Structural Risk

The structural risk assessment and evaluation process is broken into the steps of Develop knowledge of as-built conditions, Determine local response characteristics, Create mathematical model, Perform global analysis, Determine acceptability, and Select retrofit procedure/Classify per evaluation procedure and each step discussed. These steps, in general, are major topics of their own and only a few of the primary engineering issues that affect the state of the art in this area are included in this paper. The development of conceptual retrofit schemes is also discussed. Many aspects of earthquake engineering are directly related to risk assessment and retrofit, including performance based engineering, characterization of seismic hazard, performance of nonstructural systems, costs of retrofit, and public policy. These subjects and their relationship to risk assessment and retrofit are briefly described.

Asbestos, thalidomide, and smog in the environment have all given spectacular evidence of the power of man-made chemical substances to harm people. Phenobarbitone, paracetamol, DDT and penicillin are chemicals that have given large benefits for small risk. Epidemiological evidence allows us to consider dose, response and cost for some of these. For new chemicals we try to assess risk before human exposure starts, using model test systems. The tests are based on studies of substances known to have caused harm to man. The methods of risk and benefit assessment are not perfect, so that post-exposure surveillance is necessary for new and old drugs, pesticides and industrial and environmental chemicals. Risk assessment then takes the form of a continuous review of chemical use, as the relative risks, costs, benefits and alternatives change with developing technology. Those at the exposure end may have interests that conflict with the interests of the rest of society, so that any evaluation process for the risks should include a process for winning the agreement of the people at risk. The case of 2, 4, 5-T shows how the scientifically difficult and socially fragile process of risk assessment and evaluation can easily be disrupted. We need more systematic processes of quantification and more robust processes for evaluation of risks from chemicals.

Regulations And Guidelines

UNSTRUCTURED DattaMeghe Institute of Medical Sciences has been declared as Deemed to be University [DMIMS (DU)] under section 3 of UGC Act, 1996 in the year 2005. The University examinations are conducted as per the rules, regulations and guidelines issued by the various Apical councils of India from time to time. The first University exam was conducted in the year 2006. DMIMS (DU) has initiated various reforms by its own in assessment and evaluation process based on needs. For any system to thrive, it needs to be constantly upgraded and critically evaluated. Therefore, a study is undertaken with this in mind and thereby aimed at evaluation and validation of the assessment and evaluation reforms formulated and implemented at DMIMS (DU) since its inception (year 2006).Need analysis for the assessment and evaluation reforms will be carried out on the basis of feedbacks and reports received from respective stakeholders (Students, Faculty and External examiners) from time to time. Outcome analysis of the Feedbacks and reports will be done subsequently after the implementation of the assessment and evaluation reforms. Further based on the outcome analysis, reforms will be validated into following parameters: Objectivity, Responsiveness, User friendliness, Residual component (not covered in above 3 parameters)and a satisfactory index will be derived. If satisfactory index for reform is 100%, it will be concluded that reforms are well received and good to excellent in nature. Total 33 assessment and evaluation reforms have beenimplemented since year 2006. These reforms will be categorised into Pre-Examination (n=18), On Site Examination (n=05) and Post Examination (n=10), and in each category, they will befurther classified into academic (Total =15) and administrative (Total = 18) on the basis of their domain for the ease of structuring and implementation.All the 33 reforms will be validated on the basis of defined parameters. They will be found satisfactory.

Risk assessment involves the study of vulnerability and hazards. When focused on flood events, such an analysis should evidently include the theoretical and practical study of floods and their behavior. Nevertheless, risk assessment is not useful if the results are not subsequently used for more effective management and planning by local authorities and qualified personnel. The risk evaluation process is composed of a set of actions, each of which requires different inputs. In fact, the results of one action are used as the input for another. This paper describes a semantic model for the study and management of floods with a view to elaborating a conceptual framework and designing a knowledge base. The model is based on the environmental assessment ontology and demonstrates how a brief ontology can be generated.

In-line inspection (ILI) of the Trans Alaska Pipeline System (TAPS) using high resolution metal loss tools indicated 77 locations with suspected minor mechanical damage features (MDF). The tools used are able to detect the presence of a suspected feature, and measure indented dimensions, but are insufficient to detect the presence of cracks or gouges needed to reliably assess feature severity based solely on the ILI data. Excavations of 42 sites deemed most severe provided important field data characterizing residual deformation dimensions, the occurrence of gouges or cracks, and allowing a reliable field assessment of defect severity. Upon completion of the excavations, 35 possible MDF locations remained unexcavated. An engineering evaluation was undertaken to assess whether or not these remaining minor MDF pose a threat that is significant enough to warrant excavation. Multiple assessment methods were utilized including deterministic, probabilistic, and risk assessment methods. The probabilistic assessment of 35 unexcavated MDFs was performed using PCFStat; or Pressure Cycle Fatigue Statistical Assessment, which uses Monte Carlo simulation to estimate remaining fatigue life. PCFStat performs 1,000’s of simulations for each case where the input parameters are randomly selected from expected distributions. Of particular importance is the fatigue environment of the location. The results of the probabilistic assessment were used to estimate the potential for failure of remaining MDFs. The results suggest that 25 of 35 unexpected damage features had a POF of less than 10−4 over the remaining expected pipeline life cycle and thus are unlikely to fail. Alyeska considered a combination of probabilistic, deterministic and risk assessment results to decide on the actual locations to be examined. The results of probabilistic analysis also were found to support the outcome of the operator’s risk-based evaluation process.
