Performance evaluation of high-rise reinforced concrete buildings under dynamic loading considering different structural systems

Abstract

With the growing construction of towering structures owing to modernisation and growth in land use, tackling the height and stiffness concerns are now essential. Several structural systems have been developed to withstand various loading scenarios, including framed systems, shear wall systems, braced framed systems, outrigger systems, and diagrid systems. The present investigation employs E-tabs software to accomplish dynamic analyses on a G + 16 story RCC building with regard to every structural system. The variables studied were base shear values, storey shear force values, maximum displacement values, maximum storey drift values, stiffness of storey levels, and time periods. The major goal was to find the most appropriate system among those examined. This study can add to our knowledge concerning building dynamics and helps to make well-versed assessments about prospective high-rise constructions and the findings can be useful in the design of high-rise structures. After accomplishing the study, it was demonstrated that for numerous response parameters, the diagrid structural system proved to be the most successful in managing lateral forces, functioning similarly to the shear-walled model. The diagrid structural system's efficiency in optimising stability and resistance against dynamic loads demonstrates its potential for improving the safety as well as the performance of these structures. Finally, the diagrid system offers potential as a feasible high-rise building choice, providing an efficient and effective response to the issues faced by urbanization-driven vertical expansion.
