“…To find a better scaling method to reproduce the post‐cracking behavior of reinforced concrete tunnel linings, Antoniou et al 8 design a 1/30 tunnel model for analysis. Li et al 9 scale a steel‐concrete hybrid structure with buckling restrained braces at 1/10 scale, and study its seismic performance by shaking table tests. Most of these shaking table tests are targeted at simple structures such as concrete structures or steel structures, which require material similarity.…”

The shaking table testing method on small sized models is one of the most effective approaches to study the overall seismic performance of various structures. Effective design of the scale model based on a rational scaling method can ensure the reliability of the test results. In this paper, the scaling methods are summarized into three levels: material similarity, component similarity, and structure similarity. A scaling method for steel‐reinforced concrete composite structures is proposed based on the component similarity, and experiments are conducted to verify the proposed method. The results show the flexural bearing capacity error between the model columns and prototype columns is within 20%, and both their force‐displacement curves and failure modes are consistent, which demonstrates the effectiveness of the scaling method. A 1/25 scale model of a steel‐reinforced concrete composite structure is designed based on the proposed method and tested on a shaking table to evaluate the seismic performance of its prototype. This research aims to provide a reference for the scaling method for shaking table tests.

“…Y. Li et al [32] studied the failure evolution law of the reinforced anchor system under pullout load based on digital image correlation (DIC); in the anchor system, the pulling force is gradually transferred from the loading end to the free end along the steel bar. Moreover, the failure mode and the ultimate bearing capacity of the anchor system are related to the thickness of the anchor agent.…”
