Re: CMU rebar splice

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Larry,

This is correct.  However, imagine a 10 ft free-standing CMU wall in CA with 
 #5 rebars stressed to 90% of Fs=24ksi (ASD). Will you be comfortable with 
lap-splicing these rebars by 26 inches? Like as if it was in concrete?

Thanks,

Steve
