The results of the structural engineering field of Hefei University of Technology won the selection of special articles awards for the editor -in -famous journal editor

近日，合肥工业大学土木与水利工程学院王静峰教授团队在结构工程领域著名期刊《Structures》上发表题为“Seismic fragility analysis of CFT frames with buckling-restrained braces and steel braces under long- and short-duration ground motions "Research papers. The thesis won the Editor-in-Chief ’s Featured Art (editor-in-chief selected characteristic article) awarded by the editor-in-chief of Structures and the Royal Institute of Engineering. Professor Wang Jingfeng of the school is the first author and a doctoral student Li Beibei as the second author. The work has been funded by the National Natural Science Foundation of China and a collaborative project of Anhui University.

Earthquake disasters are sudden and unpredictable, and severe secondary disasters will have a significant impact on society. The flexion constraint support, as a widely used energy -consuming shock absorption component, has the dual function of carrying and energy consumption. Under the action of large earthquakes, you can use axial stretching and yield to consume seismic energy to reduce damage to the main structure. The prefabricated combination structure composed of the context of the flexion constraint support and the steel pipe concrete is in line with the development trend of my country's construction industrialization, which helps enhance the resilience of the city's seismic resistance. However, key issues such as performance of earthquake resistance design, general support and flexion constraint support, the impact of the earthquake during earthquakes, and probability of earthquake damage damage in need need to be resolved urgently.

Professor Wang Jingfeng's research team proposed a plastic seismic design method based on improved energy balance and the overall failure mode, and developed a prefabricated steel pipe concrete framework-flexion constraint support structure probability earthquake-like damage analysis method based on incremental power analysis method. Preferred damage factors can clarify the effects of impact on the accumulation of structural accumulation when the seismic is held. The comprehensive seismic intensity indicators that consider the comprehensive seismic intensity associated with the spectrum formation effect associated by the effectiveness, adequateness, and robustness analysis. Research results are instructed to the performance of the combination framework-flexion constraint support structure when the occurrence of earthquake anti-seismic design and earthquake movement-cumulative damage association.

According to reports, in recent years, Professor Wang Jingfeng's research team has continued to publish in the field of civil engineering engineering, ENGINEERING Structures, Structures, Journal of Constructure Steel Research, Journal of Civil Engineering, Journal of Architecture Structures, etc. Support, wall -type metal damping device) and its connection structure measures with concrete/steel frame structures and rotation performance, collaborative seismic characteristics, performance design methods, probability earthquake damage and other important research results; With full affirmation of internationally renowned scholars such as Australia. The Standardization Association of the China Engineering Construction Standardization Association "The Technical Regulations of the Excellence Restrictions on the Restrictions" (T/CECS817-2021), the editor-in-chief of the local standard of Anhui Province "Technical Regulations for the Fresh Confusion Supporting Structure" (DB34/T 5069-2017) and the "Building Wall Style Style) Metal damping technical regulations (DB34/T 3957-2021), etc.; Research results were successfully applied to many projects such as Haikou Meilan International Airport.
