LRFD composite beam design

LRFD composite beam design


-Check design shear and flexure strength of a simply supported I section composite beam to AISC LRFD 3rd Ed. 
-Note that for "unshored" construction, total deflection is sum of deflection of the steel beam under its own load, and deflection of the composite beam under dead and live loads. For "shored" construction, total deflection is sum of deflection under dead and live loads for the composite section only. 
-Based on methods used in "Steel Structures Design and Behaviour" by: Salmon & Johnson (see pages 1010-1061) 
-Transformed Section method has been used to calculate elastic section properties 
-It is assumed that all shear will be transferred through Headed Studs and that concrete and steel sections form a fully composite section 
-Steel Material assumed to conform to ASTM A922 
-See AISC LRFD Specifications Chapter I
