Abstract

More reinforced concrete supertall and megatall high-rise structures are being built due to the
growing global demand for high-rise buildings, recent advancements in concrete technology, and
improvements in construction techniques. When using concrete in these structures, additional
care must be taken. Evaluating Super High-Rise Concrete Structures using various criteria is a
multi-criteria decision-making (MCDM) challenge. We propose an MCDM method with a set of
criteria and alternatives. The Root Assessment Method (RAM) is applied in this study to rank the
alternatives. The RAM method is integrated with plithogenic sets to handle uncertain
information. Plithogenic operators are used to combine the plithogenic numbers into a single
matrix. Seven criteria and nine alternatives are evaluated in this study. The results indicate that
the Structural Strength and Stability criterion has the highest weight, while the Non-Structural
Component Performance criterion has the lowest weight. Sensitivity analysis was conducted with
different criteria weights to observe variations in the rankings of alternatives. The results
demonstrate that the rankings of alternatives remain stable under varying weights.
