Conventional concentrically-braced frame (CBF) systems have limited drift capacity before brace buckling and related damage leads to deterioration in strength and stiffness. Self-centering concentrically-braced frame (SC-CBF) systems have been developed to increase drift capacity prior to initiation of damage and minimize residual drift. SC-CBFs differ from conventional CBFs in that the SC-CBF ...

Setback irregularities are considered where discontinuity between adjacent stories is excessive. This irregularity caused the probability of high damage at structures subjected to strong earthquake motion. For this purpose, study was conducted by modeling steel special moment frame (SMF) using a finite element calculation program with nonlinear static analysis compared Padang city’s response sp...

Researchers awarded a considerable attention to progressive collapse analysis in recent years avoid the partial or entire failure of structures. General Service Administration guidelines (GSA) established base deal with such catastrophic failure. For multi-story building, these proposed column removal scenario which one more columns different locations should be removed from structure. Then, re...

Many recent research studies focused on the development of innovative seismic resilient structures by chasing objectives minimising both damage and repair time, hence allowing definition able to go back undamaged, fully functional condition, in a short time. In this context, present study investigates an type self-centring damage-free steel column base (CB) connection its beneficial effects whe...

SSI and site amplification effects are investigated as influences on the seismic fragility of existing reinforced concrete moment-resisting frame dual frame-wall system buildings supported shallow foundations without interconnecting beams. We build upon a holistic methodology that accounts for soil–foundation–structure interaction using modular approach. calculate curves based nonlinear dynamic...

In many regions of the world, a conventional low-ductility concentrically braced frame (CBF) is commonly chosen as seismic force resisting system. The energy dissipation not restricted to yielding and buckling braces, would be required for ductile frames; rather, assumed occur through localised friction in connections, well limited member yielding. objective this study was characterize by means...

This paper provides insight into a probabilistic demand analysis of steel-concrete structures equipped with novel dissipative components. DISSIPABLE components were studied in the framework European Research Fund for Coal and Steel (RFCS) project, funded to test large-scale which dissipation is concentrated specifically designed elements that act like fuse can easily be replaced after seismic e...
