelâs doctoral student, Marie Curie) eventually earned Becquerel a Nobel Prize for Physics in 1903, which he shared with Marie Curie and her husband Pierre Curie.enchmarks: Henri Becquerel discovers radioactivity on February 26, 1896. Credit: A photographic plate made by Henri Becquerel shows the effects of exposure to radioactivity. A metal Maltese cross, placed between the plate and radioactive uranium salt, left a clearly visible shadow on the plate.
The Nobel Prize in Physics 1903 was divided , one half awarded to Antoine Henri Becquerel  in recognition of the extraordinary services he has rendered by his discovery of spontaneous radioactivity  , the other half jointly to Pierre Curie and Marie Curie , nÃ©e Sklodowska  in recognition of the extraordinary services they have rendered by their ...
