Popis: Compared to reinforced concrete, steel structures are lighter and it is about 18 times more ductile than concrete. So, for high rise buildings steel structure can be a good choice. Theoretically, a lighter building will be less vulnerable to lateral forces. As a riverine country, pile foundations are commonly used as high-rise building foundations in Bangladesh. Pile foundations are frequently required to support lateral loads and moments, particularly in seismically active areas such as Bangladesh. This paper is based on the analysis of pile foundation due to lateral loading. The analysis was carried out using both a Combined analysis method and a simple conventional analysis procedure. In combined analysis superstructure element and pile foundation was considered simultaneously which is the real practical situation and the differences in deflection between the two processes were determined later. Lateral forces were calculated using BNBC 2020 and used to examine the 2D frame structure on ETABs. Both of Combined analysis and simple conventional analysis was used to conduct the analysis procedure. It was observed that there were significant differences between them in different perspectives like deflection, axial force, bending moment was considered. According to soil stiffness for particular analysis, the top layer influences more than the lower layers. Analysis was also done for varying soil stiffnesses. So, Combined analysis should be chosen to ensure more accuracy and a safer design.
