ELEC COMMUNICATIONS CORP., Norwalk, Conn., a local and long-distance provider, said it would acquire the closely held Line One Inc., New York, a telemarketing company, to gain access to the company's marketing and call-center capabilities.
Exact, unique, closed form formulae have been provided to assess the collapse prevention and self-centering capabilities of the system.
SMAs also possess unique characteristics such as good energy dissipation, excellent re-centering capabilities and corrosion resistance.
The SC frame utilizes post-tensioned (PT) beam column connections and column foundation connections to provide the re-centering capabilities after earthquakes.
This paper extends previous works concerning electrostatic handling by adding new theoretical and FEM models, further tests, and new interpretations of the gripper's grasping and centering capabilities.
A hybrid seismic device that provides both energy-absorbing and re-centering capabilities to overcome external forces is developed and evaluated.
By using pre-strained wires, this design focuses on maximizing energy dissipation, partially relinquishing the re-centering capabilities of the device.
Results obtained through the seismic analysis reveal that the hybrid braced frame system exhibits a similar energy dissipation capacity to the buckling restrained braced system, while also having excellent re-centering capabilities.
Two large-scale PS-SCED braces with different types of inner tube members are designed, fabricated, and tested under low cyclic reversed loadings, and the results demonstrate that the PS-SCED braces exhibit stable and repeatable flag-shaped hysteretic responses with excellent self-centering capabilities, effective energy dissipation, large ultimate bearing capacity, and appreciable ductility.
