Reinforced Concrete Design-1

 

Follow ACI Code (American Concrete Institute)

 

Last two digits of Registraion Number: 95

 

A simply supported beam having span length of 24′ and cross-section of 15" × 21"
is subjected to an ultimate load of ?? k/ft. Taking ?c = 3??? and ?y = 60???, 
 
a) Calculate the amount of reinforcement required for a given beam section to fail 
under balanced condition.

b) Determine the magnitude of strain developed in the tension steel at the ultimate 
stage if the magnitude of ?? = (?/10) k/ft. 

 

Where ? = Last two digits of Registration Number
