recently, two of the authors have introduced the collapse capacity spectrummethodology, which allows the assessment of the collapse capacity of highly inelastic p-deltasensitive regular frame structures without performing non-linear time-history analyses. the mainingredient of this method is the collapse capacity spectrum, which represents the seismic collapsecapacity of an inelastic non-deteri...

performance seismic evaluation is an important topic in earthquake engineering. in this regard, several methods have previously been developed and used. the main objective of present research is to evaluate two methods including “capacity spectrum method (csm)” and “improved capacity spectrum method (icsm)” in determination of seismic performance of concrete frames. for this purpose, several sa...

fragility curves represent the probabilities that structural damages, under various levels of seismic excitation, will exceed the specified damage states by means of earthquake intensity damage relations. conceptual aspects related to seismic vulnerability, damage and risk evaluation are discussed first, together with a short review of the most widely used possibilities for the seismic evaluati...

A review of previous studies shows that there are two general views on how to determine demand in structures through incremental nonlinear static analysis. In the first view, multi-modal methods are used to determine demand in structures. In this view, the applied load pattern is applied to the structure according to the shape of each vibration mode, assuming that the structure deformation foll...

When earthquakes occur, structures sustain damages. But it is impossible to estimate damages exactly which occur in the structures because of the uncertainty of materials and ground motions. Therefore, probabilistic methods for estimating damages of the structures have been suggested lately. In this study, probabilistic capacity spectrum method expanding established capacity spectrum method is ...

Consider a multimedia input traac stream, described by a stationary random process. Our previous study indicates that second-order input statistics, which are described by power spectrum in the frequency domain, play a dominant role in queueing performance as compared with higher-order input statistics. In this paper we show the signiicant eeect of input power spectrum on link capacity allocati...

Since 2000, cognitive radio has slowly been moving from theory into reality. One major driving force for that is tangible commercial applications for cognitive radio, the most major of which is dynamic spectrum access (DSA). A wide variety of DSA techniques have been proposed, in an effort to take advantage of every ounce of unused spectrum. This paper analyzes the three main approaches: freque...
