In the chapter it is shown that extended IDA is a simple yet efficient method for estimating the seismic response parameters, while taking into account the modelling uncertainties. The results can be used directly for the determination of the probability of exceeding a given limit state since the seismic response parameters are determined with consideration of both sources of uncertainties. Epistemic uncertainties can have an important influence on the dispersion and on the spectral acceleration capacity, which corresponds to global dynamic instability.
F.02 Acquisition of new scientific knowledge
COBISS.SI-ID: 5210209A PBEE toolbox for seismic performance assessment of reinforced concrete frames and bridges includes several functions which provide calculations of the moment-rotation relationship of plastic hinges in columns and beams, rapid determination of simplified nonlinear structural models, the post-processing of the OpenSees and structural performance assessment with different methods. As such, the PBEE toolbox can serve for code calibration, as a basis for new applications, e.g. for the design of structures based on nonlinear analysis or for parametric/probabilistic studies.
F.09 Development of a new technological process or technology
COBISS.SI-ID: 5106785For the purpose of environmental impact assessment we have assessed seismic risk for the gravity dam HE Učja with consideration of the limit state of the cracking of concrete, sliding and overturning of the dam. Seismic hazard maps were adopted in the risk study, while response of the dam was obtained by the nonlinear dynamic analysis. Results showed that the dam is safe since the estimated risk for collapse of the dam is practically negligible. Slightly higher risk was assessed for violating the limit state of cracking of the dam, which may cause only economic losses.
F.17 Transfer of existing technologies, know-how, methods and procedures into practice
COBISS.SI-ID: 5024353A web application (http://ice4risk.slo-projekt.info/analysis/) for the prediction of the approximate IDA curves of reinforced concrete structures was developed in order to demonstrate the applicability of the proposed web-based methodology for approximate IDA. The web application makes it possible to predict the seismic response parameters with higher accuracy than that which can be achieved by the currently available approaches in various standards and guidelines.
F.06 Development of a new product
COBISS.SI-ID: 5343329Newly emerging social and technological trends are changing business processes as we know. There is an emergent need for novel distributed software platforms capable of addressing the real-world needs of scientific and engineering AEC community. To present the benefits of the above-mentioned computing environment services, a web application for prediction of approximate IDA curves has been developed. In this paper, an overview of the ICE4RISK project as well as a brief description and discussion of the underlying technologies used in the development of the computing environment is provided.
