Structural Safety is one of the most important factors of any aerospace product. Until recently, a design is considered to be robust if all the variables that affect its life has been accounted for and brought under control Safety factor cannot, by themselves, guarantee satisfactory performance and they do not provide sufficient information to achieve optimal use of available resources. The meaning...
A new approach of structural safety assessment for an existing rigid-frame arch bridge, constructed from multivariate and multi-layer analytic model. The assessment model of structural safety of existing rigid-frame arch bridges on the basis of technical condition, static loading test, dynamic loading test and load-carrying capacity, and the index system is proposed according to multivariate. In this...
Although there are many methods to calculate the settlement of ground, it is difficult to obtain accurate results due to the complexity of geotechnical characteristics, and then the safety of ground and structure cannot be ensured. Based on the safety, influence of soil characteristics on ground safety is discussed by means of reliability theory, and methods to assure the structural reliability are...
Based on the butterfly arch continuous girder bridge in HeiHe, China, this paper mainly deals with a quantitative risk analysis for V-shaped pier during the construction process, by using Analytic Hierarchy Process - Grey Correlation Analysis method. Firstly, hierarchical model of risk analysis is established, and structural property is identified as the highest risk factors during V-shaped pier construction...
Service life prediction is an important aspect of structural safety evaluation. Based on periodical or non-periodical testing results of existing structures, some comprehensive evaluation indices of time series can be obtained by reliability assessment or other evaluation methods. For the problem of remaining service life prediction, existing structures can be regarded as grey systems. Combined with...
High Reliability and operational safety are most important requirements of an aerospace product. Many aerospace standard guidelines are followed during design phases and after many iterations the product parameters are established. The conventional design practices do not take variability in to account. Probabilistic structural analysis, unlike traditional methods, provides a means to quantify the...
Protecting the security of the dam is a vital problem for the reasonable use of the water resources, so it is important and meaningful to research methods of assessing the safety of dam for which is related with the national economy and the people's livelihood, and it is necessary to build a system to estimate the security risk of dams. The dam failure disaster risk is regarded as main researching...
Considered in assessing durability of concrete structures on the basis of factors was finished. Concrete structures for specific components, to assess the durability nodes do not contain many intellectual, select the most impact on the durability of concrete structures to assess factors as indicators, used uncertainty comprehensive evaluation model, the establishment of concrete structures to assess...
To find an effective model for safety assessment of civil engineering structures under the uncertainty and data lack, the unascertained set was introduced to measure the reliability and a safety assessment model with credible identification principle was set up. Then, engineering practice for the reliability assessment of a cable-stayed bridge showed that the model proposed here can complete the safety...
Building information modelling (BIM) is only a tool in the procurement of a building, but it is changing the way the whole process is undertaken. Having a single model which is used by all disciplines requires a different management structure and by consequence a restructuring of the resources required to complete a project.These changes are encompassed in Integrated Practice and more recently Integrated...
