| Abstract | Industrial construction in Thailand faces significant challenges in achieving economical structural designs, particularly in selecting warehouse building systems that minimize material use. This thesis presents a comparative analysis of steel consumption between Conventional Steel Building (CSB) and Pre-Engineered Building (PEB) to identify the most efficient system in terms of material usage under varying design parameters. The research specifically investigates clear-span and multi-span warehouse structures, with building width ranging from 20 to 120 meters, and considers different bay spacings (6 to 10 meters) and building heights (6 to 8 meters).Structural analysis was conducted on 72 models developed using SAP2000 software, in compliance with AISC 360-10, AISC Steel Design Guide Series 25 and ASCE/SEI 7-16 standards. The applied loads followed DPT 1311-50, appropriate for buildings located in Chonburi, Thailand. The CSB systems featured roof trusses constructed from steel tubes and columns from standard H-sections, whereas PEB designs incorporated tapered built up steel sections optimized according to bending moments. The analysis systematically explored the influence of building width, bay spacing, and building height, and how their interactions impact steel consumption.The most significant achievements of this study include the creation of a comprehensive dataset on steel usage across different configurations and the demonstration that PEB systems consistently require less steel than CSB systems. In clear-span structures, the greatest absolute steel savings occurred at a 20-meter span, while in multi-span structures, it was achieved at a 90-meter span. These findings highlight the efficiency of tapered sections in PEB and emphasize the importance of considering parameter interactions in structural design to achieve material-efficient solutions for industrial warehouse construction. |
