Application of Inelastic Design Spectrum to Capacity-Demand-Diagram Methods
An improved capacity-demand-diagram method that uses the well-known constantductility design spectrum for the demand diagram is developed and illustrated by examples. This method estimates the deformation of inelastic SDF systems consistent with the selected inelastic design spectrum, while retaining the attraction of graphical implementation of the ATC-40 Nonlinear Static Procedure.
متن کاملSeismic Fragility Assessment of Special Truss Moment Frames (STMF) Using the Capacity Spectrum Method
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...
متن کاملA new method for drawing the capacity spectrum for seismic analysis and structural rehabilitation
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...
متن کاملevaluation of accuracy of capacity spectrum and improved capacity spectrum methods for determination of performance of concrete frames
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...
