Their pivotal role extends beyond mere load-bearing, encompassing critical functions in fortifying the overall strength and stability of a structure over its entire lifespan. This paper delves into a comprehensive analysis of the stress-strain state exhibited by reinforced concrete stiffening diaphragms, with a particular focus on their augmentation through the incorporation of cross-reinforcement. The primary objective is to elevate the structural performance of these diaphragms, thereby enhancing their capacity to withstand loads and proficiently distribute forces. Utilizing advanced computational techniques, this research endeavors to scrutinize and quantify the influence of cross-reinforcement on the mechanical behavior of stiffening diaphragms. By employing numerical simulations and analytical models, the study aims to elucidate the intricate interplay between the added cross-reinforcement and the diaphragms' ability to resist lateral forces. The findings from this investigation are anticipated to contribute valuable insights into optimizing the design and construction of reinforced concrete stiffening diaphragms, offering potential enhancements to the overall structural resilience of buildings. © 2024 The Authors.
