the objective of this review to be submitted in two independent parts, for steel frames and for rc frames, is to compare their structural performance with respect to the proposed n2-method, and so also of the consequent convenience of using pushover methodology for the seismic analysis of these structures. a preliminary investigation is presented on a pushover analysis used for the seismic perf...

The present study sets out to integrate the performance-based seismic design approach with the connection topology optimization method. Performance-based connection topology optimization concept aims to simultaneously optimize the size of members and the type of connections with respect to the framework of performance-based seismic design. This new optimization concept is carried out for unbrac...

A new vibration control system, Damped braced tube is developed for adopting on super high-rise buildings in central Tokyo. This system consists of frame using elastic braces and damped slit where a portion are replaced by dampers. acting as link beam coupled shear wall can dissipate seismic energy very efficiently contribute to succeeding meet higher criteria. paper describes outline efficienc...

This paper proposes a new type of variable-cross-section replaceable link that can isolate the plastic deformation. The and frame beam connect with expanding section by bolt along flange web separately. It is easy to design an elastic bolt, reduce slippage, facilitate replacement after earthquake. Considering large deformation range high-strength steel superior link, eccentrically braced variab...
