the present study is concerned with the simultaneous optimization of the size of components and the arrangement of connections for performance-based seismic design of low-rise spsws. design variables include the size of beams and columns, the thickness of the infill panels, the type of each beam-to-column connection and the type of each infill-to-boundary frame connection. the objective functio...

The NIST RoboCrane is a cable-suspended robot with the potential to reduce the disadvantages of conventional cranes. One weakness of the RoboCrane is the need for at least three fixed rigid support points for the six overhead cable connections. In many potential applications, these rigid support points are simply not available. This article presents a new RoboCrane support concept based on rigi...

UNLABELLED The aim of this study was to carry out a bibliographic review of all available literature addressing the issue of whether or not the connection of teeth to implants by means of a prosthesis is a viable treatment alternative. Twenty articles from a variety of sources were analyzed and classified in order to draw conclusions. Articles were classified by type and an analysis was made of...

1. Abstract In this paper, a genetic algorithm is proposed for discrete minimal weight design of steel planar frames with semi-rigid beam-tocolumn connections. The frame elements are constructed from a predetermined range of section profiles. Conventionally, the analysis of frame structures is based on the assumption that all connections are either frictionless pinned or fully rigid. Recent lim...

Connections of I-beam to CHS column in buildings are either simple (fin plate connection, directly welded beam connections) and flexible or rather complex rigid (external diaphragm connections). The passing-through I-beam-to-CHS connections made by laser cutting technology offer a solution that limit the amount welding enhance stiffness joint. An experimental campaign has been carried out inves...
