A Continuous Damage Index for Seismic Reliability Assessment of Structural Steel Elements
Based on experimental investigations using steel plate elements subjected to cyclic axial loading, a continuous damage and/or deteriorating process is examined. In order to describe intermediate...

A Study of Seismic Reliability of Base Isolated Building Comparing with Non Base Isolated Building
An approach to discuss the difference between reliability of base-isolated buildings and that of non base-isolated buildings is presented. The fragility analysis method in PRA procedure...

Aseismic Reliability of a Strengthened R.C. Single Story Industrial Building
Based on results of seismic hazard analysis for a considered site, seismic reliability of a strengthened RC single-story industrial building against collapse has been evaluated. Inelastic...

Durability Analysis of Reinforced Concrete Structures

Assessment of Component Safety Due to Common Cause Events
This paper demonstrates the use of Modified Fault Tree Analysis (MFTA) and Modus Tollens Deduction (MTD) techniques for assessing the safety of redundant components due to common cause...

Fuzzy Reliability Analysis for Structural Systems with Continuous States of Failure
When there exist continuous transition states from the completely safe states to the completely failed states for structural components, the whole structure would behaves in the same way....

Damage Evolution in Reinforced Concrete Members Under Cyclic Loading
The paper presents a new damage indicator D, valid for reinforced concrete sections under cyclic loading. D_Q, based on sectionally absorbed energies,...

A Topology Variational Method for Reliability Analysis of Structural Systems
A force method of structural analysis, named topology variational method, is used to compute the reliability of plastic framework. The system failure is defined in terms of a global response...

Failure Prediction for Non-Linear Structural Systems
A method is described that makes failure predictions for structures which are complex, nonlinear and expensive to evaluate on a computer. The method makes use of a non-linear response...

Reliability of Elasto-Plastic Structural Systems
This paper proposes a method for generating safety margins and failure mode equations for elasto-plastic structures where interaction of load effects is taken into account. Structural...

Adaptive Importance Sampling
An adaptive importance sampling scheme is presented which is based on the idea that as one samples, the knowledge of the failure domain increases. If one keeps modifying the importance...

Redundancy of Multistate Structural Systems
In the theory of structural reliability it is often assumed that the system and its members can have two performance or damage levels ie. they can either be functioning or failed. It is...

Examples of System Optimization and Reliability in Bridge Design
The objective of this paper is to present examples of system optimization and reliability in bridge inelastic design. The optimum solution is defined as the bridge of least weight, subject...

System Reliability of Semi-Submersible Platforms
This paper deals with the system reliability of semisubmersible platforms which are modelled as spatial frames and subjected to quasi-static extreme loads based on elasto-plastic strength...

A Structural System Reliability Analysis of Jacket Using an Improved Truss Model
An improved truss model for structural system reliability analysis of jacket structures is presented. The efficiency of the model makes it possible to carry out a large amount of ultimate...

Efficient Structural System Reliability Assessment by Monte-Carlo Methods
Monte Carlo methods can be used to good advantage since the required probability of failure is formulated as a multi-dimensional integral of the probability density function of the basic...

Assessment of Safety of Existing Buildings Using Fuzzy Set Theory
In this paper, an approach to estimate structural safety which may serve as a bridge between the theoretical and empirical approaches is explored. The new method combines subjective judgment...

Integrating Expert Opinion for Assessing Structural Performance
Many experts use linguistic values when expressing their judgment on structural performance. The concept of fuzzy sets is used in this paper to obtain consistent measures of values provided...

Reliability of Redundant Structures Under Time Varying Loads
Time-variant system reliability methods under Poisson pulse load processes are presented. Direct simulations based on incremental truss analyses are also performed. Small displacement...

Load Path Dependence of Structural Systems
