Behavior and Design of Bolted Circular Hollow Section (CHS) Moment Connections

Abstract

This chapter outlines the work done in the current research. Main points of the research are presented along with the conclusions and outcomes. Recommendations for future research are also highlighted. The primary aim of this research is to study the behaviour and design of the bolted circular CHS joints subjected to pure bending moment. The research includes a state-of-the-art literature review for the studied joint covering many aspects related to the joint behaviour and design, as presented in Chapter 2. This review confirms the need for further studies regarding the behaviour of joint under bending moments. The literature review also includes the experimental programme used in the verification of finite element analysis investigation. Two finite element models are developed using a well-known general-purpose finite element analysis (FEA) package, known as ABAQUS/CAE. The modelling techniques and assumptions are described extensively in Chapter 3. FE results are verified against the experimental programme found in literature and good correlation between results are found
