SMALL-SCALE STRUCTURAL MODELING FOR HIGH-RISE REINFORCED CONCRETE BUILDINGS
 
The main objective of this research is to establish a methodology for small scale modeling of structures in earthquake engineering research and practice. This work concentrates on a multi-storey reinforced concrete structure (prototype) in conjunction with a scaled steel test model. The research delves into the methodology devised to construct and elucidate the process of creating a test model that accurately reflects the essential characteristics of the prototype. The prototype was transformed into an equivalent single-degree-of-freedom lumped mass system with effective stiffness and mass. Scale modeling techniques and dimensional analysis methods have been covered in the present work. The scaling laws for prototype and test model are validated by carrying out finite element (FE) analysis using ETABS. Similitude theory is employed to develop the necessary similarity conditions (scaling laws) considering geometric and dynamic similarities. Scaling laws are formulated to encompass dimensional analysis and similarity conditions, revealing a strong correlation between the characteristics of the prototype and its scaled model through analytical studies conducted using FE analysis. The analysis outcomes consistently demonstrate satisfactory performance, underscoring the confident applicability of employing finite element analysis for dynamic analysis utilizing scaled models. The investigation into scaled model methodology proves to be exceedingly advantageous for the dynamic testing of structures, presenting conveniences in terms of efficiency, cost-effectiveness, and time savings. The study highlights the benefits of applying scaled model methodology in dynamic analysis, earthquake engineering research and practice. ORCID NO: 0000-0002-3526-7384
