EXPERIMENTAL STUDY ON STATIC STRENGTH OF STUD CONNECTORS IN THE CONCRETE RESTRICTED BY STEEL PLATES

Abstract

Presented in this paper are push-out test results on the ultimate strength of stud connectors buried in concrete which are restrained by flanges and a web of H shape steel members (Series-T) or by box shape steel members (Series-C). At first, four types of parameters, - (i) the degree of restraint, (ii) numbers and arrangements of studs, (iii) the strength of concrete, and (iv) existence of reinforced steel bars - are selected. The influence of these parameters on the ultimate strength is studied. At second, the estimation methods of the ultimate strength of stud connectors restrained by steel members are investigated. As a result, equations to calculate the ultimate strength of test results in Series-T, and C are proposed.
