Abstract
Due to the escalation of the prize of construction materials, Engineers are forced to reduce the construction cost in buildings by adopting various techniques. In this project, an attempt is made to reduce the cost of the buildings in the super structures, since 70% of the cost of the building has been spent on it. A comparison of detailed estimate for steel as well as concrete has been made. To make the building economical and structurally efficient, the traditional method of load-bearing walls has been avoided by adopting steel framed structure, since the cost of a reinforced concrete-framed structures is high because of the use of cement, sand, and aggregates. Most of the loads are not fully carried by concrete, and hence, the members are not efficient. For this reason, steel super structure is considered here. The optimization on the structural components has been done by adopting techniques like bracings, lightweight floor slabs, roof slabs, and partition walls which are analyzed and designed in ETABS. Generally, the bracings are the structural component that converts lateral load into axial force. Therefore, the moment on the structure has been reduced, and hence, the stability can be improved. As steel structures are prefabricated the assemblies of these systems require less time and environmental factors can also be avoided. The structure can be completed within the stipulated time based on the requirements of the client. Hence, the construction time can be reduced in addition to reduction in the cost of the building. The economical alternative among steel and reinforced concrete building can be analyzed by doing the cost estimation of the building.
