Abstract

To enhance the application of arch-shaped beams in public buildings, this article utilizes ABAQUS and engineering design software to analyze the impact of different structural measures on the stress performance of a high-rise building’s large-span cast-in-place reinforced concrete arch conversion beam.

Four structural models are constructed: a pure RC arch beam-column, an arch steel beam-column, an arch steel beam-column with internal steel support, and a rectangular steel beam-column with steel support. These models are systematically analyzed to assess stress conditions under various structural conditions.

The research reveals that the concrete arch beam exhibits a significant arch effect, resulting in a distinct force transfer path compared to conventional RC beams. This characteristic poses challenges for traditional engineering design software to accurately capture and calculate stress states.

To address this, a “hollow honeycomb” concrete construction measure is adopted at the arch foot of the framed arch beam, reducing self-weight and conserving concrete usage. Additionally, steel supports are emphasized to be placed in critical areas of the pressure arch transfer path to maximize their support function and enhance structural stress performance.
