The structural assessment of rigid connections between reinforced concrete and steel members within framed buildings

Abstract

The objective of this dissertation is to investigate the use of rigid connections between reinforced concrete and steel structural members. Two-point loaded composite beams using different concrete grades will be investigated and the efficiency of the connection will be examined. The use of mechanical fasteners in the joint will also be studied. The effectiveness of moment transfer of steel reinforcement bars in the reinforced concrete member attached to the steel member will likewise be investigated. Stress-strain analysis will be used in order to predict the behaviour of the elements according to the loading and member configuration. This analytical approach will be compared with laboratory testing using a setup which could model actual construction elements. The results of this study will be used to investigate the feasibility of utilising steel-concrete rigid connections within routine construction applications.
