Hello All,
I am searching the information about deflection limits for concrete transfer beam.
The situation is that I am designing a concrete beam to support 4 stories high concrete column(load is about 100 kips ASD).
For the deflection limits, should I use L/480 with considering concrete long term deflection? Or Using L/240 is acceptable?
My colleague recommends to use L/600 with long term deflection(3 times short term deflection as estimation) as engineer judgement. But it seems too strict.
Any idea about what deflection limits should be used?
Thank you so much!
