  Abstract

  Using the ABAQUS finite element analysis platform, this study established numerical models of H-section steel members with trapezoidal corrugated webs and a three-story corrugated web steel frame. The dynamic characteristics of the frame structure were investigated via modal analysis and elasto-plastic time-history analysis. Employing the control variable method, the study first determined the key structural parameters of the corrugated web steel frame: specifically, a web thickness of 2 mm, a corrugation angle of 45°, a wavelength of 240 mm, and a wave height of 30 mm. Subsequently, a three-story frame model was constructed based on these parameters, and the structure’s seismic performance under the El Centro and Taft seismic waves was analyzed. The results demonstrate that the three-story corrugated web steel frame system exhibits excellent hysteretic energy dissipation capacity under low-cycle reversed loading. Structural deformation is dominated by lateral displacement, with the peak interstory displacement reaching 3.76 times the longitudinal displacement. The second floor is identified as the structural weak link. Compared with the Taft wave, the El Centro wave exerts a more significant influence on the structure’s dynamic response and induces more pronounced displacement and stress responses under the same seismic intensity.OPEN ACCESS Received: 15/10/2025 Accepted: 12/12/2025 Published: 20/03/2026

• Research on the identification of modulus parameters for rigid pavement panel foundations

  Abstract

  Based on the Pasternak two-parameter foundation model, this study establishes a dynamic model for analyzing the deflection of slabs under moving loads. The variational method and reciprocal equal work theorem are employed to obtain the deflection solution, while the Matlab program is utilized with practical examples to calculate the foundation response modulus considering transfer shear force, bending moment, and their combined effects. By fitting measured dynamic deflections with theoretical predictions using the least square method, the response modulus K of the foundation is determined, demonstrating that our proposed model effectively captures the realistic behavior of rigid pavements.

• Research on seismic performance of corrugated web rigid structures

  Abstract

  Corrugated web H-beam refers to a steel beam with a wavy shape along its length, which is extensively utilized in various parts of building structures such as beams, columns, and walls. It serves the purpose of connection and support, while the corrugated or folded design enhances the shear resistance and out-of-plane stiffness of the web to some extent. However, despite their advantages including high strength, stiffness, and lightweight construction, relevant regulations stipulate that these members can only be used in lower-intensity applications or higher-intensity scenarios if specific conditions are met. One crucial condition is that the ratio between the design value of axial force subjected to seismic action and the product of the member's flange section area and steel's tensile strength should not exceed 0.4. In this study, we aim to further investigate the seismic characteristics and applicable intensity of corrugated steel structures under earthquakes through large-scale finite element ABAQUS simulations. We will observe dynamic characteristics and failure modes of corrugated rigid frame structures using elastic-plastic time-history analysis methods as well as examine plastic deformation features of steel beam members under low cyclic loads via hysteretic analysis methods. The findings demonstrate that when properly designed with reasonable beam spans, corrugated web rigid frame structures can still be employed in high-intensity areas above 7 degrees even when subjected to an axial compression ratio up to 0.5.
