This study presents a methodology for developing fragilities of concrete gravity dams to assess their performance against hydrologic and seismic hazards. Fragility analysis, which depicts the uncertainty in the safety margin above specified hazard levels, is a fundamental tool in a PSA.

Estimation models are developed for different combinations of factors and model performance, which is measured through the standard error, is observed to improve with additional factors. A probabilistic safety analysis PSA provides a rational safety assessment and decision-making tool managing the various sources of uncertainty that may impact dam performance.

Design by advanced analysis uses non-linear structural analyses to predict system performance measures. The predicted oscillatory motion responses, based upon prior theoretical work on the linear motion of grounded ships, are compared to results from the small-amplitude wave experiments.

Also, vortex-induced vibrations of the bridge were investigated, and such events were carefully identified. The buckling coefficients for stress gradient situations were given.

The proposed damage growth model is extended into the stochastic domain by considering fluctuations in the free energy, and closed-form solutions of the resulting stochastic differential equation are obtained in each of the three cases mentioned above.

An estimate of the distance a grounded ship may migrate in a given time would help ship owners, insurers, and government officials make critical decisions in the initial hours after a ship grounding. This method was applied to evaluate the response of several long-span bridges and the results compared with those obtained from a single-mode analysis procedure.

Developing effective mechanisms for removing pollutants from soil: Moreover, the chaos expansion gives more detailed probabilistic description of the eigenvalues and the eigenvectors.

Because of the complexity of modern structures, full-scale measurement is the only assured way to determine model parameters. Furthermore, the statistics of the errors in the regression fit can be derived in terms of a local second-order fit of the true mean function. Reliability and Bayesian Approaches to the Probabilistic Performance Based Design of Structures Performance based design PBD is emerging as the guiding principle for the next generation of structural design specifications.

One-dimensional compression of kaolinite assembly is simulated using a randomly generated particle numerical assembly. To circumvent these problems an efficient method for estimating the coefficients is proposed.

This regression method is well suited for subsequent minimization by the trust-region algorithm because the support of the local regression kernel can be adapted to the size of the trust-region. Stress-strain behavior and strength, failure patterns and shear banding, volumetric response and dilative properties were analyzed in view of the inherent material anisotropy.

You cannot take chivalrous measures while dealing with a project of this importance. Combined with results from a section-model test, the coupled analysis can yield valuable information on the suitability of a deck cross section and the structural configuration. A cross-anisotropic constitutive model was derived based on the existing model for isotropic materials.

Triaxial tests on fiber-reinforced sand specimens were performed to verify the approach used in the failure analysis.

The testing setup was carefully designed in the first series of tests phase 1 to allow the form of local buckling failure while restrict distortional and lateral-tortional buckling. Using a systems-based approach, a rational means was developed for evaluating the utility of structural condition assessment techniques.

Therefore, two series of bending tests on industry standard cold-formed steel C and Z-sections were performed and presented in this dissertation.

The commonly used lower-order perturbation-based SFE analysis is often limited to linear or mildly nonlinear problems with small variability.

Here, the micromechanics of the fiber composites is investigated. Recommendations for rational design of these mitigation devices are also provided.

To obtain a surrogate surface, which is simply an estimate of the mean of the objective function, local linear regression is used.

In recent years, the finite element method FEM has gained considerable acceptance in the solution of problems governed by the viscous, incompressible flow equations.

The evolution of the inclination of the plastic strain increment vector to the hydrostatic axis with pressure was evaluated and analyzed using different elastic models. The macroscopic failure stresses predicted using the criterion developed compare favorably with actual results from tests on fiber-reinforced soils.

The measured responses were compared with predictions obtained from a multi-mode frequency-domain approach, which was able to capture the coupling between closely spaced modes of the structure.

These transient responses are obtained via numerical simulation.Jul 31,  · Civil mint-body.com Structural Engineering Seminar Topic - Latest Civil Engineering Seminar topics. This site belongs to a structural engineering professional and researcher.
