Seismic Ductility Demands Predicted by Alternate Models of Building Frames

Earthquake Spectra, 1994
Peak values of story ductility demands produced by earthquakes on several models of multistory rigid frames are evaluated by means of step-by-step nonlinear dynamic analysis of structural response to simulated ground motion time histories. The models studied include the basic rigid frame model with nonlinear behavior concentrated at plastic hinges ...

Estimation of system-level ductility demands for multi-story structures

Engineering Structures, 1997
System-level ductility is an essential factor for earthquake resistant design of structures. It is related to the response modification factor (or force reduction factor), commonly used in aseismic design procedures. The ductility demands for single-degree-of-freedom structures or individual structural members can be determined easily.

Ductility Demands on Self-Centering Systems under Earthquake Loading

ACI Structural Journal, 2005
This paper describes the seismic response of self-centering single-degree-of-freedom (SDOF) systems in the form of constant-R ductility spectra. Constant-R ductility spectra for self-centering SDOF systems are computed and compared with those of SDOF systems representing conventional reinforced concrete (RC) systems (represented as bilinear ...

Constant-ductility strength demand spectra for seismic design of structures

Earthquake Engineering and Engineering Vibration, 2005
In displacement-based seismic design, constant-ductility strength demand spectra (CDSDS) are very useful for preliminary design of new structures where the global displacement ductility capacity is known. The CDSDS can provide the required inelastic lateral strength of new structures from the required elastic lateral strength.

Connection Ductility Demand for Different Ductility Levels in Capacity Design of Multi-Storey CLT Buildings

2020
Current European building codes Eurocode 8 provide no information on the ductile behaviour and failure mechanisms of cross-laminated timber (CLT) structures. Structural ductility is a key property to ensure good seismic behavior of buildings, as it allows yielding of dissipative zones along the building height which consequently reduces the seismic ...

Ductility demands on buckling-restrained braced frames under earthquake loading

Earthquake Engineering and Engineering Vibration, 2003
Accurate estimates of ductility demands on buckling-restrained braced frames (BRBFs) are crucial to performance-based design of BRBFs. An analytical study on the seismic behavior of BRBFs has been conducted at the ATLSS Center, Lehigh University to prepare for an upcoming experimental program. The analysis program DRAIN-2DX was used to model a one-bay,

Demand and supply of ductility in steel shear connections

Journal of Constructional Steel Research, 1989
Abstract Major response characteristics of shear connections are discussed. Interactions of the shear force, bending moment and rotation are discussed. The beam line concept is refined to include the inelastic range of behavior of the beam. The refined inelastic beam lines are recommended to be used in predicting rotational ductility demand of steel ...

Dynamic Ductility Demand and Capacity Design of Earthquake-Resistant Reinforced Concrete Walls

SP-157: Recent Developments In Lateral Force Transfer In Buildings, 1995
Reinforced concrete structural walls may provide efficient earthquake-resistance in multi-story buildings. In Europe they are commonly combined with gravity load dominated slender columns whereby the entire horizontal action is taken by the walls.

Ductility demands of filtered earthquakes on reinforced concrete frames

2008
The Mexico City 1985 and the Loma Prieta 1989 earthquakes demonstrated the destructive nature of seismic waves filtered through soft soils. Key characteristics of filtered ground motions are generally amplified acceleration, increased predominant period, and lengthened duration of strong shaking. Filtering of seismic waves through the soft soils in the
