- Deflection Limits - Structural engineering general discussion - Eng-Tips
Ignoring vibrations as a servicability check, a 35-foot long beam would have a maximum live load deflection, using this criteria, of 1 17 inches The maximum dead + half live load is 1 5 inches If then we take T Galambos's paper from 1986 (published in ASCE Journal of Structural Engineering) the probability of seeing the actual deflection is

By now a RC building is allowed to sustain a 1 250 total actual deflection under the applied total service level load with a proper calculation of the deflection, including stiffness degradation by mechanical cracking and creep (obviously checked generally in approximate ways) AS LONG what is called the active deflection doesn't surpass 1 cm or
- Allowable deflections for Residential Floor Beams - Eng-Tips
Limit 1: Live load deflection less than L 360 for L < about 8 ft, L 480 for longer spans Limit 2: Total load deflection less than L 240 for L < about 8 ft, L 360 for longer spans, but never more than 3 4" Limit 3: Beams parallel to a wall below: Total load deflection < 2D 240 max, where D is the distance from the beam to the adjacent wall
- Deflection check - Structural engineering general discussion - Eng-Tips
Calculate the deflection of the supporting beams B1A and B1B (at he location where they support B2, whichever one you're looking at they'll all be different obviously) And then by geometry you can determine how much influence the deflection of B1A and B1B have on the globabl deflection of B2
- Is the 0. 6 wind load reduction(ASD) just to check deflection? - Eng-Tips
Deflection check of MWFRS can be done utilizing the appropriate wind speed from the maps found in the commentary of the code They provide values for 10-year and 25-year events Typically deflections are calculated at 10 or 25 year return periods Multiply the deflection you calculate for MWFRS using [V(10 or25)^2 Vult^2)]
- Brick Deflection Limits 1 - Eng-Tips
Australian code has not total deflection limit but limits deflection to L 500 for articulated brickwork (joints ar 18' or less) and L 1000 if not jointed 3" at L 600 is equivalent to about 15' so similar to the aticulated brickwork span in the Australian code This agrees with haynewp's comment suggesting jointing the brickwork
- deflection limits - Student Engineer General Discussion - Eng-Tips
From International Building Code (IBC) Table 1604 3 Deflection Limits: Note i) reads " l = Length of the member between supports For cantilever members, l shall be taken as twice the length of the cantilever " Therefore for each "position condition" in the table, the allowable deflection is some fraction of length of the given member
- Roarks Circular Ring Formulas - Eng-Tips
Deflection for the uniform load can be handily calculated, and is simply a uniform growth of the ring Deflection due to the equally spaced point loads is from Load Case 7 So far, so good Load situation is shown in the attached sketch, Figure A, and predicted deflection in Figure B
