Abstract - Soil Structure Interaction is interaction between
angles [3-4]. They allow for innovative architectural designs and complex geometries, making them ideal for futuristic buildings, bridges, and large-scale projects [12]. Non-parallel systems add flexibility, both in aesthetics and functionality, to modern construction practices [5].
the structure and soil that when the structure placed at the ground due to which is developed force on the soils, and soil push the structure. The plan of the structure except the rectangular or square shape is come under the non parallel system such as plan of the structure is just like parallelogram. As we know that now a days construction is going in the vertical means high rise structure due to which the load on the structure is heavy so, to bear that load we are using the Concrete Steel Filled Tube (CFST) Column. We have studied previous research based on the SSI, CFST, Non parallel system, and we found that all author studied the individual parameter, and here compiled all parameter to studied in the single different models. The main objective of this research work to check the stability of the structure among the first model examines a non-parallel RC frame system without SSI and with RC columns, while the second model incorporates SSI effects into a similar RC column structure. The third model explores a non-parallel system without SSI but with concrete-filled steel tube (CFST) columns, and the fourth model evaluates a system integrating both SSI effects and CFST columns. The method used in this research work is Dynamic Analysis by using Time History Analysis.

1.1.1.Concrete-Filled Steel Tube (CFST) Columns Concrete-Filled Steel Tube (CFST) columns combine the strengths of two materials: steel and concrete [6]. The steel tube provides external support and confinement, while the concrete inside enhances compressive strength [7]. CFST columns are valued for their ability to handle heavy loads, their durability, and cost-effectiveness. They are widely used in high-rise buildings and bridges, where strength, efficiency, and space-saving solutions are crucial [8-9].
Key Words: Soil-Structure Interaction, Non-Parallel System, CFST Columns, software.
1. INTRODUCTION 1.1 Background Soil-Structure Interaction (SSI) is a critical aspect of structural design because it helps engineers understand how the soil and structure influence each other. When a building or bridge is placed on the ground, both the soil and the structure react to the forces between them [1]. Ignoring this interaction can lead to inaccurate predictions of performance, especially during earthquakes or heavy loading. By accounting for SSI, structures can be designed to be safer, more stable, and cost-efficient [2].
1.1.2.Challenges in Modeling SSI for Non-Parallel Systems Modeling SSI for non-parallel systems is quite challenging because of their unique geometry and load behavior. Unlike straightforward structures, non-parallel systems have complex load paths and irregular connections. Accurately simulating how the soil interacts with such designs requires advanced software, detailed soil properties, and a deeper understanding of dynamic forces. These challenges make SSI modeling for non-parallel systems a highly specialized and intricate process.
Non-parallel structural systems are becoming increasingly popular in modern construction [10-11]. Unlike traditional designs with components at right angles, these systems involve beams and columns arranged at unconventional
