Aug 3, 2001 · Dougantholz - It seems that deflection limits are up to the engineer who is designing, and not to exceed the limits set forth in code (l/240, l/360, l/600, etc.). Lets just say …

Oct 4, 2019 · It depends what the goal of the deflection limit is. For most deflection limits in structures, the end goal is either user comfort or preventing issues with non-structural …

Feb 1, 2013 · The proper Global deflection limit to use also has to do with what is on the roof as a roofing material - this looks like a rafter/beam situation is why I mention it. If the roof is tile, …

Oct 21, 2009 · Deflection criteria are put in place for a variety of reasons, including aesthetics, limiting cracks, mitigation of creep, and to force sections to be more resistant to "dynamic" …

Apr 16, 2012 · Are you looking at wind deflection or seismic? 0.02H is for seismic and your window wall would be damaged (but shouldn't fall off the building) in a seismic event. Most …

Feb 16, 2022 · Hi, Consider the case of a cantilever frame as seen in the attached picture. When you consider the roof beam as an individual beam with one end fixed, I consider the vertical …

Nov 8, 2022 · The out-of-plane deflection shown above (generated by the linear buckling model) does not have any physical significance, as far as I know - only useful in terms of relative …

May 5, 2021 · The load is transferred to the beams in proportion to their flexural stiffness, so the total deflection is the same as a single beam with the sum of the two beams stiffness values.

Mar 28, 2003 · I have a 2 story office building with a precast concrete panel band around the entire bldg at the second floor. Above and below is storefront. What would be a good vertical …

Jul 3, 2002 · I am trying to look for a fourier series formula that calculates the deflection and moments for plate (simply supported on two opposite edges & free on the two other edges).
