Shaking table tests on the 1/4th-scale three-story reinforced concrete frames were carried out to investigate the effects of bidirectional earthquake motions on overall nonlinear response of reinforced concrete frame buildings. Two identical models were constructed and one was subjected to bidirectional horizontal earthquake motions and the other was subjected to unidirectional one. A series of...

The steel column performance in realistic structures during a fire has yet to be fully understood because existing research emphasizes single-story performance, thereby disregarding the influence of continuous columns multi-story configurations devoid fire. This paper presents numerical study comprehend overall structural columns, considering effect loading ratios, restraint continuity, and sin...

According to the St. Louis POST-DISPATCH, Monsanto, the St. Louis chemical and biotechnology giant, last month announced it had recalled "small quantities" of a genetically engineered canola seed containing an unapproved gene that had gotten into the product by mistake. Canola is a crop grown for livestock feed, and for oil consumed by humans. The canola-recall story, only 84 words long, was bu...

When we were given the challenge of expressing our views of research as the researcher‟s story, we intended to talk primarily about the ways in which our personal lives mediated our research work. While this remains one of the aspects of what we want to share, in our negotiations and conversations about writing this column we became aware of what brought us together to write a common article on...

This paper compares base shears computed from floor accelerations (inertial base shear) and column shears (structural base shear) for two mid-rise, multi­ story buildings due to a suite of 30 earthquake ground motions. The presented results demonstrate that the inertial base shear exceeds the structural base shear in the median by 10% to 20% and may exceed the structural base shear by as much a...

This paper contains the motivation for the study of critical surfaces in [2]. In that paper, the only justification given for the definition of this new class of surfaces is the strength of the results. However, when viewed as the topological analogue to index 2 minimal surfaces, critical surfaces become quite natural.

In this study, it is aimed to investigate the effect of different soil classes on behavior structure under earthquake loads. An evaluation was made for five-storey and eight-story reinforced concrete (RC) frame structures considering three (ZC, ZD, ZE) defined in Turkish Building Earthquake Code 2018 (TBEC 2018) current hazard Sakarya. structural system RC frame, cross-section geometry reinforc...
