Constant Ductility Site-Specific Yield Point Spectra for Seismic Design

Soft Soil Seismic Design Spectra Including Soil-structure Interaction

Design spectrum is known as an essential tool in earthquake engineering for calculation of maximum (design) responses in a structural system. Soil-structure interaction (SSI), as a phenomenon of coupling of responses of a structure and its underlying soil, was explored after introduction of design spectra and has not been taken into account in developing a design spectrum traditionally. To cons...

Determination of Yield Point and Ductility of Timber Assemblies: in Search for a Harmonised Approach

Knowledge of the yield point and ductility of a structure is important in seismic design. The yield point of an assembly is defined as a point where it begins to plastically deform, while ductility describes its ability to yield without substantial reduction in strength. These parameters can be determined from the analysis of the load-deformation curves resulting from destructive tests. To date...

Yield curvature for seismic design of circular reinforced concrete columns

Seismic Design of Steel Structures Based on Ductility and Incremental Nonlinear Dynamic Analysis

In this paper a simple tool for seismic design of steel structures for a selected ductility level is presented. For this purpose, a consistent set of earthquakes is selected and sorted based on the maximum acceleration of ground surface. The selected records are applied as the base motion to a single-degree-of-freedom system with strain hardening and the maximum response acceleration is determi...

The representation of P- effects using Yield Point Spectra

Yield Point Spectra are used to indicate the influence of Peffects on the lateral strengths associated with constant ductility demands. The intensity of Peffects is represented by a new index, termed the effective height, heff. This representation is useful for performance-based seismic design, because the effective height may be estimated accurately using information that is available early in...
