Case histories of damaged buildings, the patterns, and the failure mechanisms are discussed in this paper.
Experimental results concerning the hysteretic response, the shear strength at cracking and at ultimate, the energy dissipation capabilities, the cracking patterns and the failure mode of the tested beams are presented and discussed.
Decreases in reporting patterns and the failure of the educational efforts to increase the likelihood of reporting, as shown in our results is critically relevant for disease surveillance since passive HPAI surveillance and therefore the control of infection in rural areas depends on people's willingness to report.
The design method is to estimate the failure pattern parameters and the failure signal parameters first, and then use the parameter estimates to construct the adaptive failure compensation controller, the control law calculation is done simultaneously with parameter estimation without explicit failure detection.
For the flange-single web (but not the flange-double web) joint, bonding transformed the wavy fracture pattern and quadrupled the failure load.
More importantly and for the first time in related literature, the use of DIC enables to relate AE to the strain fields during loading, the final damage pattern and the ultimate failure mechanism.
The official, L. Nick Lacey, the acting director of the Flight Standards Service, said the problem at Alaska Airlines was not simply the specific flaws found, but the pattern of errors and the failure to correct them.
Under cyclic loading, due to the low cyclic fatigue damage behavior and for the fact that failure always takes place in concrete which is a quasi-brittle engineering material, all the tested beams could exhibit a more quasi-brittle failure pattern, and consequently the flexural failure of the beams presents a stronger size effect compared with that under monotonic loading.
Influences of concrete parameters on the crack pattern and failure modes of the dam prototype during the event are discussed.
The analyses results show good agreement with the experimental data regarding load displacement response, crack pattern and debonding failure mode when the cohesive bond model is used.
