Numerical Analysis and Parametric Study on Multiple Degrees-of-Freedom Frames

The design of multiple degrees-of-freedom frames is critical in civil engineering, as these structures are commonly used various applications such buildings, bridges, and industrial structures. In this study, a six-degrees-of-freedom beam-column element stiffness matrix was formulated by superposition beam truss elements matrices adapted to statically analyze indeterminate frame development numerical model for the achieved using finite method current study. Also, investigation effects parameters geometries, material properties, loading conditions conducted on internal forces developed Three different parametric study cases that presented with varying geometries were analyzed utilizing approach sake emphasis evaluate flexibility adequacy formula MATLAB software. analysis comprised derivation system displacements employing relationships between fixed end force vector taking attained displacements, which would be transformed local coordinates obtain member forces. computed results from further statistically compared software (SAP2000) applying variance (ANOVA). statistical showed P-value > 0.05, indicated good correlation adequate performance derived method.
