ΑΠΑΙΤΟΥΜΕΝΟΣ ΣΥΝΤΕΛΕΣΤΗΣ ΕΝΔΟΤΙΚΟΤΗΤΑΣ ΜΟΝΟΡΟΦΟΥ ΕΚΚΕΝΤΡΟΥ ΣΥΣΤΗΜΑΤΟΣ ΕΔΡΑΖΟΜΕΝΟΥ ΣΕ ΠΑΡΑΜΟΡΦΩΣΙΜΟ ΕΔΑΦΟΣ ΚΑΙ ΥΠΟΚΕΙΜΕΝΟΥ ΣΕ ΟΡΙΖΟΝΤΙΑ ΣΕΙΣΜΙΚΗ ΔΡΑΣΗ
THE DUCTILITY DEMAND OF THE RESISTING ELEMENTS OF ECCENTRIC STRUCTURES SUBJECTED TO HORIZONTAL SEISMIC MOTIONS IS PRESENTED. IT IS FOUND THAT ONE OF THE MOST SIGNIFICANT PARAMETERS OF THE SYSTEM IS THE APPLICATION POINT OF THE TOTAL DESIGN FORCE. THE INFLUENCE OF ELASTICITY OF THE FONDATION SOIL ON …

Performance-based seismic engineering of low and medium-rise steel frames
… response parameters such as, interstory drift, ductility demand, and dissipated hysteretic energy are obtained. In addition, a modified form of Park-Ang damage index is calculated for moment-resisting frames. The seismic performance of the steel frames is assessed in accordance with the …

Connections to concrete-filled steel tubes
… studied, and the connections with the highest ductility demand were isolated. The second phase of the research was devoted to the inelastic finite element analysis of several connection details. A 3-D finite element model was developed for each connection detail. The parameters used in the …

Effect of Viscous Fluid Dampers on Steel Moment Frame Designed for Strength and Hybrid Steel Moment Frame Design
… for low intensity gentle earthquakes. The ductility demand IDA study proves that as the frames become more hybrid, the ductility demand increases for the special detailing frame, where plastic capacity was reduced, and decreases for the ordinary detailing frame, where the plastic capacity …

A monitoring method for after-earthquake damage evaluation of buildings
… of a structure after an earthquake is the ductility demand expressed in terms of interstory drift. The use in monitoring systems of this indicator is examined in this thesis through case studies on reinforced concrete framed buildings and precast industrial buildings. In the design process …

Assessment of Foundation Rocking Behavior in Reducing the Seismic Demand on Horizontally Curved Bridges
… the effect of rocking on columns with different ductility capacities concluded that bridges designed with rocking foundations have less ductility demand than bridges with conventional columns. This gives the ability to reduce the transverse reinforcement ratios in the columns and still sustain …

Ductility demands of filtered earthquakes on reinforced concrete frames
… strengths are required to maintain a certain ductility. These results were indicated by the response of single-degree-of-freedom, elasto-plastic systems in time-step computer analyses. They can also be predicted reasonably accurately by the R-μ equation, a relationship derived from energy …

Parameters Influencing Seismic Structural Collapse with Emphasis on Vertical Accelerations and the Possible Related Risks for New and Existing Structures in the Central and Eastern United States
… by P-Delta effects (rp) in conjunction with the ductility demand was the best predictor of collapse. These two quantities include all four structural parameters and the seismic displacement demands. It was also discovered in the parameter study that vertical accelerations did not significantly …
