A large number of probabilistic earthquake occurrence models are currently available for seismic hazard assessment. This paper reviews the basic assumptions of the various models, summarizes their stochastic representations and discusses the parameters needed for applications. While the Poisson model is one of the most commonly used in practice it is limited in its representation of the physica...

Although probabilistic seismic hazard analysis (PSHA) is the most widely used method to assess seismic hazard and risk for various aspects of public and financial policy, it contains a mathematical error in the formulations. This mathematical error results in difficulties in understanding and application of PSHA. A new approach is presented in this paper. Seismic hazards derived from the new ap...

Seismic hazard analyses, either in a deterministic (DSHA) or probabilistic (PSHA) framework, are both commonly adopted for evaluating earthquake risk. Although different in methodology, both approaches involving tedious calculation are certainly a computer-aided analysis. For Taiwan, a few PSHA studies have been conducted, but not a single comprehensive DSHA study is yet available for this regi...

Cylindrical liquid storage tanks are considered as vital structures in industrial complex whose nonlinear dynamic behavior is of crucial importance. Some of these structures around the world have demonstrated poor seismic behavior over the last decades. There are several methods and techniques for rehabilitation and reducing damages in these structures which among them passive control devices, ...

The assessment of seismic performance of existing structures is becoming an important problem in earthquake engineering. Some important ructures are considerably old and, therefore, their strengths and ductilities are less than strength and ductility demands because of changes in codes and design methodologies. Such structures must be strengthened to resist future earthquakes. First, a structur...

Bengkulu City is an area in Indonesia that has a high seismic intensity. This very vulnerable to undergo earthquakes. Therefore, there necessity study the hazard assessment this area. paper presents vulnerability based on ground response analysis combined with probabilistic assessment. The soil profiles around are investigated using geophysical survey by microtremor and analysis. motion of soft...

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...
