Comparison between bs 5950 and eurocode 3 for the design of pre-engineered steel structure of a factory

Comparison between bs 5950 and eurocode 3 for the design of pre-engineered steel structure of a factory / Chuah Hoi Ching
Matlamat projek ini adalah untuk merekabentuk anggota-anggota keluli termasuk kasau dan tiang bagi struktur pra-kejuruteraan dengan menggunakan dua piawaian reka bentuk yang berbeza iaitu British Standard 5950 (BS 5950-1-1: 2000 “Code of Practice for Design – Rolled and Welded sections”) and Eurocode 3 (MS EN 1993-1-1: 2010 “General rules and rules for buildings”). Selain itu, kelebihan dan kelemahan penggunaan Eurocode 3 dalam reka bentuk keluli berbanding dengan BS 5950 juga dikaji dalam projek. Hasil projek ini menunjukkan bahawa reka bentuk menggunakan Eurocode 3 mengalami prestasi struktur yang lebih rendah dalam analisis awal tetapi lebih tinggi dalam analisis akhir berbanding dengan reka bentuk yang menggunakan BS 5950 bagi gabungan kritikal. Keupayaan struktur untuk reka bentuk Eurocode 3 termasuk keupayaan ricih, keupayaan paksi dan keupayaan momen untuk bahagian yang digunakan dalam analisis ini adalah lebih tinggi daripada reka bentuk BS 5950. Kestabilan panjang untuk haunch dalam reka bentuk Eurocode 3 lebih panjang berbanding dengan reka bentuk BS 5950. Namun, kestabilan struktur reka bentuk Eurocode 3 termasuk rintangan lengkorkan kilasan sisi dan rintangan lengkokan disebabkan oleh interaksi masa paksi dan lentur adalah lebih rendah berbanding dengan reka bentuk BS 5950. Berat keluli yang diperlukan bagi reka bentuk Eurocode 3 adalah 0.88% lebih banyak berbanding dengan reka bentuk BS 5950. Perkara ini adalah disebabkan oleh saiz keratan yang lebih besar diperlukan dalam reka bentuk Eurocode 3 bagi memenuhi semua keperluan. Secara kesimpulan, penggunaan BS 5950 dalam reka bentuk adalah lebih murah daripada reka bentuk Eurocode 3. _______________________________________________________________________________________________________ The aim of this project dissertation is to design selected pre-engineered steel structural members including rafter and column with non-typical section by using two different design standards which are British Standard 5950 (BS 5950-1-1: 2000 “Code of Practice for Design – Rolled and Welded sections”) and Eurocode 3 (MS EN 1993-1-1: 2010 “General rules and rules for buildings”. The advantages and disadvantages of design using Eurocode 3 including cost effectiveness of the design compared with BS 5950 are determined in this project dissertation. The findings show that design using Eurocode 3 experienced lower structural performance in initial analysis but higher in final analysis compared to design using BS 5950 for critical combination. The structural capacities of Eurocode 3 design including shear capacity, axial capacity and moment capacity for the section used in this analysis are higher than BS 5950 design. Although the stable length for haunch in Eurocode 3 design is longer than BS 5950 design, the structural stability of Eurocode 3 design including the resistance of lateral torsional buckling and resistance of buckling due to interaction of axial and bending moment are lower compared to BS 5950 design. Lastly, Eurocode 3 design consumes 0.88% more still weight than BS 5950 design. This is because larger section sizes are required for Eurocode 3 to fulfill all requirements. Therefore, it can be concluded that BS 5950 design is cheaper than Eurocode 3 design.
