In order to investigate the seismic performance of prestressed concrete rocking frame (PCRF), a theoretical model based on rigid body is established for one-story single-span PCRF. The PCRF studied in this paper has connecting interfaces set at column feet and inner faces beam–column joints, allowing columns be uplifted with accompanying separation interface rotation beam around interface. tend...

In the last decades, high priority has been given by research community to development of low-damage structures, and reparability become fundamental for minimizing environmental economic impact reconstruction. this context, European Research Fund Coal Steel (RFCS) project DISSIPABLE was carried out, with aim test large-scale structures where dissipation is concentrated on replaceable components...

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...

Concentrically braced frame (CBF) systems are susceptible to buckling (which causes a decrease in energy absorption), although this system has considerable lateral stiffness and strength. To over shortcoming, researchers have suggested the use of I-shaped steel dampers as practical idea that prevents increases absorption but reduces system. increase damper, thickness web or flange can be increa...

This paper examines the seismic behaviour of steel Multi-Tiered Concentrically Braced Frames (MT-CBFs) Conventional Construction category (Type CC) in moderate regions eastern Canada and proposes a new design method for such structures. A total 32 prototype MT-CBFs part single-storey building are selected designed accordance with 2019 Canadian standard (CSA S16-19) provisions Type CC structures...
