Ductility Demand on Steel Reinforcing Bars in Concrete Buildings

Civil-Comp Proceedings, 2012
According to actual Italian and European standards for constructions, reinforced concrete buildings in seismic areas should be designed following the capacity design approach, in order to dissipate seismic energy through the development of plasticisations located in particular areas, providing global collapse mechanisms and avoiding premature failures ...

Reliability-based constant-damage ductility demand spectra of mid-rise RC building structures using modified equivalent linearization method

Lecture Notes in Civil Engineering, 2019
In the displacement-based seismic design and evaluation, the equivalent linearization method is one of the approximation methods to estimate the maximum displacement response of a single-degree-of-freedom (SDOF) system.

Predicted Ductility Demands for Steel Moment Resisting Frames

Earthquake Spectra, 1989
Recent changes to the United States seismic design provisions permit the use of weak column-strong beam steel moment resisting frames. This design concept has not been used in the past, because it results in plastic hinges in the columns during moderate or extreme earthquakes.

BUILDING DUCTILITY DEMAND: INTERPLATE VERSUS INTRAPLATE EARTHQUAKES

Earthquake Engineering & Structural Dynamics, 1996
The inelastic seismic response behaviour for a range of simplified single-degree-of-freedom models has been analysed using 180 random phase angle synthetic accelerograms with different frequency contents and different durations and 105 real accelerograms collected from different regions worldwide.

Ductility demand spectra for marine structures characterized by the self-centering system with the flag-shaped model under offshore ground motions

Advances in Structural Engineering
Previous seismic designs of marine structures usually adopted onshore ground motion. However, the response of marine structures under onshore and offshore ground motions are marked differences.

Ductility demand estimation of high-rise steel special moment frames due to structure-pile-soil interaction

Geomechanics and Geoengineering
This study is concerned with variation of ductility demands in a range of tall buildings comprising 15, 20, 25, and 30-story steel special moment frames resting on pile groups in a flexible soil medium.

Performance-Based Seismic Design for Bridge Bents Retrofitted with BRBs Using the Ductility Demand Spectra of SDOF Oscillators with Bilinear Fuses

Journal of earthquake engineering
Reinforced concrete bridge bents with double columns in bridge substructures are commonly used, but it has suffered severe damage during strong earthquakes.

Seismic Column Demands in Ductile Braced Frames

Journal of Structural Engineering, 2009
In ductile braced frames, column seismic demands depend on the strength of ductile elements and yielding patterns that occur during earthquake loading. Column demands were investigated in buckling restrained braced frames (BRBFs), special concentrically braced frames (SCBFs), and eccentrically braced frames (EBFs) with different heights (3, 9, and 18 ...

Seismic shear demand of ductile cantilever walls: a Canadian code perspective

Canadian Journal of Civil Engineering, 1994
During severe earthquakes, ductile flexural walls are expected to exhibit inelastic flexural behaviour while other brittle deformation mechanisms, such as shear, should remain elastic. The philosophy of the Canadian seismic provisions for flexural walls is based on the assumption that the force reduction factor is applicable to both flexure and shear.

Beam Strength Enhancement at Design Ductility Factor Demands

Journal of Structural Engineering, 1990
A refined bending‐analysis model is presented that accurately predicts available experimental results. By means of this model, the relations of the ultimate‐to‐yielding moment ratio versus the longitudinal reinforcement ratio are deduced for a beam that is rectangular in cross section with two reinforcement layers. Two values of the curvature‐ductility
