Study on the calculation method of the maximum number of bonded steel plates at the bottom of reinforced concrete beams

Lifeng Wang, Fei Yu, Ziwang Xiao, Qi Wang

When the reinforced concrete beams are reinforced by bonding steel plates to the bottom, excessive use of steel plates will make the reinforced concrete beams become…

Seismic behaviour of the non-straight steel beams in the structural plans

Farshid Rashidiyan, Seyed Rasoul Mirghaderi, Saeed Mohebbi, Sina Kavei

This research study focuses on investigating the seismic performance of non-straight beams in steel structures and exploring the mechanism by which plastic hinges are formed…

Research on fatigue curve fitting methods based on the notch stress approach

Shengfu Xue, Zhengping He, Bingzhi Chen, Jianxin Xu

This study investigates the fitting techniques for notch fatigue curves, seeking a more reliable method to predict the lifespan of welded structures.

Evaluation of the strain response of FRP partially confined concrete using FEM and DIC testing

Yunfei Zou

This study aims to enhance the understanding of fiber-reinforced polymer (FRP) applications in partially confined concrete, with a specific focus on improving economic value and…

Influence of pre-existing cracks and concrete cover on service life of reinforced concrete and mechanical behaviour of corroded rebars

Kuleni Fekadu Yadeta, Sudath C. Siriwardane, Tesfaye Alemu Mohammed, Hirpa G. Lemu

Incorporating pre-existing crack in service life prediction of reinforced concrete structures subjected to corrosion is crucial for accurate assessment, realistic modelling and…

Free vibration characteristics of elastic foundation-supported porous functionally graded nanoplates using Rayleigh-Ritz approach

Azmeera Sudheer Kumar, Subodh Kumar, Prashant Kumar Choudhary, Ankit Gupta, Ashish Narayan

The purpose is to explore the free vibration behaviour of elastic foundation-supported porous functionally graded nanoplates using the Rayleigh-Ritz approach. The goal of this…

The influence of CMT-MAG and MAG welding-processes on microstructure and mechanical behaviour of C-Mn E410 structural-steels

Akhil Khajuria, Anurag Misra, S. Shiva

An experimental investigation for developing structure-property correlations of hot-rolled E410 steels with different carbon contents, i.e. 0.04wt.%C and 0.17wt.%C metal active…

A method for modifying octagonal Goodman–Smith fatigue limit diagram

Yuhan Tang, Yuedong Wang, Jiayu Liu, Boya Tian, Qi Dong, Ziwei He, Jiayi Wen

In order to extend the application of the original octagonal Goodman–Smith fatigue limit diagram, which is commonly used for the evaluation of structure fatigue stress in…

Investigation into the interface bond between polyurethane concrete and steel plate

Yuxuan Wu, Wenyuan Xu, Tianlai Yu, Yifan Wang

Polyurethane concrete (PUC), as a new type of steel bridge deck paving material, the bond-slip pattern at the interface with the steel plate is not yet clear. In this study, the…
