Shear Strength of Stud Connectors in Lightweight and Normal-Weight Concrete

摘要: STEEL-CONCRETE composite construction using normalweight concrete has been used since early in the 1920's. Substantial use of began mainly for bridge structures 1950's as a result work done by Viest. 16-18 Its primary growth building during last decade was simplified design provisions introduced into 1961 AISC Specification. The development these were based on studies reported Slutter and Driscoll. 5,11 type shear connectors changed substantially past 20 years. Bridge made extensive spiral 50's. These replaced flexible channel stud connectors. Today, headed studs are extensively both construction. first undertaken Viest, who tested full scale pushout specimens with various sizes spacings studs. 16 Later bent initiated at Lehigh University Thurlimann. 15 A series beam tests Driscoll, developed functional relationship between connector strength compressive strength. mathematical model comparable to useful capacity proposed earlier 17
