Evaluation of strategies for seismic design
Current trends in seismic design require a new approach, oriented in satisfying motion related design requirements and limiting both structural and non-structural damage. Seismic isolation and damping devices are currently used in buildings as two innovative performance-based design approaches. …

High-performance braces for seismic design
… challenge for the structural engineer in designing earthquake-resistant structures is to design buildings with both adequate ductility and sufficient stiffness. Traditional lateral force resisting systems such as the moment resisting frame and the concentrically braced frame are both …

Displacement-Based Seismic Design of Timber Structures
The research is aimed at developing seismic methods for the design and evaluation of the seismic vulnerability of wooden structures, using a displacement-based approach. After a brief introduction on the seismic behaviour of timber structures, the general Direct Displacement-Based Design …

Seismic Design Studies of Low-Rise Steel Frames
… is dependent on several parameters such as design base shear, beam-to-column strength ratio, moment-resisting connection behavior, nonstructural element participation, etc. The influence of these parameters was determined by performing inelastic time-history analyses.

Investigation of alternative seismic design procedures for standard buildings
"The seismic design provisions of most building codes in the United States specify ground motion parameters for various regions of the country and provide simple formulas to determine a distribution of lateral forces for which the structure should be designed. The simple formulas typically involve …

Prediction of seismic design response spectra using ground characteristics
… are carried out for each group. Smoothed design spectra for relative and pseudo velocities and relative acceleration responses of single degree of freedom oscillators and the velocity and acceleration responses of massless oscillators are proposed for each group. Methods to predict …

Seismic design and analysis of hybrid masonry with fuse connectors
… of this system has been limited to low seismic regions where wind loads tend to control the design of the lateral force resisting elements. To establish a fundamental understanding of seismic behavior for hybrid masonry structural systems, simple analytical models are developed to …

Decision making under epistemic uncertainty : an application to seismic design
… effects of these factors for the case of optimal seismic design of buildings. Results show that when temporal fluctuations in the epistemic uncertainty and regulatory safety constraints are included, the optimal level of seismic protection exceeds the normative level at the time of construction. …

A performance based approach for seismic design with hysteretic dampers
… is the development of a preliminary motion-based design methodology for the use of these devices in mitigating damage to structural and non-structural elements. In this regard, a shear beam idealization for a typical 1 0-story steel building is adopted and nonlinear dynamic response of the …

Stochastic and seismic design response of linear and nonlinear structures
New methods for calculating the stochastic and seismic design response of linear and nonlinear structures are presented. For linear structures, two approaches are developed: (1) the modified mode displacement approach for classically as well as non-classically damped structures, and (2) the …

Seismic design of energy dissipation systems for optimal structural perfromance
… of structural systems. However, systematic design procedures for optimal sizing and placement of these protective systems in structural systems are needed and are not yet available. The main objective of this study is, therefore, to formulate a general framework for the optimal design of …

Advanced Seismic Design of Innovative Precast Systems for Structural Response Control
Emerging Design Philosophy. In current design philosophy a key concept is ductility, a parameter that reflect intrinsic energy dissipation capacity of structural elements. The key concept is the reduction of the structural cost, from the point of view of the initial cost, for design under moderate …

Seismic Design and Evaluation of Multistory Buildings Using Yield Point Spectra
A method to estimate peak displacement response and interstory drift indices of multistory buildings using YPS and establish SDOF formulations is also presented. The method may be considered a new nonlinear static procedure (NSP). Interstory drift indices (IDIs) are estimated using deformed shapes …
