Abstract A novel type of angle steel buckling‐restrained brace (ABRB) has been developed for easier control on initial geometric imperfection in the core, more design flexibility buckling restraining mechanism and assembly work. The core is composed four steels to form a non‐welded cruciform shape restrained by two external steels, which are welded longitudinally an tube. Component test was conducted seven ABRB specimens under uniaxial quasi‐static cyclic loading. results reveal that...
In a previous study by the authors, cyclic behavior of novel type pin-connected angle steel buckling-restrained brace (ABRB) was examined, and failure mechanism in core projection ABRB induced an excessive bending effect caused end rotation discussed. this paper, occurrence modes are first investigated based on test results, which shows that demands would be significantly increased with presence gap additional could observed if were large enough to cause two-point contact at ends. Then, new...
This study explores the causal relationship between sedentary behavior and urological cancers, focusing on bladder cancer (BC), prostate cancer, kidney using Bayesian Mendelian randomization mediation analysis. A two-sample (MR) framework was employed, genetic variants as instrumental variables. multivariate MR assessed effects of behaviors (TV watching, computer use, driving) cancers. Sensitivity analyses (MR-Egger, MR-PRESSO, Cochran Q ) ensured robustness. Mediation analysis identified...
The main objective of this study is to improve the performance ultrafine dredged sand mortars by using metakaolin (MK) and silica fume (SF) mixed with high-content FA. mechanical properties microstructure were analyzed. results show that strong growth rate 5%, 10%, 15% MK SF contents, respectively, exceeds 30% at age 7 d. Compared an ordinary Portland cement mortar, shrinkage specimens 5% increases prior d decreases 16.9% 13.8%, 90 addition shows a better enhancement effect than SF,...
Summary In‐plane buckling‐restrained brace (BRB) end rotation induced by frame action is a commonly observed phenomenon in braced frames (BRBFs). However, its effect on BRB connection behavior has not yet been clear. In this study, four deformation modes for quick determination of rotational demand are proposed non‐moment BRBF considering different arrangements, installing story BRBs, and boundary condition corner gussets connected with column base. Key factors affecting flexural moments...
To prevent lower-order local buckling of H-section steel core, an improved type buckling-restrained braces named brace with core was proposed by the authors. This article further investigates effect configuration details on seismic performance and compares two half-wavelength calculation methods for higher-order core. First, quasi-static cyclic tests are described newly designed cores another flat Then, Bleich’s Lundquist’s reviewed evaluating half wavelength based elastoplastic theory...
