sizing of a rc frame
my question is how can you derive the dimensions of a rc frame.i have my dead loads and imposed loads but i dont know which codes to use.if you know any good books plz let me know.its a frame with 18 m span .
the code to use would depend upon where your structure is located. the governing jurisdiction (city, county, etc) would identify its model code to use.
