ABSTRACT
In pandemic conditions, where the COVID-19 infection is increasing exponentially, quarantine centres have become very necessary to separate and restrict the movement of people. These structures are also helpful in similar situations like disaster management, defence purposes and housing for poor people. Planning and Designing of Steel Intensive Quarantine Centre' takes on the task of designing and analysing an economical, ecological and rapid construction solution of a modular quarantine centre building. It facilitates a faster construction facility due to steel construction instead of RCC, which takes almost 70–80% more time and is not recyclable like steel. The schematic and elevation plans have been tweaked with additional architectural features to ensure ventilation, sunlight and accessible transit of patients. For economical structural design, the iterative method is incorporated to find columns with the minimum size and shape to achieve ample carpet area, i.e., star-shaped. While designing the structures, i.e., portal frame and truss roof frame are subjected to the same loading conditions. For resisting the lateral forces, different types of bracings have been incorporated in plan and elevation. The construction of a portal frame requires specialized labour to handle compound sections and connections, whereas construction of truss sections is possible by skilled labour or directly use prefabricated truss sections with the help of unskilled labour. Compound sections pose a significant challenge due to their unavailability and transportation difficulties. In contrast, the sections for trusses are readily available even in the remote market. Moreover, the construction of both structures provides rapid construction. The portal frame costs about 16% cheaper than the steel frame due to smaller sections and absence of compound sections. For validation of our work, we have used manual and automated calculation to minimize the error. The structure is expandable for future expansion by techniques such as expansion joint and satellite arrangement. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
