Deflection limits for beams
Notes
- Purlins, girts and the like may exceed these limits as long as the finishing materials are not affected.
- The value for the runway girders of electric cranes depends on the actual conditions.
- For deflection vibration of beams under the dynamic effects of live load, it must be confirmed that habitability, the operability of precision equipment and productivity are not impaired.
- No numerical limit is given for the story drift of a frame. Horizontal stiffness and habitability are to be considered so that the story drift is appropriate for the horizontal loads assumed in design.
