Re: crack control

[Subject Prev][Subject Next][Thread Prev][Thread Next]
The issue of crack width, brings the following questions to my mind of:

(1) Do most people check crack width for only beams and one-way slabs as implied by the 
section title where crack provisions are given or is crack width checked for other 
concrete members like footings, walls, and two-way slabs also.

(2)  When checking rebar service stresses do most people use the load factors like 1.4 
and 1.7, or do they use 1.0 or do they use something else.
