Abstract
Multi-storied buildings are indispensable in urban areas due to the high cost of land, shortage of open space and scarcity of lands. Many times these multi-storey buildings are built with regular concrete, steel and other materials where the loads are high and require heavy structures and cost may not be effective. The use of lightweight foam concrete will reduce the dead load of a structure, which then allows the structural designer to reduce the size of the columns, footings, and other load-bearing elements. Structural lightweight concrete mixtures can be designed to achieve similar strengths as normal-weight concrete. We have considered a regular eight commercial building as part of the project. Then we developed the building frame model and analyzed and designed the structural elements such as columns, beams, slab and staircases by considering vertical loads.Concrete structures are prone to earthquake due to the mass of the structures. the primary use of structural lightweight concrete (SLWC) is to reduce the dead load of a concrete structure, which allows the structural designer to reduce the size of the structural members like a beam, column, and footings which results in a reduction of earthquake forces on the structure. This study is an attempt to predict the seismic response of a eight-storied reinforced concrete frame with the use of lightweight concrete. A well-designed eightstorey example is taken for study. The structure is modelled with MIDAS application, and analysis is carried out with traditional structure and structure using lightweight concrete. The main motive of our study is to assign a lightweight concrete in a high rise structure and results are compared against structure using traditional concrete, where we can check its positive and negative effect on the stability of the structure.
