CONNECTION DESIGN - DESIGN REQUIREMENTS CONNECTION DESIGN DESIGN REQUIREMENTS 29 INTRODUCTION Steel sections are manufactured and shipped to some standard lengths, as governed by rolling, transportation and handling restrictions. However, most of the steel structural members used in structures have to span great lengths and enclose large three-dimensional spaces. Hence connections are necessary to synthesize such spatial structures from one- and two-dimensional elements and also to bring about stability of structures under different loads.
strength is due to the variability of the dimensions of the elements and that of the strength of constituent material as well as errors due to simplification in analysis and design. The reasons for the high uncertainty and complexity of the connection are: Complexity of connection geometry Geometric imperfections Residual stresses and strains
