This paper will specifically describe phosphor thermometry, a robust technology that provides accurate and reliable temperature sensing, ideal for demanding applications. I would think no portion of the slab beyond 30' from the element you are looking at (the column in this case) has an influence on the load, unless you start to consider slab continuity. These slabs offer high fire ratings, reduced sound transmission, as well as reduced vibrations between living areas. Slabs consisted of two-way bonded post-tensioned concrete with reinforced concrete beams. Please let us know here why this post is inappropriate. These are two to four story wood frame multi-family buildings on an elevated concrete slab, with parking directly below the elevated slab. 31/jul/2014 - Ryan Miller encontrou este Pin. KTGY has a long history in this typology and has designed podium buildings from coast-to-coast. Perhaps there has been some confusion in formulas that include the number 4 where that number reflects the number of floors rather than the number of bays? Close this window and log in. See more ideas about architecture, facade, facade design. Live load reductions for any structural element should be made on the basis of tributary area, not so called "influence area". agencies are often required to make design choices that are expensive and possibly conservative, e.g., requiring the plate to be positioned such that it bears on the bottom of the concrete podium. Already a member? Do you not agree that it suggests that the influence area for our case would be 4 x 60 x 60? Design Considerations for Renewing Podium Waterproofing THE L ANDSC APED PODIUM .
