Flexural performance of round-ended concrete-filled steel tubular specimens J. Constr. Steel Res. (IF 4.1) Pub Date : 2024-02-12 Jun-Tao Guo, Zhi-Bin Wang, Ee Loon Tan, Yang-Hong Gao
Round-ended concrete-filled steel tubular (CFST) columns have numerous benefits, including easy construction, aesthetic appearance, and variable section arrangement. This study experimentally and numerically investigated the flexural behavior of round-ended CFST columns. The six testing results showed that as the aspect ratio increased from 1.38 to 1.86, the flexural resistance and stiffness increased

Coupled propagation behavior of multiple fatigue cracks in welded joints of steel-bridge J. Constr. Steel Res. (IF 4.1) Pub Date : 2024-02-10 Naiwei Lu, Honghao Wang, Jing Liu, Yuan Luo, Yang Liu
Fatigue cracking in welded joints is a critical problem in bridge engineering, especially for aging long-span steel bridges. The crack size and density are increasing gradually with the bridge aging process, where the crack interaction will accelerate the crack propagation or even short cracks merging into a long crack. However, the mechanism underlying the coupled propagation behavior of multiple

Axial compression behavior of coal gangue coarse aggregate concrete-filled steel tube stub columns J. Constr. Steel Res. (IF 4.1) Pub Date : 2024-02-10 Jinli Wang, Yongxu Duan, Xuetao Lyu, Yang Yu, Jiaxuan Xiao
To investigate the load-strain curves and failure modes of spontaneous-combustion coal gangue coarse aggregate (SCGCA) concrete-filled steel tube (CFST) stub columns under axial compression, 36 SCGCA CFST specimens and 18 comparative SCGCA concrete specimens were firstly tested with various SCGCA replacement ratios, concrete strengths and steel tube thicknesses. The results reveal that the bearing

Out-of-plane flexural behavior of assembled composite shear wall J. Constr. Steel Res. (IF 4.1) Pub Date : 2024-02-10 Ying Wang, Cuifen Dong, Zhichao Lai, Chenxi Fang, Junbo Zuo, Yuxing Yang
This study experimentally investigated the out-of-plane flexural behavior of assembled composite walls (ACWs). An experimental database was established, and seven specimens were tested. The effects of several parameters were investigated, including steel plate thickness, distance between two steel plates, and external concrete layer thickness. The results showed that ACW specimens exhibited promising

Experimental evaluation of a U-shaped steel plate as a seismic fuse J. Constr. Steel Res. (IF 4.1) Pub Date : 2024-02-09 Ahmed Mowafy, Ali Imanpour, Ying-Hei Chui, Hossein Daneshvar
This paper evaluates experimentally the cyclic response of a novel U-shaped steel plate proposed to dissipate seismic-induced energy through a unique mechanism called scissor bending. The cyclic behaviour of the U-shaped plate, including hysteresis response, plastic mechanism, strength and stiffness, ductility and energy dissipation capacities are examined. Four U-shaped steel plates varying in thickness
