CORE DESIGN STRATEGIES FOR PORTAL STEEL FRAMES: A STRUCTURAL ANALYSIS

Abstract

The practical implementation of portal steel frames has witnessed notable advancements through the strategic incorporation of inclined beams. This innovative addition serves a dual purpose, enhancing overall structural stability while curbing the consumption of foundational materials. The result is an effective cost-control strategy, ensuring economic feasibility during the construction process. Additionally, the introduction of lightweight steel structures within portal steel frames contributes to a substantial reduction in the overall structural weight. This not only promotes the structural system's seismic performance but also underscores its suitability for a wide range of applications, particularly in the construction of single-storey houses and industrial plants. The utilization of portal steel frames equipped with lightweight steel structures offers a cost-effective approach to single-storey house construction. This synergy between structural elements enables a practical and efficient construction process. Consequently, portal steel frames have become an integral component in the construction of industrial plants, facilitating enhanced efficiency and cost-effectiveness. However, for these structural systems to fulfill their full potential, a systematic analysis is indispensable to address the myriad challenges inherent in the design process. A continual commitment to enhancing design quality remains the cornerstone of broadening the scope of their application.
