Behaviour of BH Girder Composed of CIP and Precast concrete Subjected to Flexural Loading

Abstract

This paper presents the behaviour of reinforced BH girder which is made of precast, and cast in place (CIP) subjected to flexural loading (bending). The girder is made of two types of concrete materials, precast and cast in place (CIP), which has different strengths. The girder is simply supported and loading force is given at the mid span of the beam during analysis. The main objective of the analysis and modelling is to studying the combined effect of CIP, precast and the reinforcing materials. Modelling process is carried out using Rigid-Body-Spring-Network (RBSN) and Abaqus commercial software. Cracking and failure behaviour of the girder is investigated. Performance of the BH girder (precast and CIP) is estimated based on the load carrying capacity. Deflection of the composite is measured along the span of the girder. From the analysis result; the ductility, load carrying capacity and crack initiation and crack propagation behaviour of BH girder is investigated.
