Assalam i alikum, Can any one explain me this line please? This is from the book of Z.A SIDDIQUE PRC PART 1 ''Strength design becomes economical as compared to ASD when dead loads are relatively larger compared with live loads'' Thanks.
I have modeled a simple 6m long concrete circular column of 760mm diameter. I have applied a joint live load at the top of the column. Selecting ACI-318 as design code with frame type as sway special, I get the flexural and shear reinforcement. However, when I change the design code to AASHTO Concrete 2007 in the design preferences with zone 3 in overwrites, I get nearly same flexural reinforcement as by ACI but I observe a huge difference in shear reinforcement. It is to be noted that I have used same combination while designing by both codes. Please check the file attached and explain. G.SDB
