Economic performance analysis of seismic isolation, energy dissipation, and traditional seismic structures

Seismic performance of transportation structures

Revolutionary changes which have taken place in the USA over the past 50 years in earthquake engineering as applied to transportation structures (highway bridges, and transit and high-speed rail aerial structures) are reviewed, giving emphasis to seismic design criteria, characterization of seismic ground motions, dual strategy of seismic design, modelling and dynamic analysis, assessment of se...

Seismic Design and Analysis of Structures

The problem of estimating the power spectra of non-stationary stochastic processes by using the harmonic wavelet transform is addressed in this paper. Conventional spectral analysis provides spectral coefficients that are averaged over time and thus, does not represent the evolutionary behavior of power spectra of non-stationary processes. In this study, evolutionary power spectrum of a non-sta...

Seismic Risk of Structures and the Economic Issues of Earthquakes

Seismic Behavior and Dissipated Plastic Energy of Performance-Based-Designed High-Rise Concrete Structures with Considering Soil–Structure Interaction Effect

Since the structure and foundation are built on soil, the soil is the major platform by which seismic vibrations are transmitted to the structure, and has noticeable effects on the response and behavior of structure during earthquakes. In this research, the recently introduced Performance-based plastic design (PBPD) and its modified Performance-based plastic design (MPBPD) method in which soil ...

Performance Based Seismic Retrofit of Masonry Infilled Reinforced Concrete Frames Using Passive Energy Dissipation Devices

The paper presents a plastic analysis procedure based on the energy balance concept for performance based seismic retrofit of multi-story multi-bay masonry infilled reinforced concrete (R/C) frames with a ‘soft’ ground story using passive energy dissipation (PED) devices with the objective of achieving a target performance level of the retrofitted R/C frame for a given seismic hazard level at t...
