large panel precast structures are analyzed based on the connection rigidity. however, the connections undergo nonlinear and inelastic response, when subjected to seismic loads. thus, to study the actual behavior of structure, the connection nonlinearity should be implemented in the joints. in this paper, three conventional connection types are modeled based on the envelope of their cyclic resp...

Acase studywas conducted to investigate the seismic behavior of steel plate shear walls having boundary elements designed by two different philosophies. The first design approach does not guarantee that formation of in-span plastic hinges on horizontal boundary elements (HBEs) will be prevented, whereas the second approach guarantees that plastic hinges can only occur at the ends of HBEs. Pusho...

composite couple beams are the concrete elements consisting of longitudinal bars and steel plate, therefore suitable for shear transferring in couple shear walls with arranged gates in its height. in this paper, after modeling couple beams with and without steel plates with f.e methods and calibration the models with experimental results, effects of parameters such as thickness, height, length ...

Consistent with capacity design principles and requirements of ductile behavior, the 2005 AISC and 2001 CSA seismic design codes require that the intermediate horizontal boundary elements HBEs of steel plate shear walls SPSWs be designed to remain essentially elastic with the exception of plastic hinges at their ends when the infill plates fully yield under seismic loading. However, the unexpec...

damages due to northridge and kobe earthquakes were expressive of considerable effects of vertical components of earthquakes compared to the horizontal ones. on the other hand, thin steel plate shear wall is one of the newest resistant systems which until now it`s behavior haven’t been investigated under vertical component of earthquake. therefore, in this article, effects of vertical component...

This article describes molecular dynamics simulations of an ionic liquid (IL) confined between iron oxide surfaces under relatively high pressure and severe shearing, representative of a typical steel-steel lubricated contact. The simulations reveal the presence of hydrodynamic and thermal slip at the walls, despite the wetting nature of the fluid/wall interface. A crucial consequence of the te...

A common lateral force resisting system for cold-formed steel (CFS) buildings consists of shear walls sheathed with oriented strand board (OSB). Previous experimental and computational research on CFS shear walls, as well as those with other framing materials, has demonstrated that the complex interaction of the fasteners with the sheathing is an important factor in the nonlinear behavior of th...

Coupling beams are considered one of the most important structural elements due to their vital role in resisting lateral loads by improving overall building stiffness and reducing impact overturning. The resistance coupled shear walls (CSWs) earthquakes depends on coupling beam (CB) for enhancing ductility system energy absorption capacity. There two main types beams; diagonally reinforced conv...
