Seismic Vulnerability Analysis for Multi-Story Ancient Wooden Buildings Based on Multi-Level Engineering Demand Parameters

Yuhang Li, Yang Deng, Aiqun Li

Multi-story ancient wooden buildings — repositories of humanity’s architectural heritage — are highly vulnerable to seismic events owing to their complex configurations, material properties, and accumulated historical service effects. However, existing evaluation frameworks often fail to account for their unique structural characteristics …

Experimental and Finite Element Analysis of the Built‐Up Hot‐Rolled Channel Steel Beams

Ruijun Zhang, Junhong Lu, Yifeng Wu, Ming Jing et autres

ABSTRACT Built‐up hot‐rolled channel steel beams are crucial for modern construction due to their excellent structural efficiency, yet existing studies mainly focus on cold‐formed thin‐walled built‐up beams, leaving gaps in understanding the bending performance of hot‐rolled counterparts. This study investigates the flexural …

Experimental Study on Tensile-Shear Fatigue of Bolts

Baoya CAO, B. Yang, Aiqun Li, Yang Deng

In practical engineering structures， bolts often operate under tensile-shear combined stress states， whereas current design codes only provide calculation methods for bolt fatigue life under pure tension or pure shear loads. Therefore， this study conducted tensile-shear fatigue tests on bolts using a …
